  • Circuit monitor for plural electrical switching apparatus
    Patent number: 5754113
    Abstract: A monitoring apparatus includes sensors for interconnection with the load output terminal of a corresponding circuit breaker. The sensors sense the closed and open states of the corresponding circuit breakers and produce closure signals at outputs. The sensor outputs are interconnected in series to produce a combined closure signal for all of the circuit breakers. An indicating circuit interconnected with the combined closure signal outputs a signal, such as a relay contact or an audible, visual, or digital signal, to indicate the combined closure status of the circuit breakers.
