rcbo installation method

All installation methods can be divided into two kinds of protection and selective protection:
All protection mcb circuit breaker the lighting switch boxes, as the master switch, this method is very common, but in the event of failure all circuits are disconnected. Selective protection is to use one of the following air circuit breaker to identify high-risk lines and leakage circuit breaker connection.
Isolated Bus lighting switch box
Total isolation switch power supply through the entire circuit and the power supply by an additional leakage circuit Circuit breaker circuit, direct supply circuits: lights, refrigerators and incubators, through leakage circuit breaker provided include: power socket, bathroom and other circuits.
Ring circuit:
In light switch box can be installed to protect the lower annular leakage circuit breaker provides protection circuit.
