Customer Testimonials
Edwin & Harold were professional & very congenial. My problem was addressed the same day as my scheduled appointment.
Knowledgeable, good service , great customer service from booking with Amanda all the way to having the technicians in my home
Excellent customer service! Took the care and time to patiently explain everything and listen to my needs and concerns and offered multiple options to consider at my own pace.
Edwin and Harold did a great job and explained everything that they needed to fix. Peace of mind is so important with electrical work.
Prompt service, no B.S. Honest people doing honest work, and always very polite and personable. Completely satisfied with their service.
Had Erwin and Harold out for a second time to do more work in our home we are renovating. I have no complaints about this company, they are honest and give plenty of options to work with your budget. Respectful, understanding and very thorough explanation of their work. Highly recommend you get a quote from them before paying double to the larger companies!
Edwin was very informative and respectful. Quick and effective work. Very thorough and good at his job. He discovered that every outlet that was worked on previously by a unlicensed handyman were done incorrectly. My home could have burned down, thankfully i caled a professional. I would recommend him everytime
Erwin did a great job on the lights in are den he was here when he said he would and gave a far price for what he did.
Erwin did an awesome job! Super professional, on time, and really knows what he’s doing. Everything came out great, and he made sure it was done right. On top of that, he’s just a really nice, friendly guy—easy to talk to and made the whole process stress-free. Definitely someone you feel comfortable having in your home. I’d 100% recommend him to anyone looking for a reliable electrician!
Erwin and Harold were absolutely fantastic. Courteous and clean service. Very professional. Advised me on what was needed to bring my kitchen oven up to code and accomplished my installation quickly and same day. Estimate was equal to what I paid. Very honest workers and professional experience. 10/10! Will be calling them for everything in the future for electric. Amanda, the lady who I scheduled the appointment with was also friendly and professional and answered all my questions. Overall a fantastic company, I couldn't speak highly enough of them!
The team was wonderful. They went above and beyond to make sure that I was satisfied, even offering to help me with a few loose ends on other projects. Their reprices were fair and upfront with no hidden fees, and I never doubted the integrity of their work. I will be coming back to them for anything electrical in the future
Harold came in, was very proffesional. Fixed our outlet and panels in a timely manner and were very accomodating. Would reccomend.
The outlet wasn't working he came and fixed it quickly and was very respectful.
This is my first experience with Edinson Electrical Solutions. I was very pleased with their service and will use them for all my electrical needs in the future. They were very professional and respected my house. Thank you very much.
I have used Edwin a few times for my house and each time he is very customer oriented, shows up when he says, and does a fine meticulous job. I recommend him highly if you are looking for an electrician.,
Jr and Harold helped me with an electrical issue where I kept losing power in my bedroom and living room. They came out, diagnosed the problem quickly, and fixed it the right way. What really gave me peace of mind was their lifetime craftsmanship warranty. It’s great knowing the job was done properly and that they stand behind their work. Highly recommend them!
Erwin was amazing. We needed an entire new panel, it was waterlogged and he worked the same day doing everything over for us. He was so amazing that he even got us a pizza out of the kindness of his heart. I definitely want them any time I have any other issues. 10/10 would recommend.
Erwin is great at what he does he came through for me and my family during a snowstorm storm so if you have any electrical problems I recommend you give him a call
Great service. Quick efficient and very good customer service. Will definitely book with Edinson Electrical solutions again.
They truly came through for us. This wasn’t an easy project—our entire parking lot was without lighting—but their team handled it quickly, safely, and professionally. They diagnosed the issue, coordinated the work, and had everything fully operational in just two visits. We’re grateful for their efficiency and expertise.
The electricians(Erwin Harold and their crew) did a wonderful job. Erwin explained step by step in details on the things they were going to work on before they did the job. They accommodated everyone in the household especially our autistic son. With all the cosmetic work that had to be done, in the end,it looked like no damage to the house was even done. Thanks to them now we have permanent power instead of partial power. We will definitely recommend them to everyone.
