Hi guys,
It's been 10 years since I was a sparky so I am out of date with current regs. Can anyone tell me the max permitted neutral to earth voltage at a spur. I think it is 1.25v. Please help!

Pme its is required that on a permant install in fault condition nothing greater than 50v n-e

tempory installs and caravan parks/marinas/building sites nothing greater than 25v n-e (obvosioly not pme as this is not permitted on anything that has a safe n-e toch voltage of less than 25v
no volatage should be present on a n-e test if there is u either have bad insulation restance beteween n-e earth /bad wiring or a surge protector that has activated
i hope this helps
