Generator Installation in Connecticut: FAQs

Common questions about standby generators for Connecticut homeowners.

What size standby generator does my Connecticut home need?
For essential loads only - fridge, furnace, sump pump, lights, internet - a 10-14 kW air-cooled standby is usually enough. For whole-home backup including central A/C and electric appliances, you typically need 18-22 kW air-cooled or a liquid-cooled unit. We run a load calculation during the estimate to size your generator correctly.
What generator brands does West Electric install?
We install Generac, Kohler, Cummins, Briggs & Stratton, and Champion standby generators. We have the most experience with Generac and Kohler - Connecticut's dominant brands - but we can install whichever brand fits your needs.
How much does whole-home standby generator installation cost in Connecticut?
Most installed prices run $7,000 to $15,000 or more for residential standby systems. Cost depends on generator size, fuel type (natural gas vs propane), transfer switch type (manual vs automatic), and any panel or fuel-line work. We quote firm prices after a site visit.
Do I need a permit for a generator in Connecticut?
Yes. CT requires an electrical permit, a building or zoning permit for the generator pad, and typically a gas piping permit if connecting to natural gas. West Electric pulls all permits and handles inspection. Many towns also have setback rules from property lines and dwellings that we plan around.
How often does a standby generator need maintenance?
Most manufacturers (Generac, Kohler, Cummins) recommend annual maintenance - oil and filter change, battery check, and exercise-cycle inspection. We offer maintenance contracts. Most units also run a self-test weekly to confirm they will start when you need them.
Will the generator turn on automatically during a Connecticut outage?
Yes - with an automatic transfer switch (ATS), which we include with all whole-home standby installs. The ATS detects loss of utility power, signals the generator to start, and transfers your home to generator power within 10-30 seconds. When utility power returns, it transfers back automatically.