Erwin and Harold from Edinson Electrical Solutions visited us to work on the dishwasher, the circuit breaker panel, outlets and possible installation of a new outlet box in the basement. Erwin was very thorough. He went through all the requirements of what needed to be done and provided options for us to pick. We wound up putting in a new outlet box for the dishwasher (which he diagnosed as needing replacement). He installed a new whole house surge protector at the circuit breaker panel. He fixed a few of the troublesome outlets. We decided not to install the outlet box in the basement at this time. What was impressive was the time he spent explaining the pros and cons of what needed to be done. I appreciated the explanations. They did an outstanding job for us and not was reasonable for the work that was performed.
Erwin and team were great! Provided multiple options for our project so we could decide what works best. It was a large project, upgrading 2 panels, removed 1 meter and went to 200 amps. Communication was great throughout and he made us a priority. We used Edinson for a previous project as well, we will continue to use them and would highly recommend them for a small or large project.
Harol y Jr. son electricistas increíblemente profesionales y amables. Se tomaron su tiempo para asegurarse de que todo estuviera bien y fueron honestos con nosotros sobre los precios. Nos ayudaron con todas nuestras dudas y nos brindaron un servicio excelente. Harol and Jr. are incredibly professional and friendly electricians. They took the time to make sure everything was okay and were honest with us about the prices. They helped us with all our questions and provided excellent service.
Erwin came out and was very professional. He explained everything and did not rush. I would absolutely recommend him to others.
Juan was excellent! He showed up on time, was very professional, and completed the job quickly and neatly. Great communication and reliable service. I’ll definitely call him again when I need electrical work done.
Erwin and Harold did an excellent job replacing many outlets and lights for our remodel. They also upgraded several switches for us. They were very respectful of our house, cleaning up after themselves as they worked. We will be calling them in the future for other work we will need to have done.
Erwin came during a same day emergency that required a readjustment and reinstallation of improperly connected wires connected from the ceiling to make sure the lights worked properly. He was professional and made sure everything stayed working properly. Totally would recommend! Five Stars!
Erwin came to fix an electrical issue I had with my lights not working in my bathroom. He was very flexible with when I was available and efficient in getting the issue resolved quickly and professionally. I would recommend this company 100%!
Erwin was amazing! We called when our circuits when being tripped and we didn't know why. He came and was professional and courteous. He explained everything he was doing and checked in multiple times so we knew what to expect. The job was bigger than he expected but he stayed calm and worked diligently until it was finished. He gave us multiple professional recommendations before he left for things we can improve our efficiency.
We were having some intermittent issues with power in our house. Erwin came out and checked everything out for us. He was great and answered all of our questions about the state of our wiring and helped us plan out future projects. The price was well worth an hour of his expertise, and they’ll be at the top of our list when we do start on renovations.
Amazing service! Erwin was extremely professional and resolved my issue quick! I would highly recommend.
they was fast and cleaned up. Showed and explained everything that happened. it was very pricey but they did a good job.
Erwin was great, I had a partial power in my room and my husband found him on Google he came right away to check and fix the problem.
Edinson Electrical was referred to us by our realtor, Rudy Amelio. They were available very quickly to do the work. Erwin checked the site; and Harold got started immediately. We had a long list of small projects which they completed rapidly a d skillfully. Harold was very respectful of our property. They found some additional items to repair and checked and double checked everything. They were both very polite, responsible, thorough, as well as informative. Erwin and Harold aee some of the nicest, most honest people I’ve had the pleasure of meeting and working with. Highly recommend!
I recently purchased a house, erwin and his crew, help us with a City requirements list, pull the permits i guide us on the entire process
I had problems after all the rain we had with my GFI outlets outside. Edwin came in a timely manner and completed it neatly and correctly. They are both working perfectly and safely now. I highly recommend this company!
I live in an apartment complex where several units lost power after a tree came down during a storm on Father’s Day. It was pouring, and honestly, we thought we’d be without power for a long time. But Edinson Electrical Solutions showed up quickly and got right to work. They were professional, focused, and clearly knew what they were doing. It was impressive to see how they handled such a big job under tough conditions. Power was restored to all the apartments faster than we expected. Truly grateful for their dedication and the quality of their work.
