[QUOTE="Steve3948, post: 381655, member: 2497"] John, I'm not sure I follow your science, if you have no voltage at the RCD then the circuit is dead, so where's the issue, it obviously needs a mains from the supply to operate or it's not required because with no voltage nothings on. On your 1277A fault current you have your OCPD so that would trip within 0.4 sec. On leakage to earth the RCD would trip within required time. [/QUOTE]
