"I could not ask for a better electrician than Noah Parker. He has come through for me big-time on more than one occasion. Noah installed my generator & showed me how to use it; diligently diagnosed & fixed complex electrical problems in my older mobile home; & even fixed my lawnmower! Not only is Noah an expert at his craft. He is utterly kind, patient, trustworthy, fair, & decent. As a clueless first-time homeowner, I am SO grateful for Noah. I highly recommend him."

"I actually ended up doing the installation myself b/c I ended up with more time than I thought I would have before the new year. However, Wescott Electric was very prompt, and professional in their response to my request for a quote. I will definitely call Wescott Electric in the future for any project I need help with."

Generator Install questions, answered by experts

Many services include assembling the unit and securing it in the window. Confirm with your provider.

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. 

Generators are safe to use as long as they are installed and operated correctly according to the manufacturer's recommendations. The most critical safety tips are to never use a portable or fuel-powered generator inside an enclosed space due to the risk of lethal carbon monoxide poisoning; always operate it outdoors where fumes can dissipate away from your home. Additionally, never attempt to connect a generator to your home’s electrical panel yourself—hire a professional to ensure the setup meets safety standards. Finally, avoid overloading the generator by not connecting more appliances than it is rated for, as this can damage your equipment or cause a fire.

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.
