Generac Generator Installation, Service & Maintenance in Kenilworth, NJ

When the power goes out, everything in a New Jersey home stops — the refrigerator, the heat, the medical equipment, the lights. A standby generator changes that by starting automatically and running your home on its own power until the grid recovers. If you are considering whole-home generator installation in Kenilworth NJ, this page explains exactly what we do and who we are.

Standby generator questions from Kenilworth homeowners

Does the generator need its own gas shutoff?

The fuel installation has to include the shutoff arrangements required by the adopted fuel-gas code and by the installation instructions. The valve must be positioned where it is accessible, both for servicing and for isolating the machine in an emergency.

What is a service-entrance-rated transfer switch?

One that is listed for use as service equipment when installed in the appropriate configuration. These are commonly used for whole-house systems, where the transfer switch becomes part of the home's service arrangement rather than sitting downstream of it.

What size standby generator does a Kenilworth home need?

The correct size is decided by the electrical loads the generator is expected to run, not by the square footage of the house. Central air, heat pumps, electric heat, well and sump pumps, refrigerators and freezers, electric ranges and dryers, pool equipment and EV chargers all count. Where a load is connected automatically, the generator either has the capacity for it or an approved load-management system controls it.
