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.

Jimmy Hoffman

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.

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.

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

Thomas Charles

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!!!

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!

Generator Installation Service

Generator installation begins with understanding the customer’s backup power needs and the available fuel source at the property. Whole-house standby generators provide automatic backup power for the entire home or business and operate on natural gas or propane in most residential applications. Larger commercial installations sometimes use diesel-fueled generators with on-site fuel storage. Smaller installations focused on critical circuits only may use portable generators with manual transfer switches or interlock systems. We discuss these options during the consultation phase so customers understand the tradeoffs between automatic and manual systems, whole-house and selected circuit coverage, and the various fuel options.

Generator sizing is one of the most important decisions in any installation because undersized generators cannot support the loads they need to power. Sizing calculations consider the specific loads that will run during outages including HVAC equipment, well pumps, water heaters, refrigeration, lighting, and any critical equipment. Residential whole-house generators typically range from 14kW to 26kW for average homes, with larger generators serving homes with significant electrical demand. Smaller generators at 7kW to 14kW work well for selected circuit installations where only critical loads need backup power. We perform sizing calculations during the estimating phase rather than guessing.

Generator placement requires attention to multiple considerations including manufacturer setback requirements, accessibility for service, fuel source proximity, and aesthetic preferences. Most manufacturers specify minimum distances from buildings, windows, doors, and combustible materials. Local code and zoning sometimes add additional placement restrictions. The generator needs accessible space around it for service work and proper airflow for cooling and exhaust. Fuel line routing affects placement choices when natural gas or propane fuel must reach the generator location. We coordinate placement decisions with customers based on practical considerations and any aesthetic preferences.

Transfer switch installation is integral to whole-house generator systems and provides the connection between the generator, the utility service, and the home’s electrical panel. Automatic transfer switches sense utility outage, signal the generator to start, and switch the load from utility to generator power within seconds of the outage. Manual transfer switches require the operator to start the generator and manually switch the load, which is the typical approach for portable generator setups. Service-rated transfer switches replace the main breaker function and may eliminate the need for a separate main panel disconnect. We install transfer switches that match the generator output and the home’s electrical service.

Fuel system work is a significant part of every standby generator installation. Natural gas connections require coordination with the gas utility or a licensed plumber for the gas line work. The gas line must be sized to deliver adequate fuel flow at peak generator load, which sometimes requires upsizing the service to support the generator demand. Propane installations require tank sizing, tank placement, and fuel line routing appropriate to the generator. We coordinate with fuel system contractors as needed during installation so all aspects of the project move forward together. The electrical and fuel sides of the installation must both be ready before commissioning.

Concrete pad or stable surface preparation is required for nearly all standby generator installations. Generators sit on concrete pads, composite pads, or other stable bases that prevent settling and provide proper drainage. The pad must be sized appropriately for the specific generator and placed in a level location with adequate clearance. We typically arrange pad work as part of complete installation projects, coordinating with concrete contractors or installing composite pads ourselves depending on project scope. The pad is one of those details that affects long-term generator reliability and warranty coverage.

Commissioning and testing complete every generator installation we perform. The generator is started, run under no-load conditions, then placed under load through the transfer switch to verify proper operation. Voltage, frequency, and current readings confirm the generator is delivering proper power to the loads. Automatic transfer switches are tested by simulating utility outage to verify proper sensing, generator startup, and load transfer. Manual transfer switches and interlocks are tested through their operation procedures. We walk customers through generator operation, maintenance requirements, and what to expect during actual outages. Edinson Electrical leaves every installation ready for use with the customer fully oriented to their new backup power system. Allentown customers benefit from installations that perform as expected when outages occur.

The Importance of a Licensed Electrician for Generator Installation in Allentown

Hiring a licensed electrician for generator installation in Allentown is essential because the work involves significant electrical equipment, fuel systems, and code requirements that DIY work cannot safely handle. Generator installation requires properly sized circuits, transfer switch installation, neutral handling appropriate to the specific generator type, and fuel system coordination. Mistakes in any of these areas can create fire hazards, equipment damage, or backfeed conditions that endanger utility workers during outages. Pennsylvania law requires licensing for this kind of work specifically because of the safety implications. Insurance considerations are particularly important for generator installations because of the high cost of the equipment and the consequences of improper installation. Manufacturer warranties on standby generators typically require licensed installation to remain valid. Permits cannot be pulled by unlicensed individuals, and inspections fail when work has been performed without proper credentials. Backfeed protection is a critical safety feature that depends on proper transfer switch installation to protect utility workers during outages. Edinson Electrical is fully licensed and insured in the State of Pennsylvania with extensive generator installation experience. Our lifetime craftsmanship warranty backs every installation we complete, and we provide the documentation customers need for warranty registration and insurance coverage.

Commonly Asked Generator Installation Questions

Generator installation is a significant investment that property owners typically research carefully before making a commitment. The questions below cover what customers across Allentown most often ask before scheduling generator installation.

