"Kenny arrived at my home to install a light switch and back patio light that was non existent at the time. Kenny was on time and very professional. I had purchased a patio light before the installation and had to return to work and left Kenny to do his work. Kenny called me and told me that the light I purchased did not have the brackets that it should have had. Kenny took my light back to Lowes and brought back a new one and installed my light. I arrived home to my new light and switch and he cleaned up the area as if no one was even there. I will use Bruton electric again! Great Job!"

"I have dealt with a lot of contractors. John from Elite Electrical actually shows up (and on time), is respectful, personable, and best of all he knows everything about his trade and did an AMAZING job inspecting and explaining. He was very clear about what needed to happen and pricing for all options. A simple generator outlet turned into a whole panel upgrade, but the original panel was hazardous and he showed me exactly why. He suggested and did not push extra. I would definitely refer and re-hire for more projects."

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.

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. 

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. 

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 most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home generators. A permit for a generator usually costs between $50 and $250, depending on where you live. Your electrician or certified generator installer will usually pull the permit for you—and might be required to do so by your building department—but you’ll be on the hook for the cost of the permit. You should ask your installer before agreeing to any work if they will pull the necessary permits for your project.
