Is it ok to use a single pole rcbo to protect the garage supply cable as a rcbo is a combined rcd and mcb, i was concerned that i thought both the phase and neutral conductors had to be switched off in the event of a fault or overload.
The Local electricity board replaced my dads 32a breaker (for the downstairs sockets) with an rcd now i thought a rcd only gave fault protection but not overload protection so have they made a mistake as the 32a mcb has now been removed.
