Abstract: A printed circuit board (PCB) is provided and includes a plurality of edge connectors, a pin connector, and a plurality of electrical lines each electrically connecting one of the plurality of edge connectors to the pin connector. The plurality of edge connectors are positioned on the PCB to enable the plurality of edge connectors to interface with respective connectors of a plurality of configurations of circuit breakers. The configurations may include a configuration including a first type of circuit breaker and a configuration including a second type of circuit breaker. The first and second types of circuit breakers may be 1-63 ampere (A) and 80-125A circuit breakers or 80-125A and 200A circuit breakers, or may be any of a variety of other types.
