The leakage protection device in the primary distribution box does not trip
If the circuit breaker does not trip, or the earth-leakage indicator does not change to yellow, check that the circuit breaker is energized. If the circuit breaker is energized correctly, and has not tripped or indicated the earth-leakage fault, replace the MicroLogic4 trip unit. The first reason is that the design configuration is different The design principle of the distribution system is to realize the step-by-step protection from the standard distribution. The leakage protection device works on the basis of leakage current detection, which is an effective safeguard measure for electric power at present. Therefore, it is of great significance to find the leakage position quickly and accurately, and deal with it in time.
