Generator Interlock Kits

Generator Interlock Kits

A generator interlock kit is the lowest-cost way to back up your home with a portable generator. It mounts on your breaker panel cover so the main breaker and the generator breaker can never be on at the same time, which lets you power your home's circuits through a power inlet box without backfeeding the utility line.

Find the kit for your panel

Interlock kits are panel-specific. Match the kit to your panel brand and amperage, then check the main breaker style, which way it throws, and the spacing between the main and the first breaker against the photos and specs on each product page. We carry GenInterlock kits for:

  • Square D: QO and Homeline 150/200 amp, Homeline meter main, and vertical throw main panels
  • GE: 100 amp and 150/200 amp panels, horizontal and vertical throw
  • Eaton Cutler Hammer: CH, BR, and plug-on neutral 150/200 amp panels
  • Siemens and Murray: 100 amp and 150/200 amp panels
  • Siemens, ITE, and Gould: 150/200 amp panels with a vertical throw main
  • Bryant: Type BJ 150/200 amp panels

Not sure which one fits? Send us a photo of your panel at 888-855-7286 and we will confirm the fit before you order.

What else you need

An interlock kit works with a double-pole generator breaker that matches your panel, a power inlet box and generator cord, and a generator with a 30 or 50 amp outlet. Shop generators, or compare an interlock with a transfer switch in our guide to interlock kits vs transfer switches. Installation should be done by a licensed electrician where your local code requires it.
