Method of forming signal processor module for ground fault circuit breaker

摘要

The neutral excitation and differential current transformers of a ground fault circuit breaker are arranged for automated assembly onto the signal processor circuit board to complete the signal processor module prior to insertion within the ground fault circuit breaker housing. Electrical interconnection between the transformers is made by a unitary conducting strap having means therein for receiving the circuit neutral conductor. The completely assembled signal processor module is connected with the circuit breaker components by means of a single wire.
