  • Patent number: 4973937
    Abstract: A multipurpose electrical shunt, formed from an integral body of material, includes a first and second electrical connectors spaced apart for mating with a first terminal of a main circuit breaker and a first terminal of a branch circuit breaker. The shunt further includes an electrically resistive material integrally connected to the first and second electrical connectors for providing a voltage drop thereacross proportional to the current flowing therethrough and first and second output terminals extending beyond the resistive material for connection to a current sensing means such as an electrical meter. The shunt provides a current carrying conductor connecting a main circuit breaker to the branch circuit breaker and further provides sensing of the current flow between the main circuit breaker and the branch circuit breaker.
