Both neutral and phase wires are connected through an RCCB. The combination of these two devices provides a very effective form of protection from electric shock, and it is widely used for protection against a leakage current of about 30,100 and 200mA.
WebThe RCCB has very similar functionality to the RCBO. However, it doesn’t provide integral overcurrent protection and so doesn’t safeguard against overloading or short-circuiting. Rather, the RCCB provides exclusive earth leakage protection and requires the fitting of an external CB for the assurance of overload and short circuit protection.
