[QUOTE="sellers, post: 172605, member: 2357"] Just to get my head around this, at 230v 30mA, means a 7666ohm short or less will trip the rcd. now the test load say it be 7000ohm would trip with no loads connected. Then connect a N+E fault on a tncs system. With the n + e paths being of the same resistance the test fault would be taken down both conductors roughly equaly thus halving the fault current, not tripping the rcd? [/QUOTE]