We had an emergency when a tree fell and knocked out our power even on Father’s Day and during heavy rain. Harold and his crew from Edinson Electrical Solutions showed up fast, handled everything safely and professionally, and got our power back on with excellent work. In a stressful moment, they brought peace of mind. We highly recommend Edinson Electrical Solutions for their quality, responsiveness, and dedication!
I contacted Erwin for help with 2 sub panel installations at my residence and from the moment I called him to the moment he walked off my property it was an example of customer-first professionalism. If you want to have a quality job done, with a friendly, safe and professional electrical contractor, look no further. He handles everything from A to Z and does not consider the job done until the customer is satisfied. I cannot say enough positive things about my experience with him and his team. Outstanding service. If you choose this company, you won’t have any problems
I had a great experience with Edinson Electrical Solutions. They helped make my house much safer by upgrading all the smoke alarms, fixing some wiring issues with my baseboard heaters, and installing a electronic surge protector. Their work was very thorough and professional from start to finish. I’m extremely satisfied with the job they did and would definitely recommend them to anyone looking for honest, high quality electrical work.
Juan and his crew were very professional, clean and respectful of our home. They fixed a ceiling fan and installed all new smoke alarm / carbon monoxide detectors, efficiently throughout the house.
We recently purchased our forever home and spent hours searching for a highly reputable electrician to help us with a large project. Erwin is the epitome of professional; he came for the estimate and talked us through every viable option to make major upgrades to our VERY outdated knob and tube electrical system. He was very receptive to our input and made us feel like we put a plan together as a team. His dedication to his clients is very apparent as he followed through with all the work he said he would do within the timeframe he provided; not only that, but he went above and beyond to ensure that we were left feeling safe and secure before he wrapped things up. He completely alleviated all our initial concerns by the time the project was done and has remained in contact to make sure everything has continued running smoothly. It’s rare to find someone that genuinely cares about others in the capacity that he does with the skills to boot. Don’t just take my word for it; give him a call and I guarantee that you will have him on standby for all your current and/or future needs. Keep up the great work!!!
Honest, reliable and quick to respond. It doesn’t get better than Edison Electrical Solutions.

I’m very impressed with Edinson Co, specifically having worked with Erwin to estimate and assess an older century house’s electrical system. The process was smooth, thorough and actually enjoyable. Erwin is a down to earth guy and will have no problem keeping you aware of what needs to be done work wise, albeit very kind, funny and friendly to talk with. Never once did I feel pressured or unsure about any of his work. The process was simple enough to any homeowner; going off a general inspection and digging even deeper into whatever pops up on the report is exactly what Erwin did. His report was thoroughly informative after taking time checking for GFI circuitry and for k&t. If you have an older house and are interested in finding out what kind of projects you might encounter, Erwin definitely will shed some light on the situation. I am so grateful Erwin was referred to me, being that finding an honest and dedicated electrician is golden nowadays. Thank you so much Erwin!
Erwin arrived on time. The problem was fixed. Very professional. I would call them again

COMPLETED SERVICE CALLS
Electrical Subpanel Repair Service
Electrical subpanel repair begins with thorough diagnostic work to identify what is actually wrong rather than guessing at causes. Our team starts by reviewing the symptoms the customer has experienced including any tripping breakers, hot equipment, flickering lights, or other electrical problems on circuits served by the subpanel. We then inspect the subpanel exterior and interior for visible signs of trouble including discoloration, heat damage, corrosion, or recent modifications. Infrared thermometer readings on every breaker reveal heat patterns that often pinpoint problem areas. We measure voltage at the feeder connection and at branch circuit terminals to confirm proper supply to and through the subpanel. Each step contributes information that narrows down the possible causes. Edinson Electrical takes the time to perform proper diagnosis because rushing to parts replacement often misses the actual problem. Allentown customers benefit from accurate diagnosis that leads to lasting repairs.
