"Carlos is a PRO. Came out installed a new 200 amp electrical panel, conduit protected 200 amp line in, full bonding and grounding system, as well as ran a line and installed a generator interlock kit. He was thorough in showing me how to operate everything, the craftsmanship of his work was next level, everything up and running in a timely manner, and the cost was great. 10/10 would recommend for any and all electrical needs."

"The quality of work was poor, some of switches do not work, some of the electric outlet did not work. I contacted the service provider but never heard back from them. The service provider did the bare minimum to complete the job. The quality of the hardware installed is as bad as it can be. It would have been nice if he gave us a few options, showed us what he was going to install but he did not. We got what he chose for us.

Generator Install FAQs, answered by experts

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

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. 

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

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.
