Abstract:
1. A circuit breaker preventing electrical connection between a power line source and a load when a neutral rail is disconnected from the circuit breaker, the circuit breaker comprising: a line connector; a load connector; a neutral plug-on line connector; a trip mechanism having an on position allowing electrical connection between the line connector and the load connector, a tripped position interrupting electrical connection between the line connector and the load connector in response to detection of at least one fault condition, and an off position which is required before resetting the trip mechanism to the on position; a trip link coupled to the trip mechanism, the trip link having a first position preventing the trip mechanism from being reset to the on position and a second position allowing the trip mechanism to be reset to the on position; and a neutral lock mechanism coupled to the neutral plug-on line connector, the neutral lock mechanism including a spring that retains the trip link in the first position when the neutral rail is disconnected from the neutral plug-on line connector, the neutral lock mechanism actuating the spring when the neutral rail is connected to the neutral plug-on line connector allowing the trip link to move to the second position.
