This system is a security mechanism designed to be used with residential electrical panels, particularly these manufactured by Cutler-Hammer using the “CH” collection 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 means 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 could be switched on to energy pre-selected circuits throughout the house.
The significance of this specific setup lies in stopping backfeeding, a harmful scenario the place generator energy is shipped again onto the utility grid. Backfeeding poses a major electrocution threat to utility staff making an attempt to revive energy and also can 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 supplies a cheap resolution for whole-house or partial-house energy throughout emergencies, avoiding the necessity for a dearer computerized switch change. The idea of interlock kits has advanced over time to satisfy electrical security requirements and supply owners with a safe option to make the most of generator energy.
