Earthing neutral

Former Community Member over 5 years ago

Why is it forbidden to earth the neutral at the source of a 3 wire system?

Long bare cpc wires inside accessory and junction boxes have a habit of getting pushed against a line conductor or terminal when the box is pushed closed.

Hm! I have to admit that I have wondered about the need for sleeving 'cos the CPC itself isn't going to harm you. With good workmanship, your live conductors should have no copper showing, but I must admit that I have worked with sockets which would (of necessity) take 8 mm² of conductors, but the insulation would not fit into the shrouds.

Then of course, after you have closed it all up, your IR test will show whether any of the conductors have embraced each other.

Who really knows what happens after you screw the cover on tight? Now then, does that fridge light really go off? ?
