Facilities can significantly reduce energy costs by removing their AVL systems from the grid. Since there is no way to simply unplug everything, facilities resort to using standard circuit breakers as the on/off switch to power down their equipment at the source. However, that option isn’t recommended, and in the U.S., only specific breakers are listed to be used as switches. The best solution is to specify and install a power control system designed to power and protect AVL at the circuit level.
