Abstract
An industrial-rated circuit breaker line and load terminal lug and connector for connection with the power distribution line and load cables also includes a receptacle that allows connection with an auxiliary device for load indication and voltage metering. The receptacle is in the form of an insulative sleeve arranged around a metal contact blade in electric circuit with the line and load lugs. Electrical connection with the line and load cables and the auxiliary device occurs when the combined terminal lug and connectors are connected with the power distribution line and load cables.
