ABSTRACT:
An apparatus for detecting the power state of a circuit breaker switch is disclosed. The apparatus comprises a detector circuit, a processor and an indicator. The processor is coupled to the detector circuit. The indicator is coupled to the processor. In operation, the detector circuit senses an electronic signal at the circuit breaker switch and transmits a signal to the processor. The processor then transmits a signal to the indicator indicating the power state and location of the circuit breaker switch.
