Patent ID: 8554388

Claim:
An electrical power management system for electrically coupling between a separate, conventional main power load panel having a plurality of circuit breakers and a plurality of power circuits controlled by the plurality of circuit breakers, the system comprising: a power intervening panel positioned between a conventional main power load panel having a plurality of conventional circuit breakers and a plurality of power circuits controlled by the plurality of circuit breakers comprising: a low voltage power supply having a low voltage output electrically coupled to a low voltage circuit, a low voltage common and a power load input; a power module array having a plurality of power contactor modules wherein each of the plurality of power contactor modules has (i) a power contactor with a power load input configured for electrically coupling at least one circuit breaker of the plurality of circuit breakers of the separate, conventional main power load panel to an electrical circuit controlled by the circuit breaker; (ii) a power load output electrically coupled to the electrical circuit; and (iii) a low voltage switch operably connected to the power contactor; wherein the power contactor is switchable between a normally closed position and an open position and wherein the power contactor is switched to the open position only when the low voltage switch receives low voltage power and returns to the normally closed position when the low voltage power to the low voltage switch is interrupted; a low voltage signal relay module having a plurality of signal couplings wherein a primary coupling is a low voltage signal output connected to the low voltage power supply for transmitting a low voltage output signal to a direct digital controller and wherein a secondary coupling is a low voltage signal input for receiving the low voltage output signal from the direct digital controller, the secondary coupling being electrically coupled to the low voltage switch of one of the plurality of power contactor modules; and an intervening panel enclosure containing the low voltage power supply, the power module array and the low voltage signal relay module; and a direct digital controller having a low voltage controller input electrically coupled to the low voltage signal relay module, a low voltage controller output switchable between an on mode and an off mode and electrically coupled to at least one of the plurality of power contactor modules of the power module array.
