Ready to Put This Into Action?

The guide shows you what your generator can do. An inlet and interlock kit makes it actually happen, a safe, permanent, code-compliant connection from your portable generator to your home's breaker panel. No extension cords. Works every outage.

The quick fix

Extension Cords

Cheap, but risky
  • Cannot power hardwired circuits like your furnace, well pump, or lights
  • Fire and carbon-monoxide risk
  • Not code-compliant, and you set it up from scratch every outage
Recommended

Generator Inlet + Interlock

$1,197 to $1,497 all-in
  • Safe, permanent, permitted, and inspected
  • Powers your essential circuits through your panel
  • Works with the generator you already own, done in one day
The big-ticket option

Whole-Home Standby

$12,000 to $20,000 installed
  • Fully automatic, but a major expense
  • Often a months-long waitlist
  • More system than a portable-generator backup plan calls for

When you already own the generator, the inlet and interlock is the setup I usually recommend: the safety and permanence of a built-in system, using the generator you have.
