Generally speaking, for the light circuit and the five-hole socket circuit, because of the low current, from an economic point of view, 1P circuit breakers are commonly used. If it is for more safety, you can use 1P+N circuit breakers, but personally think it is not necessary, 1P+N circuit breakers a...

Differential coordination means that there should be a certain gap between the upper and lower protective appliances in the network in the setting of the electrical action value. When a short circuit or overcurrent fault occurs at a certain point in the network, whether the protective appliance is a ...