Generator installation costs depend significantly on the generator size, the fuel system, the transfer switch configuration, and any related electrical work. Whole-house standby generator systems represent a meaningful investment that includes the generator itself, the automatic transfer switch, electrical connections, fuel system work, pad preparation, permit, and commissioning. Smaller portable generator interlock installations are much less expensive because they do not include the generator and use simpler transfer arrangements.

Several variables affect total project cost. Generator size drives a significant portion of the cost because larger generators cost more to purchase. Fuel system requirements vary considerably depending on whether natural gas, propane, or diesel will fuel the generator. Natural gas installations may require gas service upgrades to handle the generator demand. Propane installations require tank installation or upsizing of existing tanks. The distance from the panel to the generator location affects conduit and conductor costs. Long runs through finished spaces add to labor costs.

Optional features affect total project cost. Whole-house coverage costs more than essential circuits coverage because of the larger transfer switch and generator capacity required. Smart monitoring systems with mobile app connectivity add modest cost while providing useful features. Cold weather kits for generators installed in unheated locations add to base cost. We provide detailed written estimates that itemize all components so customers understand exactly what they are paying for. Financing through Synchrony helps make standby generator installation manageable on monthly payments. Edinson Electrical prices generator installations fairly and transparently. Allentown customers value the clear breakdown that supports informed decisions about their backup power investment.

A typical residential whole-house standby generator installation takes between two and four days from start to commissioning. The work includes generator placement, pad preparation, electrical connections, transfer switch installation, fuel system work, and commissioning. Coordination with fuel system contractors sometimes affects scheduling, particularly for natural gas connections that require utility coordination or for propane tank installations.

Portable generator interlock installations are much faster, typically completing within a single day. The work involves installing the interlock device on the main panel, installing an inlet box on the exterior of the building, and running conduit and cable between them. Some interlock installations also include adding circuits for specific equipment that should be supported during outages.

Inspection requirements affect the overall timeline because the installation cannot be put into use until inspection passes. Most jurisdictions require electrical inspection of the transfer switch and generator electrical connections. Gas piping inspections may also apply depending on the fuel system. We coordinate inspections proactively so projects move efficiently from installation to use. Edinson Electrical communicates expected timelines clearly so customers can plan around the work. Allentown customers value the predictable scheduling and efficient project completion. Most generator installations move smoothly from initial planning through final commissioning.

Generator sizing depends on what loads the generator needs to power during outages. Whole-house generators size to support the entire home’s electrical demand including HVAC, water heating, cooking, refrigeration, lighting, and any other loads. Most residential homes require generators in the 14kW to 26kW range for true whole-house coverage. Larger homes with significant electrical demand, electric heating, or multiple HVAC systems may need larger generators.

Selected circuit installations use smaller generators because they only need to power critical loads rather than the entire home. Critical loads typically include refrigeration, well pump or sump pump, heating system controls and blowers, a few lighting circuits, and outlets for charging electronics and small appliances. Generators in the 7kW to 14kW range often handle these selected loads adequately. The transfer switch in selected circuit installations only switches the critical circuits rather than the whole home.

Load calculation considers both running and starting loads. Many electrical loads draw significantly more current during startup than during normal operation. Well pumps, central air conditioners, and refrigerator compressors all have inrush currents that can be three to seven times the running current. The generator must handle these startup loads without dropping out, which sometimes requires upsizing beyond what running load calculations alone would suggest. We perform proper load calculations including startup considerations during the estimating phase. Edinson Electrical helps Allentown customers select generator sizes that actually meet their backup power needs. Right-sizing produces installations that perform reliably during outages.

Generator run time during outages depends entirely on the fuel source. Natural gas generators connected to the utility gas service can theoretically run indefinitely as long as natural gas service remains available. Natural gas service is typically more reliable than electric service during weather events because gas distribution is largely underground and less affected by storm damage. This makes natural gas generators excellent choices for extended outage support.

Propane generators run as long as the propane supply holds out. Typical residential propane tanks hold 250 gallons or 500 gallons of propane, with larger tanks available for properties planning extended outage support. A 20kW generator running at half load uses approximately 2.5 gallons per hour, meaning a 500-gallon tank could support roughly 200 hours of operation. Tank size and refill availability affect practical run time during extended outages. We help customers plan tank sizing based on their outage preparedness goals.

Diesel and gasoline generators have different fuel considerations. Diesel generators with on-site fuel tanks operate as long as fuel lasts, with tank refilling possible when needed. Gasoline portable generators have small fuel tanks that require frequent refilling, typically every few hours of operation. Gasoline storage for extended outages becomes complicated because gasoline degrades over time and presents fire risks in significant quantities. Most extended outage preparation uses natural gas or propane fuel sources rather than gasoline. Edinson Electrical helps Allentown customers plan fuel sources appropriate to their outage preparedness goals. The right fuel choice supports the specific resilience the customer needs.

