Q: We recently had a big storm hit New England. Once again, I wish I had a backup generator system installed at my home. After going through my second prolonged power outage in the last few years, this spring I’m going to get the project started. Whom do I contact first and what can I expect to happen during a power failure once my generator is installed?

Andy, New England

A: I want to clarify that the type of generator you’re asking about is called a “standby” generator system. Residential standby generators run on natural or propane gas and are permanently hooked up to a home as an automatic system.

These can provide emergency power to a home for days or even weeks at a time while one waits for utility power to be restored.

A standby-generator system needs to be professionally installed, and all required permits need to be pulled.

Start with a licensed and insured standby-generator installer in your area. You can also contact a certified distributor, who can usually set you up with an installer.

The first visit should include walking the property to check out equipment location and the electrical load to determine the correct generator size. Ask for an estimate in writing, since the systems can be expensive.

What should you expect from a standby system? When power is lost, an automatic transfer switch starts the system, and in about 10 seconds or so generator power comes on. Once electricity is restored, the standby system shuts down.
