Abstract
A wire cable attachment adapter unit is secured to the top or bottom ends of a circuit breaker or electric switch enclosure to provide strain relief to the electrical power distribution cables that connect with the circuit breakers or switches arranged within the enclosure. The cable support adapter includes a plurality of integrally-formed bulkheads projecting from a support base with upstanding side arms having serrated outer surfaces and separately formed U-shaped clamps having striations formed on the inner legs thereof. The U-shaped clamps are positioned over the side arms to form a cable-receiving channel. After electrical connections are made within the enclosure, the U-shaped clamps are forced against the side arms to fixedly trap the cables within the chamber.
