Generator Installation in Philadelphia

Certified Master Electricians for Residential & Commercial Generator Projects

When the power goes out, the quality of your generator installation determines what happens next. A-1 Electric has been handling complex electrical work for Philadelphia homes and businesses since 1955, when founder William H. Greenage Jr. became one of Pennsylvania’s first licensed electricians. His son, Thomas J. Greenage, leads the firm today with the same standards William built. Our team of certified master electricians, inspectors, and underwriters brings over 70 collective years of electrical service experience to every project. If you're interested in enhancing your energy security with a generator, don't hesitate to contact us.

Standby vs. Portable Generators: What Philadelphia Property Owners Should Know

Standby generators are permanently installed outside of your building, hardwired into your electrical panel, and connected to an automatic transfer switch. The transfer switch monitors utility power and starts the generator automatically during an outage, typically within seconds, then transfers back when utility power returns. Standby units run on natural gas or liquid propane, so there’s no gasoline to store or haul.

Portable generators provide temporary backup power but require manual setup and refueling, making them better suited for short outages and limited power needs. 

For residential clients, standby generator sizing follows a load assessment of essential circuits. Commercial and industrial installations involve higher load demands, more complex transfer switch configurations, and code compliance requirements specific to the facility type. Standby units should be installed outside or in properly ventilated enclosures because of carbon monoxide risk.

The Generator Installation Process

A thorough installation starts before any equipment arrives. A-1 Electric conducts an on-site assessment to evaluate your electrical load requirements, fuel source options, and site conditions. Appointments include a confirmed time window and day-of updates, so you know exactly when to expect us.

Here are more details about what you can count on:

  • Electrical load assessment to determine which circuits require backup power and size the generator accordingly
  • Site preparation, including a concrete pad or surface mounting as required
  • Fuel line connection to your natural gas supply or propane tank
  • Electrical panel integration and automatic transfer switch installation
  • System testing under load conditions before the project is considered complete

Philadelphia generator installations require a permit from the city’s permitting authority. Pulling the correct permits and meeting Pennsylvania electrical code aren’t optional steps; they’re what protect your property and your insurance coverage. 

A-1 Electric’s accreditation through the Commonwealth, the Department of Labor and Industry, and local Authorities Having Jurisdiction means we understand the compliance environment here. After installation, an independent third-party inspection can issue the certificate of compliance confirming the work meets code.

What Maintenance Does a Standby Generator Require?

Our Standards

Before inspections were legally required, our founder was already calling in underwriters to verify his own work. That standard has never changed.

Frequently Asked Questions

Do I Need an Electrical Inspection After Generator Repair?

It depends on the scope of work. Repairs involving the transfer switch, panel wiring, or electrical reconnection typically require a licensed electrician and may trigger an inspection before your utility restores power. An accredited third-party agency like A-1 Electric can perform that inspection, but not on the same project where we performed the repair work. Contact us, and we can help clarify what your situation requires.

What Generator Problems Require a Licensed Electrician Rather than a General Repair Technician?

Any work on the transfer switch, wiring between the generator and the main panel, voltage systems, or panel integration falls within the licensed electrician's scope under applicable electrical codes. 

General repair technicians aren’t qualified for this work, and unlicensed repairs can void warranties and create liability. A-1 Electric’s team consists entirely of certified master electricians.

Does A-1 Electric Repair Commercial & Industrial Generators?

Yes. We serve residential, commercial, and industrial clients throughout Philadelphia. Commercial and industrial generators carry higher-capacity demands and more complex electrical integration than residential standby units, and our certified master electricians are licensed and experienced across all three project categories.
