"Very happy with my experience with Mr. Electric. I have used them to put in my whole house generator. They were great. Sam Stone is awesome. He showed up on time and upgraded our panel box. I found him to be very professional and knowledgeable. I would highly recommend this company and Sam Stone for all electrical services"

"Mr. Bailey assembled the fan, installed it properly and quickly. He took the old fan to the curb so that I wouldn't have to. The cost (211.50) was a bit more than I had anticipated but the value for the service was reasonable. I can wholeheartedly recommend Lighthouse Electrical Service."

"Doug is a master electrician and has completed not only a panel upgrade for us but several other electrical projects. He’s knowledgeable, reliable, and easy to work with. What really stands out is that he genuinely cares about the quality and appearance of the finished product—not just getting the job done, but making sure it looks great too. Highly recommend and will continue to call True Line electric for my electrical needs."

Generator Install questions, answered by experts

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

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

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.

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.
