"Lemus Electrical was very responsive when we had a three-day outage. A technician came the same day I called, and came back one day later with 3 others to install a new electrical panel - which had been ruined by a transformer blowout. They were very professional, did very good work, and were cheerful about it all. I will definitely call them again, the next time we need electrical work!"

"Kevin Williams was sent to repair problems created by another electrician hired by Kitchen Saver during an expansive kitchen re-face and cabinet installation. Among other things, he re-located an unsightly transformer that had been previously secured to the inside of the first shelf of a main kitchen cabinet to a lower cabinet out of sight. Voila! Then, he re-routed unsightly wiring previously clamped to the far corner of a glass display cabinet so that it was out of sight. These were difficult puzzles to solve, as the new cabinets had already been installed and there was no longer easy access. Kevin was friendly, professional, and experienced! Great job!"

Generator Install questions, answered by experts

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.

In many cases, you’ll need a permit or basic inspection to install one of these large generators. Since they include significant alterations to your home electrical system and many produce exhaust fumes, local governments often require jumping through a few hoops for general safety purposes. Your installer may be able to help you with these permits.

No, this is extremely dangerous, often illegal, and you should never attempt it. If you connect your generator to your home without a transfer switch, the generated power can backfeed, essentially flowing back into the utility lines. Backfeeding exposes a significant threat of fatalities or harm to you and utility personnel, in addition to jeopardizing the structural integrity of your home.