Standby generators with automatic transfer switches turn on automatically within seconds of detecting utility outage. The transfer switch monitors utility power continuously and signals the generator to start when utility power is lost or drops below acceptable levels. The generator typically reaches operating speed within 10 to 30 seconds, at which point the transfer switch transfers the load from utility to generator power. The home or business experiences only a brief power interruption before backup power is restored. This automatic operation is the main advantage of standby generators compared to portable generators.

Portable generators require manual startup and manual transfer of loads. The operator must start the generator manually, connect it to the inlet box, and operate the transfer switch or interlock to power selected circuits. This manual process means the property remains without power until someone is available to start the generator. Manual operation is acceptable for many situations but less convenient than automatic standby generators.

Automatic systems also handle generator shutdown and load return automatically. When utility power is restored, the transfer switch verifies stable utility power for a brief period before transferring the load back to utility power. The generator then runs for a short cooldown period before shutting down. This automatic cycle ensures the generator runs only when needed and returns the home to utility power as soon as it is reliably available. Edinson Electrical installs automatic and manual generator systems based on customer preferences and budget. Allentown customers benefit from honest evaluation of which approach matches their actual needs.

Natural gas is the most common fuel for residential standby generators in areas with natural gas service. The advantages include continuous fuel supply through the utility connection, no fuel storage requirements at the property, and relatively clean burning fuel. The main limitation is that natural gas service must be available at the property and the gas line must be sized appropriately for the generator demand. Properties with natural gas service typically use natural gas generators when standby power is added.

Propane is the most common alternative when natural gas service is not available. Propane generators operate similarly to natural gas units but require on-site propane storage. Tank sizing depends on expected outage duration and refill arrangements with local propane suppliers. Properties already using propane for heating, water heating, or cooking may have existing tanks that can support generator use. Propane is widely available throughout the Lehigh Valley with reliable refill service from multiple suppliers.

Diesel and gasoline fuel options exist but are less common for residential standby generators. Diesel generators are typical in larger commercial and industrial applications but rarely used for residential standby installations. Gasoline-fueled standby generators have generally fallen out of favor because of fuel storage challenges and shorter equipment service life compared to natural gas and propane units. Portable generators typically use gasoline because of fuel availability for the limited duration of typical use. Edinson Electrical helps Allentown customers select fuel sources appropriate to their specific situations. The right fuel choice depends on what is available at the property and the customer’s preferences for fuel management.

Whole-house generators can power the entire home when properly sized for the actual electrical demand. The generator must be large enough to support all running loads simultaneously plus any startup loads that occur during operation. Whole-house systems use larger transfer switches that switch the entire main panel from utility to generator power. The home operates essentially normally during outages with all circuits available.

Achieving true whole-house coverage requires careful sizing calculations to ensure the generator can handle realistic load combinations. Loads that run simultaneously must be considered together rather than just summing maximum individual loads. Smart load management features on some generators automatically shed less critical loads when total demand approaches generator capacity, protecting against generator overload. These features can sometimes allow smaller generators to provide whole-house coverage by managing demand intelligently.

Partial-house coverage is sometimes a more economical choice than full whole-house coverage. Selected circuit installations protect only critical loads, allowing the use of smaller, less expensive generators. The transfer switch in these installations only switches selected circuits rather than the main panel. Customers using partial-house coverage often select circuits for refrigeration, heating, well pumps, sump pumps, and basic lighting and outlets. Cooking, electric water heating, electric vehicle charging, and large HVAC loads often remain on utility power only. Edinson Electrical helps Allentown customers think through coverage options based on actual outage preparedness needs and budget. The right scope produces good value without unnecessary upfront expense.

Standby generators require regular maintenance to operate reliably when needed. Manufacturers typically specify annual maintenance for residential standby generators, with more frequent service for generators that see heavy use. Annual service includes oil and filter changes, spark plug replacement at recommended intervals, battery testing and replacement as needed, and general inspection of mechanical and electrical systems. Skipping maintenance is a leading cause of generator failures during actual outages.

Self-tests are an important automatic feature on modern standby generators. The generator runs for a brief period each week or month to verify proper operation, exercise the engine, and identify any developing problems before they cause failures during actual outages. We program self-test schedules during installation based on manufacturer recommendations and customer preferences. The self-test typically runs the generator without transferring load, providing exercise without affecting the home’s electrical service.

Battery replacement is one of the most common maintenance items because the starter battery is critical for generator startup and degrades over time. Most generator batteries last three to five years before requiring replacement. Cold weather operation accelerates battery wear, making replacement intervals shorter in our climate. Other consumable items including air filters, oil filters, and spark plugs follow manufacturer-specified replacement schedules. Edinson Electrical provides maintenance service for generators we have installed, and we can also service generators installed by others. Allentown customers benefit from ongoing maintenance relationships that keep generators ready for the next outage. Regular service is the difference between generators that work when needed and generators that fail at the worst possible moment.
