Hello, I'm Greg Avila owner of Avila Electric, a family-owned small business here in the upstate. I've been a journeyman electrician for 10-15 years and on the management side of electrical and general construction for another 10 years. I've worked in a variety of settings from residential homes to apartments complexes to state prisons. Everday is different in my line of work, sometimes I'm chasing my tail trying to find a lose neutral, while other days I'm installing an electrical panel for a tiny home. My family and I moved to Piedmont about two years ago and have been enjoying getting to know the upstate's beautiful natural resources and charming cities. I look forward to meeting you and working with you on your next electrical project.

"Great. Everything went well i would recommend him any time."

Generator Install questions, answered by experts

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

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.

As long as they have enough fuel, whole-house generators can run for weeks at a time (400 to 500 hours) without suffering too much wear and tear. However, this type of extensive use isn’t ideal if you want to extend the life of your generator.

Two important points. First, some generators may need you to periodically check oil levels every day or so and refill as necessary for safe operation. Second, if your generator uses a fuel tank, keep it regularly full so it doesn’t suddenly shut off. Many backup generators can run through a full tank in a day when they are powering large portions of a home.

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