As to household systems, all RCDs are set to activate at lower than 100mA which can still provide a nasty tingle up the arm - just ask my builder, he found a loose wire in a wall cavity with his bare knuckle - the wire had been cut off and hanging in space by the previous owner who mustn't have liked the old GPO position.
