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 way of 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 might be switched on to energy pre-selected circuits throughout the residence.
The significance of this specific setup lies in stopping backfeeding, a harmful state of affairs the place generator energy is shipped again onto the utility grid. Backfeeding poses a big electrocution threat to utility employees trying to revive energy and may also harm gear. Putting in this specified element provides a safer and extra dependable methodology of generator connection in comparison with extension cords operating on to home equipment. Moreover, it gives a cheap resolution for whole-house or partial-house energy throughout emergencies, avoiding the necessity for a dearer automated switch swap. The idea of interlock kits has developed over time to satisfy electrical security requirements and supply householders with a safe technique to make the most of generator energy.
