[QUOTE="Evans Electric, post: 392799, member: 1408"] Dragging us back to the OP ......if I understand what Mr Benn is saying , as far as I know , to wire in your control / safety circuit you can tap off a 100A phase in your contactor with , say , a short bit of 4mm to feed a control fuse or MCB which in turn , protects your 1.5mm global stop button wiring . This was always in the regs from the 13th as I remember, much the same as smaller CSA cable within, say, a 500A busbar chamber ...short 16mm tails would feed a 60A Sw/fuse . The likelyhood of them ever being damaged or short circuited inside there is minute. [/QUOTE]
