ABSTRACT:
Molded plastic bus covers are attached to the ends of a pair of molded case circuit breakers to isolate the circuit breakers from an electrical enclosure as well as to isolate between the circuit breakers themselves when connected within the enclosure in a double-branch configuration. Molded plastic lug covers are attached to the opposite ends of a molded case circuit breaker when the circuit breaker lugs are connected to power distribution cables to electrically isolate the power cables and the circuit breaker lugs.
