The ability of a breaker to trip when something is wrong is the most crucial requirement, whether the issue is a shorted electrical line, a stuck motor, or someone inadvertently contacting an electrified component. 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. 6 What do you need to know before replacing circuit breakers?
