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

o

is it not time you should be in bed reading a comic .

Come on buzz, the lad's a bit puzzled......it'll do him no good going to bed with a copy of the 18th edition....

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

That’s what I was thinking, thanks a lot

True, and is the light switched on or off...is it a permanent live or switched? A few unknowns. Is there only one cable at the fitting? If so, odds are there's a nearby joint, of some kind.

A bit of late night viewing on loop impedance testing

 

[Darrens14]

Switched I have taken the fittings down and have cables In connectors the way they were connected in light so nothing has changed (connection wise)

Try and test near the consumer on the lighting circuit and see what voltage between the line and cpc

….is their a bunch of cables above the ceiling?...may be something amiss there. If it's a switch wire, that's the first thing to look at.

I will have a look tomorrow I have a feeling that could Be it.. it’s a single poll switch but whoever done it has blue in common brown in l1 earth in l2 so I’m thinking is the earth mixed in a junction box because it’s t&e at switch and pvc pvc singles in ceiling

Isolate first!!!!!!!!!! then you can check continuities.
Get some lever wagos for temp connections, then no mix ups.

 

[Darrens14]

OF course

That's looking more serious...…..earth in L2? Be Careful and get some advice if you've any doubts.

I’m gonna hand the job to a family friend (qualified) thanks anyways for your advice and help

I am currently redoing a kitchen, (electrics) I tested voltage at lighting cable and form brown>blue-230ac
Brown>earth I got 25ac could anyone shed some light on this please

What’s the Ze? And the Zs?

Give him a lift with it....if he knows his stuff, you'll learn.

 

[Darrens14]

Appreciate the humble replies. Thanks a lotto

Clearly your earth is not bonded and could even be open circuit.

If your wondering why many responses are snarky ?
This is basic stuff and if you are working on electrical you should know and understand at least the basics.

that sets alarm bells ringing. looks like the cpc has been used as a live conductor in a 2 way set up.

Hi - As Marvo has said it's likely cpc not continuous. Do you have a loop tester?

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

if it is wired correctly, which i doubt, he should have 230V L-E.
