Breakers that are not working correctly can result in the personal protective equipment selected using the tables in NFPA 70E being inadequate. Breaker failures can also invalidate arc-flash studies due to clearing times becoming an unknown element. A tripped breaker can fail to open all contacts, fail to latch, fail to quench an arc, or fault to ground. While the failures modes vary, they all have one thing in common: they can be avoided with routine maintenance checks. An industrial breaker can trip for a variety of reasons. In addition to tripping on overcurrent and ground faults, breakers can trip on loss of voltage as well as on sensing an arc flash. Breakers may also have fault detection settings that coordinate with upstream protective devices in order to isolate the fault with minimum interruption to the remaining electrical system. 18 AWG Current Rating, How to Install a 240V Circuit Breaker?

ANSI Standards Section 9.5.1 recommends all circuit breakers be tested and excercised on a once a year basis. The residual current device (RCD) or residual current circuit breaker (RCCB) enables the rapid disconnection of electricity, thereby avoiding prolonged and potentially serious shocks. This breaker coordination is based on either current discrimination between upstream and downstream devices, or time discrimination between upstream and downstream devices. Time discrimination is based on the response clearing time of each breaker, so that downstream breakers trip before upstream breakers. When they do, a breaker can perform its intended function without the rest of the system going down. When they dont, then an upstream breaker can unnecessarily take the whole system down, which may pose its own safety consequences. How often should I maintenance my Circuit Breaker? If too much electricity is going through an outlet, the circuit breaker will trip to prevent overheating. Either they have tripped, in which case you curse the darkness as you descend into the basement to reset them.
