"Work was well done, and they thought about how to best install the outlets to serve the needed purpose. Installation was quick and professional, they also cleaned up after themselves. I will use Thundercolt Electric for future electrical needs."

"I had finally broke down and bought a generator. When I called one of the big guys they said they would show up at a certain time. Lets just say they did not. When I called to their office all I got was the run around. I was referred to James Griffin Electric by a friend and when I called I was surprised the owner actually answered. He was able to get out there very promptly and got me going. I will definitely be using him again and referring him in the future."

Generator Install questions, answered by experts

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a whole-home generator instead.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.
