This machine is a security mechanism designed to be used with residential electrical panels, particularly these manufactured by Cutler-Hammer using the “CH” sequence breakers. It ensures {that a} generator can safely provide energy to a house throughout a utility outage by stopping simultaneous connection of the generator and the utility energy grid. That is achieved via a mechanical slide that bodily interlocks the generator breaker and the principle breaker, permitting just one to be within the “on” place at any given time. For instance, if utility energy is misplaced, the principle breaker is switched off, after which the generator breaker will be switched on to energy pre-selected circuits inside the residence.
The significance of this specific setup lies in stopping backfeeding, a harmful scenario the place generator energy is distributed again onto the utility grid. Backfeeding poses a major electrocution danger to utility staff trying to revive energy and also can harm tools. Putting in this specified element presents a safer and extra dependable methodology of generator connection in comparison with extension cords operating on to home equipment. Moreover, it offers an economical resolution for whole-house or partial-house energy throughout emergencies, avoiding the necessity for a costlier computerized switch change. The idea of interlock kits has advanced over time to satisfy electrical security requirements and supply householders with a safe solution to make the most of generator energy.