Improperly bonded neutrals are one of the most common subpanel issues we encounter, particularly on installations performed by previous owners or non-licensed contractors. The neutral bar in a subpanel must be isolated from the panel enclosure and the equipment grounding bar. The bonding screw or jumper that connects neutral to ground in the main panel must not be installed in subpanels. When this requirement is violated, parallel paths for neutral current develop that can energize the equipment grounding system and metal enclosures throughout the building. Correcting this issue involves removing the bonding connection in the subpanel, installing a separate isolated neutral bar if one is not already present, and ensuring that neutrals are completely separated from grounds within the subpanel. This single repair often eliminates a wide range of symptoms across multiple circuits.
Feeder connection problems at both the main panel and the subpanel cause symptoms that can be confusing without proper diagnosis. Loose connections at the feeder breaker in the main panel generate heat that affects the feeder breaker and the conductors. Loose lugs at the subpanel main lugs cause similar heat problems and may affect every circuit served by the subpanel. We retorque accessible connections during repair visits using calibrated torque tools because manufacturer specifications are precise. Connections that are too loose cause arcing and heat, while connections that are too tight can damage conductors and threads. Proper torque restores reliable electrical contact and resolves heat-related symptoms throughout the subpanel.
Feeder conductor problems sometimes appear in subpanel repair visits when the original feeder was undersized or improperly installed. Three-wire feeders are a particular problem because subpanels require four-wire feeders for code-compliant operation. Two-wire feeders without separate neutral and equipment grounding conductors are simply incorrect for subpanel installation. When we encounter these conditions, the repair involves running new feeder conductors with the appropriate four conductors. Damaged feeder conductors from age, pest activity, or physical damage similarly require replacement of the affected sections back to the nearest accessible junction box. We coordinate any drywall access required for these repairs with customers in advance.
Branch circuit breaker problems within subpanels follow the same patterns as breaker problems in main panels. Tripping breakers, hot breakers, breakers that will not reset, and breakers showing visible damage all warrant evaluation and replacement when appropriate. We use the correct manufacturer-listed breakers for each panel rather than mismatched or classified breakers that void panel listings. AFCI and GFCI breaker failures in subpanels require the same testing and replacement procedures we use for main panel breakers. Identifying the root cause is essential because replacing a tripping breaker without finding the underlying circuit problem rarely produces lasting results.
Grounding deficiencies in subpanel installations sometimes require correction during repair visits. Subpanels in the same building as the main panel rely on the equipment grounding conductor in the feeder to maintain proper ground reference. When this conductor is undersized, missing, or improperly terminated, ground faults may not develop enough current to trip breakers quickly. Equipment served by the subpanel can remain energized during fault conditions, creating shock hazards. Detached building subpanels have their own grounding requirements that vary by code edition and local interpretation. We address grounding completely during repair work because partial corrections leave the system vulnerable.
Documentation completes every subpanel repair we perform. We update the panel directory to accurately reflect current circuit assignments because subpanel directories often become inaccurate over time as circuits are added, removed, or rearranged. Photos document the work performed for customer records and for any future service work. Written notes explain what was found, what was repaired, and any recommendations for additional work. Edinson Electrical leaves every subpanel installation in better condition than we found it. Allentown customers receive subpanels that operate safely, support the areas they serve, and provide clear records of past work. Quality repair work supported by proper documentation builds long-term electrical reliability.

The Importance of a Licensed Electrician for Electrical Subpanel Repair in Allentown
Hiring a licensed electrician for electrical subpanel repair in Allentown is essential because subpanel work involves specific code requirements that DIY work routinely gets wrong. The proper separation of neutral and ground in subpanels is one of the most commonly violated requirements in residential electrical work. Mistakes create real hazards including shock risks from improperly bonded neutrals and fire risks from undersized or improperly terminated conductors. Licensed electricians understand the differences between main panels and subpanels, the four-wire feeder requirements, and the specific grounding considerations for various installations. Pennsylvania requires licensing for this kind of work because of the safety implications. Insurance companies investigate subpanel installations after fires and electrical incidents, and unlicensed work can result in denied claims. Licensed contractors carry liability insurance and workers’ compensation that protects customers throughout the repair process. They also stay current on continuing education that covers code updates, panel manufacturer specifications, and new diagnostic methods. Edinson Electrical is fully licensed and insured in the State of Pennsylvania with extensive subpanel repair experience. Our lifetime craftsmanship warranty backs every repair we complete, and we provide the documentation customers need for their property records.
