This gadget 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 by way of a mechanical slide that bodily interlocks the generator breaker and the primary breaker, permitting just one to be within the “on” place at any given time. For instance, if utility energy is misplaced, the primary breaker is switched off, after which the generator breaker may be switched on to energy pre-selected circuits inside the residence.
The significance of this explicit setup lies in stopping backfeeding, a harmful state of affairs the place generator energy is distributed again onto the utility grid. Backfeeding poses a major electrocution threat to utility staff trying to revive energy and may also injury gear. Putting in this specified part provides a safer and extra dependable technique of generator connection in comparison with extension cords operating on to home equipment. Moreover, it gives an economical answer for whole-house or partial-house energy throughout emergencies, avoiding the necessity for a costlier computerized switch swap. The idea of interlock kits has advanced over time to satisfy electrical security requirements and supply owners with a safe solution to make the most of generator energy.
