Patent ID: 8570715

Claim:
A load center comprising: a circuit board; two power buses carried on the circuit board and each arranged for conductive connection to a respective one of two incoming power lines intended to feed the load center; conductive paths branching away from each power bus in conductive connection therewith respective branch circuit breaker mounting sites defined on the circuit board and each conductively linked to a corresponding one of the two power buses by a respective one of the conductive paths, each branch circuit breaker mounting site being arranged to engagingly receive a branch circuit breaker in a position placing said circuit breaker in electrically conductive connection with the respective conductive path; and current sensors mounted on the circuit board, each in association with a respective one of the conductive paths branching off from the power buses to provide an output responsive to current passing through said respective conductive path from the corresponding one of the two power buses to the respective branch circuit breaker mounting site; wherein the conductive paths comprise conductive branch traces on the circuit board between the power buses and the branch circuit breaker mounting sites, and the branch circuit breaker mounting sites are arranged in rows comprising two circuit breakers each, the two circuit breakers of each row connecting to a same one of the two power buses via branch traces found among different layers on the circuit board.
