[QUOTE="mike spark, post: 16151, member: 1053"] Yeah thats what i was taught that an RCD will still operate on circuit with no CPC but i got myself a little confused during this thread. I understood it that a circuit with no CPC will trip if contact is made with phase or neutral, and that any short between phase and neutral will trip the MCB. Also that if the RCD has tripped and the circuit with no CPC has passed contnuity/IR then that circuit is not tripping the RCD. Would i be right for thinking such terrible thoughts;) :^O ? [/QUOTE]
