ABSTRACT:
An interlock arrangement is provided between adjoining circuit breaker compartments by the addition of a contact arm operated interlock to circuit breakers which contain trip arm operated interlocks. The contact arm interlock comprises a paddle mounted on the rear surface of each of the adjoining breakers for sensing the condition of the contacts in one breaker and for interreacting with the trip arm interlock mechanism to trip the breaker when an attempt is made to close the first breaker contacts while the adjoining breaker contacts are closed. A stop lever mounted in the first breaker compartment interconnects with a similar lever mounted in the compartment of the adjoining breaker to prevent the first breaker contacts from being closed while the adjoining breaker contacts are closed. The compartment interlock arrangement finds utility when one of the interconnected circuit breakers connects with a utility power source and the other circuit breaker connects with an auxiliary generator.