FINANCING AVAILABLE
We offer financing through Synchrony to make larger electrical projects more manageable for homeowners.
LIFETIME WARRANTY
Our work is backed by a lifetime craftsmanship warranty, giving you long-term confidence that the job was done right and built to last.
LICENSED & INSURED
Edinson Electrical is fully licensed and insured, giving you confidence that your electrical work is handled by qualified professionals.
Commonly Asked Electrical Subpanel Repair Questions
Subpanel problems can be confusing because the symptoms often appear on branch circuits served by the subpanel rather than at the subpanel itself. The questions below cover what customers across Allentown and the Lehigh Valley most often ask before scheduling subpanel repair.
Several signs indicate that a subpanel may need professional attention rather than continuing to operate without inspection. Frequent breaker tripping on circuits served by the subpanel often points to subpanel-level problems including loose feeder connections, improper grounding, or weakened breakers. Subpanels that feel warm to the touch under normal load are showing signs of internal problems that warrant evaluation. Buzzing or crackling sounds from the subpanel indicate active electrical problems that should not be ignored. Visible signs including scorch marks, melted plastic, or evidence of water intrusion all require prompt professional attention.
Symptoms on branch circuits sometimes point to subpanel problems rather than individual circuit issues. Lights that flicker simultaneously across multiple circuits served by the subpanel suggest loose feeder connections. Voltage problems affecting all subpanel circuits but not main panel circuits point to subpanel-level issues. Equipment damage on circuits served by the subpanel may indicate improperly bonded neutrals creating voltage instability. We diagnose these symptoms by tracing the affected circuits back to their common source.
Specific installation conditions warrant evaluation even without active symptoms. Subpanels installed by previous owners or non-licensed contractors often have hidden problems that have not yet caused visible symptoms. Subpanels in finished basements that have experienced water intrusion need evaluation for corrosion damage. Older subpanels with discontinued breakers or signs of past modifications benefit from inspection. Edinson Electrical performs comprehensive evaluations that identify both active problems and developing conditions. Allentown customers benefit from electricians who can spot issues before they cause visible failures. Catching problems early often prevents the larger consequences that develop when they progress.
A buzzing or humming subpanel is showing signs of active electrical problems that warrant prompt professional attention. The most common cause is loose connections somewhere in the panel that are generating arcing or vibration. Loose lugs at the feeder connection, loose breaker terminations, or loose neutral or ground bar connections all create vibration that produces audible noise. The noise itself is not necessarily dangerous, but the conditions causing it are progressing toward more serious problems including overheating and potential fire.
Specific noise patterns sometimes point to specific causes that an experienced electrician can recognize. Steady hum at line frequency suggests inductive loads on circuits or transformer-like effects in damaged components. Intermittent buzzing or crackling typically indicates arcing at a loose or damaged connection. Mechanical sounds like clicking may come from breakers operating or relays cycling on connected equipment. We listen carefully during diagnostic visits and use this information to narrow down possible causes.
Failing breakers and devices sometimes produce noise as their internal contacts deteriorate. Worn breaker contacts can vibrate slightly under load, producing audible buzzing that grows louder over time. Damaged AFCI or GFCI breakers with electronic component failures sometimes produce noise as well. The right response depends on the specific cause, and our diagnostic approach identifies the actual source rather than just assuming. Edinson Electrical addresses subpanel noise problems with appropriate repairs rather than ignoring symptoms or making generic recommendations. Allentown customers benefit from accurate diagnosis that solves the actual problem. Subpanel noise should never be ignored because the underlying conditions typically worsen over time.
