    Sports pavilion rcbos or rccb incommer

    Hello guys. I was asked to quote to replace a 3 phase db in a sports pavilion. All cables are twin and Earth in the wall.

    RCCB as main switch?

    Hi all, I have been to a property where the tails come out of the meter and into an RCCB which then feeds the main switch of the consumer unit. All circuits are protected by MCBs. If I'm adding a new circuit, is it best put in an RCBO instead of an MCB? Thanks

    I'm a Canadian electrician thrown into the 'European' wiring world (not in Europe though). I was just reading up on RCCB in that they are 'similar' to our GFCI's but do not provide over current protection, therefore, an RCBO is required as the O in RCBO is over current protection. As I've been...
