The ones made by Klein are often reliable and considerably more convenient because of their built-in features. 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. Low-voltage Circuit Breakers should be inspected and maintained every 1 to 3 years, depending on their service and operating conditions.

This allows you to work on a circuit without being exposed to dangerous voltage. Since the breakers in question are 120 volt branch circuit breakers, the easiest way to test them would be to remove the panel cover, disconnect (and isolate) one of the trip coil wires, disconnect the load wire, and try to re-set the breaker. An electrostatic wand or volt stick can indicate if a wire is hot without being in direct contact with it. 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. While some circuit breakers can last longer, arc fault (AFCI) and ground fault (GFCI) type breakers have a shorter 10- to 15-year life because the internal sensors wear out quicker than the breaker.
