"I had my whole house rewired. The job was done right and efficiently, and customer service was always great. I had no problem getting in touch with the company with any questions. The workers were wonderful; always helpful and didn’t mind me asking any questions. I heard no complaints; the weather was hot, but they got the job done in the estimated timeframe. I commend them."

"Provision Electric did an amazing job replacing our outdoor entryway light. He was incredibly flexible when Amazon delayed delivery of the fixture and still worked with our schedule. Installation was quick and efficient, and he even went above and beyond by running to get light bulbs when I completely forgot to buy them. Excellent service, professional, and truly cared about making sure everything was perfect. We’ll definitely be using Provision Electric again for any future electrical needs!"

Generator Install FAQs, answered by experts

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

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.

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window.
