Generator hookups & transfer switches

When an ice storm takes the lines down, you should be able to plug in the generator, flip a breaker or two and get the furnace, well pump and fridge running again. No cords through the window and no dangerous backfeeding.

The two ways to do it right

  • Interlock kit + inlet box. The most popular choice for portable generators. A mechanical interlock on your panel makes it impossible to have the main breaker and the generator breaker on at the same time. A 30 or 50 amp inlet box outside means you plug in one cord. You choose which circuits to run.
  • Transfer switch. A separate switch that feeds a set of essential circuits. It's a good fit when the panel can't take an interlock, or when you want specific circuits pre-wired.
Please don't backfeed with a double-male "suicide cord." It can energize the utility line and injure the line crew working to restore your power. It can also burn up your generator when the power comes back on.

What a typical install includes

A recent job in Nichols is a good example: an interlock kit on the main panel, a 50 amp generator breaker with a hold-down kit, a 6/3 feed out to a 50 amp inlet, plus the permit and inspection. The homeowner plugs in, turns the main off, turns the generator breaker on, and runs what they need.

Already bought the kit or inlet? That's fine. Tell Eric what you have and the quote will reflect it.

Sizing it to your generator

Bring the make and model, or a photo of the generator's outlet panel. It decides whether you need a 30A (L14-30) or 50A (14-50 / CS6365) inlet. Eric will also tell you honestly what the generator can run at the same time, like the well pump, furnace blower, fridge and a few lights.

How it's priced

Flat price in writing, with materials, permit and inspection listed. Inspection fees are passed through at actual cost.
