A '''generator interlock kit''' (or just the ORIGINAL '''interlock kit''') is a device designed to allow safe powering of a home by a [[engine-generator|portable generator]] during a [[power outage]]. It is a less-expensive alternative to purchasing and installing a dedicated [[transfer switch]]. The kit achieves the same function by adding an external interlock onto an existing breaker panel that allows the main breaker to be turned on ''or'' one designated load breaker to be turned on, but not both at the same time. The interlocked load breaker is repurposed as the "backfeed" breaker, and a generator is connected to it (wired directly or through a power inlet).

Under normal conditions, the main breaker is on, accepting power from the external mains into the panel, and the backfeed breaker is off, isolating the generator. The external mains feeds the panel, but the panel cannot [[backfeeding|backfeed]] the generator. [[Backfeeding]] the generator should never be done, because it serves no purpose and risks damaging the generator.
