Abstract
An apparatus and a method are provided to reduce arcing between a circuit breaker having a breaker line terminal and a panel board terminal of an electrical panel board during installation and/or removal. The apparatus has an auto tripping mechanism including an auto trip lever having an end and a spring disposed at or near the end of the auto trip lever. The auto trip lever is configured to interface with an armature in a module one that houses a cradle of a breaker mechanism. The breaker mechanism is prevented from latching until the circuit breaker has been installed in the electrical panel board by keeping a breaker handle in a tripped position when the breaker line terminal and the panel board terminal are connected. The spring is configured to force the auto trip lever to rotate for providing a force and a deflection to automatically trip the circuit breaker as the circuit breaker is being removed from the electrical panel board and before the breaker line terminal and the panel board terminal separate.
