Generator Inlets & Interlock Kits

A generator inlet with an interlock kit lets you safely connect a portable generator directly to your panel with no extension cords running through windows and no risk of backfeed into the grid. It's one of the most practical and affordable ways to prepare for an outage, and it's a straightforward install in most homes.

Why a proper hook up matters:

  • Plugging a generator into an outlet directly is dangerous and against code

  • Backfeed can injure utility workers and damage your home's wiring

  • An interlock kit lets you power specific circuits safely and legally

  • Installation is typically completed in a single visit

30 & 50 Amp Generator Hookups

Depending on your generator's size and what you want it to power, you'll need either a 30 or 50 amp hookup. We'll walk you through which setup matches your generator and your home's needs.

Whole-Home Standby Generator Preparation

Thinking bigger? We prepare homes for whole-home standby generators — handling the electrical side so your system is ready to go when the generator is installed. This includes panel evaluation, critical circuit identification, and ensuring your setup can support automatic backup power.
