Live to earth 25ac live to neutral 230 could anyone help

[Octopus]

What were the R1 + R2 readings like?

Full set of dead tests needed. And draw out the circuit as you find out what goes where.

And as above, safe working practices while you are testing, especially as it sounds like somem of the wiring may be incorrect and may catch you out.

Let us know the outcome - sounds intriguing.

if it's 2 way switching, i bet some muppet has used T/E for strappers and the cpc is used as a live conductor.

Another option, is that the polarity is reversed.
Test a socket, see what readings you get.

You shouldn't be getting 25V between Neutral and Earth either.

Not sure I agree with that .......... try turning off the other circuit breakers as it sounds like induced voltage to me

That was my first thought,but although i'm not a Fluke devotee,i think the T5-600 he is using,is an AVI.

Of course,that does not help,unless we know exactly where the probes are going

This isn't the kinda problem that can be solved over the internet so I'm going to close this thread. There's too many possibilities and a lighting circuit can be legitimately wired in numerous ways which can also cause confusion. There may even be more that one problem as well and the situation at the moment sounds like it's possibly dangerous or at least potentially dangerous.

You're going to have to get some assistance from someone with a full range of test equipment who can do the usual barrage of dead tests and figure out how the circuit is wired. As already mentioned, if you're an apprentice I'm sure you could help the other sparky out and get some experience whilst you're at it.