Most subpanel problems can be repaired in place when the underlying panel is in good condition. Loose connections, individual breaker failures, neutral bonding errors, and minor grounding issues are all repairable within the existing subpanel. We address these problems during service visits and restore proper function without the time and cost of replacement. Subpanels from quality manufacturers operating in protected indoor environments often serve for decades with periodic repair work.
Certain conditions, however, indicate that subpanel replacement is more appropriate than continued repair. Significant heat damage to the bus bars, panel enclosure, or main lugs typically cannot be repaired in place. Subpanels that have experienced water damage, fire damage, or significant physical damage often need replacement for safety reasons. Subpanels from manufacturers with known safety issues, including Federal Pacific and Zinsco, warrant replacement regardless of current symptoms. Undersized subpanels that cannot support actual demand sometimes warrant replacement with larger panels rather than continued operation at capacity.
The economics of repair versus replacement depend on the specific situation. Multiple repairs over a short period on an aging subpanel can approach the cost of replacement, at which point replacement makes more economic sense. Replacement also provides opportunities to address related improvements including modern AFCI and GFCI protection, larger capacity for future expansion, and updated grounding methods. Edinson Electrical provides honest assessments based on actual panel condition rather than steering customers toward the more expensive option. Allentown homeowners appreciate the straightforward guidance that helps them make informed decisions. Sometimes a small repair extends panel life significantly; other times replacement is clearly the better path forward.
Subpanel repair costs vary based on what the actual problem turns out to be and the scope of work needed. Simple repairs like correcting an improperly bonded neutral, replacing an individual breaker, or retorquing connections fall within a modest price range. More complex repairs involving feeder conductor replacement, extensive grounding corrections, or significant component replacement cost more because of the additional time and materials involved. We provide written estimates for any repair work beyond basic diagnosis so customers understand the cost before authorizing the work.
Several factors affect repair pricing that customers should understand. Subpanel accessibility matters because work in finished spaces requires more setup and patching than work in unfinished areas. Older subpanels or discontinued panel brands sometimes require special-ordered parts that cost more and take longer to obtain. Underground feeder problems are typically the most expensive to address because excavation may be required. Detached building subpanels can require trips between the main building and the detached structure that affect labor time.
Bundled repairs during a single visit often produce better value than separate service calls. Customers who address multiple known issues during one appointment benefit from concentrated work. Common bundles include correcting bonding issues while also retorquing feeder connections and updating panel labeling. We provide options at different price points where appropriate and explain the tradeoffs clearly. Edinson Electrical prices repair work fairly without hidden fees or surprise charges. Financing through Synchrony helps with larger repair scopes. Allentown customers value the transparent pricing that supports informed decisions about their subpanel work.
A subpanel breaker that trips repeatedly is responding to real conditions on the circuit it protects, just like main panel breakers. The most common cause is simple circuit overload where total demand on the circuit exceeds the breaker rating for an extended period. Garage subpanels often see overloads when high-amperage tools or EV chargers run simultaneously with other loads. Basement subpanels may see overloads when space heaters, dehumidifiers, and entertainment equipment all run together. The solution may be redistributing loads, adding circuits, or reducing simultaneous demand on specific circuits.
Short circuits and ground faults cause more serious tripping that requires professional diagnosis. A short circuit occurs when hot conductors contact each other or the neutral, creating an instant high-current path that trips the breaker immediately. A ground fault happens when a hot conductor contacts a grounded surface or a person. Damaged extension cords, broken appliance cords, water intrusion in outlets, and pest damage to wiring all create these conditions on subpanel circuits. We isolate the source through systematic testing rather than guessing.
Subpanel-specific issues sometimes cause tripping that would not occur in identical circuits served by main panels. Improperly bonded neutrals create return current paths that can cause nuisance tripping of GFCI and AFCI breakers. Loose neutral connections at the subpanel cause voltage instability that affects breakers throughout the subpanel. Feeder voltage drop on long feeder runs sometimes causes nuisance tripping at the far end of branch circuits served by the subpanel. Edinson Electrical considers these subpanel-specific causes during diagnostic work. Allentown customers benefit from electricians who understand how subpanel issues differ from main panel issues. Solving the actual problem prevents repeated service calls for the same symptoms.
