We're doing a PIR today at some offices , about to read r1 + r2 on a radial to a hand drier, my mate ,at the board , flicks the breaker off marked hand drier and shoves our jumper wire from the earth bar in the terminal.
BANG
Oh joy of joys , its not the radial to the hand drier but a leg of a ring main, the other leg being in another mcb and live .
Well, you know what we always say , you gotta test everything or one day its gonna bite back. :_|
