Generator Install questions, 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.

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.

Yes, whole-house generators run constantly for extended periods. Whole-house generators can run for longer periods of time than portable generators, but be careful. First, they may need regular applications of engine oil (as frequently as daily), depending on the engine design. Second, running constantly for several days will increase the wear and tear on the generator and shorten its lifespan.

The cost to install a whole-house generator averages at $5,200, but costs can range from $1,500 to $8,900, depending on the type and size of the generator, and the labor required to install it. To find the best deal while still ensuring the unit meets all the needs of your household, hire an electrician to calculate the electrical load of your must-have appliances and electronics beforehand so you don’t pay for more power than you need. As always, be sure to get at least three quotes to find the ideal fit for your needs and budget.

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.
