  • Panel board to circuit breaker positive retention interlock
    Patent number: 9564280
    Abstract: An interlock assembly for a circuit breaker prevents inadvertent installation or removal of the circuit breaker from a circuit breaker panel while current is flowing. The interlock assembly cooperates with the circuit breaker panel to physically prevent the circuit breaker from being inserted into the circuit breaker panel until the circuit breaker is put into a tripped state. Likewise, the interlock assembly cooperates with the circuit breaker panel to physically prevent the circuit breaker from being taken out of the circuit breaker panel until the circuit breaker is put into a tripped state. This ensures that the circuit breaker will not be inadvertently installed or removed from the circuit breaker panel while current can immediately flow or is flowing through the circuit breaker.
