NEUTRAL EARTH FAULT
I would just like to correct my message title for me mucking up :13:
A guy I work with was sent to change a mains board the other week. He isolated the supply and proved it was dead, He started stripping the board out and got a zap! He checking and noticed he got 230v between neutral and earth on the cable insulation ! This is what he had touched.
Has anyone every come across this ? The supply was old, im not sure what kind but I think he said it was a rubber cable. An older spark told us they used to make the insulation with some conductive compound materials incorporated into the insulation years ago ?