Subpanel repair restores existing components to safe, working condition without replacing the panel itself. Repairs address specific problems like loose connections, bonding errors, individual breaker failures, or grounding deficiencies. The existing panel enclosure, bus bars, and main lugs remain in service. Repair is generally less expensive than replacement and less disruptive because the feeder, branch circuits, and panel mounting all stay in place. Many subpanels operate for decades with periodic repair work because the major components are designed for long service life.
Subpanel replacement involves removing the existing panel and installing a new one in its place. The new panel may be the same size as the original or different, depending on whether capacity changes are part of the project. Branch circuits transfer from the old panel to the new panel during installation. The feeder may or may not need replacement depending on its condition and whether the new panel has the same amperage rating. Replacement projects take longer and cost more than repair but address problems that cannot be fixed within the existing panel.
The choice between repair and replacement depends on the specific situation. Quality subpanels with intact bus bars and good overall condition typically warrant repair when problems develop. Panels with significant damage, panels from manufacturers with known safety issues, and panels at the end of useful service life warrant replacement. We help customers understand the considerations during diagnostic visits and recommend the approach that makes the most sense. Edinson Electrical provides honest guidance rather than pushing the more expensive option. Allentown customers benefit from clear explanations of options and pricing for each approach. The right decision produces the right results for the long term.
Subpanel problems can range from minor inconveniences to serious safety hazards depending on the specific issue and conditions. Active overheating, burning smells, visible damage, or arcing sounds all indicate immediate safety concerns that warrant prompt response. Cutting power to the subpanel and calling for emergency service is appropriate when these conditions are present. Some subpanel problems are less severe but still warrant timely repair to prevent progression to more serious conditions.
Improperly bonded neutrals create specific hazards that may not produce obvious symptoms until something goes wrong. When neutral and ground are bonded together in a subpanel where they should be isolated, return current from circuits can flow through the equipment grounding system and metal enclosures. This condition can energize metal parts to dangerous voltages, particularly during fault conditions. People who touch energized metal during these events can receive serious shocks. The condition may not produce visible problems for years until specific fault conditions occur.
Failed neutrals create some of the most dangerous subpanel conditions. When the feeder neutral connection fails or weakens, voltage on individual circuits can rise far above normal as loads on one leg of the service overload the remaining neutral path. Equipment connected to affected circuits can be damaged immediately, and connected people can experience shock from energized neutrals. Failed neutrals are emergencies that justify immediate response. Edinson Electrical responds to these situations promptly because the consequences of delay can be severe. Allentown customers can call when subpanel problems develop, and we make every effort to respond quickly. The cost of prompt response is modest compared to the cost of injuries or equipment damage.
Most subpanel repair visits take between one and four hours depending on the complexity of the diagnosis and the scope of the repair. Simple problems that can be identified quickly and corrected with minor work fall on the shorter end of that range. More complex problems involving extensive diagnosis, multiple component replacement, or related work take longer. We never rush diagnostic work because the value is in accurate problem identification that leads to lasting repair.
Service interruption during subpanel repair is typically limited to the subpanel itself rather than affecting the entire property. The feeder breaker at the main panel can be turned off to deenergize the subpanel for repair work, leaving the rest of the home’s electrical service in operation. Some repair work can be performed with the subpanel energized using appropriate procedures and personal protective equipment, though we generally prefer to work deenergized when feasible. The brief outage on subpanel circuits is much less disruptive than full house outages associated with main panel work.
Intermittent problems sometimes extend the time required for accurate diagnosis. Symptoms that come and go cannot be diagnosed if they are not present during the service visit. We sometimes install temporary monitoring equipment or schedule return visits to catch intermittent problems in the act. Edinson Electrical communicates timing expectations clearly so customers can plan around the work. Allentown customers value the predictable scheduling and efficient repair work that follows accurate diagnosis. Most subpanel repairs are completed in a single visit when the problems are present and well-defined.
