Abstract:
A safety system for an electrical distribution system that insures voltage sufficient to power user devices interfaced to the distribution system is only provided when the distribution system is fully functional and not damaged. The safety system comprises the power distribution system, a power control box, and a circuit activator signal generator in electrical communication with the power distribution system. The power control box is electrically coupled to the power distribution system and is operable to generate a first signal of a first voltage and a second signal of a higher second voltage. The power control box communicates the first signal to the circuit activator signal generator. Upon receipt of the first signal, the circuit activator signal generator generates a third signal having a third voltage that is lower than the second voltage and communicates the third signal to the power control box. The power control box provides the second signal to the power distribution system upon receipt of the third signal and does not provide the second signal if the third signal is not received.
