GFCIs are designed to protect people from hazardous ground faults that can arise from plugging in defective appliances or corded equipment. 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. Prevent electrical fires. A defective device may create a false sense of security to those who do not know that it is non-functional. Professional electricians sometimes replace individual circuit breakers without shutting the main power supply off, but for an amateur doing this work, it is best to shut off the entire power supply, which interrupts the power to the two hot bus bars running down through the service panel. Why test your breakers and invest in electrical preventative maintenance (EPM) program? Or you flip them deliberately as an isolation device, where the breaker disconnects an electrical source from its load.
