Distribution Circuit Breaker Insertion Procedures
1. When inserting the distribution circuit breakers into their respective terminals, both spades may not fully seat in the female terminals and the auxiliary alarm spades are at high risk of being bent and/or broken during insertion.
2. The micro-distribution circuit breakers for the MTS system are unique in that they utilize small, spaded terminals for voltage throughput and, even smaller, spaded terminals for alarm sensory activation. It is imperative that the installer take the time to understand this installation process and potential trouble points before attempting breaker insertion.
