    Do 3 phase boards usually have RCD protection in commercial settings?

    Just sat contemplating life and realised i don't think i've ever seen any RCD protection on the boards we maintain/install at work. I've seen 300mA protection on some section boards but don't recall ever clocking a 30mA in a 3 phase board. Am i just not looking properly?

    Main incoming rcd tripping on any circuit

    My main incoming rcd is tripping out as soon as any load on any circuit. Have pulled each circuit out of the board live and neutral in turn but failed to isolate it to any specific circuit, is this likely to be the rcd at fault?
