Standby generator installation

What you are buying

A standby system has three main parts. The generator itself sits on a pad outside. An automatic transfer switch connects it to your electrical panel. A fuel line connects it to your gas meter or a propane tank. Together they watch the utility power around the clock and take over when it stops.

The unit runs a short self-test on a schedule, often weekly, so you find out about problems before a storm rather than during one. Most models also send alerts to a phone app or a display panel if something needs attention.

How the installation usually goes

It all starts with a visit to the house. The installer checks the panel and service size, the gas meter or propane options, and where code and the manufacturer allow the unit to sit. You then get a written quote. After you sign, the installer orders equipment and pulls permits. The install itself usually covers the pad, the transfer switch, the wire and fuel runs and a start-up test, followed by an inspection.

• Load calculation that matches the generator size to what you want to run
• Transfer switch sized for your electrical service
• Pad or base set level, which can take extra work on a slope
• Fuel connection by a qualified gas fitter, plus any meter upgrade the utility requires
• Permit and inspection handled by the installer
• Walkthrough of the controls, alerts and maintenance schedule

Hills, old houses and the river

Croton and the river hamlets north of it are full of houses built on slopes, often close to the street. Finding a level spot that meets clearance and setback rules can take creativity. Older houses can also have tight basements, older panels and long distances between the panel and the best outdoor location. None of this rules out a generator. It does mean quotes vary, and a careful site visit is worth more than a phone estimate.

If any part of your property sits low near the river or a stream, ask the installer about raising the pad so the generator stays above standing water.

Comparing quotes

Line the quotes up side by side. Each should name the generator model and kilowatt rating, the transfer switch, the gas or propane work, the pad, and who pulls the permit and meets the inspector. Ask what the manufacturer warranty covers, whether the installer registers it, and who will service the unit afterward. A quote that leaves out the fuel work or the permit only looks cheaper.

Living with a standby generator

Once it is in, a standby generator mostly stays out of sight. You will hear it run its exercise cycle, see the status light or app, and book a service visit about once a year. During an outage, the house lights flicker off for a few seconds and then come back on generator power. When the grid returns, there is another short blink as the switch hands you back. Keep the area around the enclosure clear of snow, leaves and plantings, and keep carbon monoxide alarms working on every floor of the house.
