[QUOTE="SidTheSparky, post: 194119, member: 3132"] Both lights on one MCB. Good point. I'll correct that. Thanks. As for trip times - they ought to be <40ms @x1. Only the lights seem to be managing this. What puzzles me more is that they have a higher impedance than the socket circuits so they should take longer to trip. I've always taken it for granted that trip times would be higher for higher impedances. My recorded readings are somehow quirky. [/QUOTE]
