Abstract
Embodiments of the invention relate to automated three phase power monitoring systems. Embodiments of the invention include a zero crossing activated switch having an overload condition signal input that is electrically connected to a signal output terminal. The zero crossing activated switch prohibits conduction of the overload condition signal to a neutral ground RMS reactive breaker control mechanism until the zero crossing activated switch determines that at least one of three alternating currents crosses zero relative to a neutral signal.
