Help: Wiring up emergency lighting

[liamwalk99]

Trying to wire up emergency lighting, for some reason, this doesn't turn on at all, even when power is isolated it does not come on, so ive added pictures to see if wiring and everything is correct, tested to ensure there was power coming in when CB was on, and that there was none when it was off, any help appreciated, thanks.

 

[davesparks]

It's a greenlee multimeter, CB was on, tested getting 240v roughly, turned CB off, hoping light would be on, no light or battery light, and 0v tested

Why are you using a multimeter? Why not give yourself a chance and use a tester which can rule out phantom voltages?

Why are you working on this light in the first place? Is the battery charged?

Sorry to harp on Liam, just to get my mind straight, you are getting 240v from N to L and 240v from N to SL, as I say sorry to repeat but I wasn't sure from your reply earlier, the reason for asking, is lots of people think they have a link connected only to find the link isn't making contact, ie a bad termination.

it is not a plug and play .

No body said it was Buzz just asking if the connections are good, blimey.

 

[DPG]

I think it's time to try a new light fitting.

sorry pete was not aiming at you .

sorry, 2.5v roughly from N to L and N to SL, 240v from earth to L and earth to SL

You have a dodgy N connection somewhere Liam

brilliant, will try sort it tomorrow morning, change of cable?

 

[DPG]

Test the cable. Don't just replace it. Do R1 R2 and Rn.

Just check the connections, after safe isolation that is.

 

[Rpa07]

Phew I'm exhausted now - can't wait 'til tomorrow. Make sure you come back and update us Liam and SAFETY FIRST.

 

[Pete999]

Test the cable. Don't just replace it. Do R1 R2 and Rn.

What about IR, continuity?

 

[DPG]

R1 and R2 are continuity tests.

 

[Pete999]

R1 and R2 are continuity tests.

[DPG]

Not sure what you're getting at. He needs to verify continuity of supply cable from source to em fitting.

 

[Pete999]

Come on guys he is an apprentice who wants to get his light fitting working, we all know these tests are relevant, lets not take the pess to much, give him a chance to sort it out himself.

 

[DPG]

Surely getting him to test the cable is good advice? It seems like a suspect neutral and there may be a break or a bad jb in the supply cable.
Why do you think these tests are not a good idea?

I don't think they are not a good idea, of course they are, he has been fooking with this problem for long enough, get it working , then test the installation, it's what you would do, isn't it? and don't give any male bovine carp.

How's he going to get it working if he can't find where the neutral fault is? (Assuming it is a neutral fault of course). If we can guide him through some sensible tests it will help his future fault-finding methods.

It's more than likely a bad connection at either the CU, or the light fitting.

It may well be.

Two things:The battery shows a date of 2011 so six years old, maybe defunct. The other is you have no neutral at all. Where the hell is it. The brown and black are the perm. L and Sw/L you are missing the neutral. There should be brown and blue not brown and black for L and N as they are the harmonised colours so something is wrong there. Should be a three core brown/blue/black I guess maybe probably?

How will an IR test help find the fault?

Liam, as an Apprentice do you have an MFT to carry out the tests mentioned in the posts earlier? it looks from your previous answer's that you don't, apologies if I am mistaken, to be politically correct perhaps I should say, if you don't and as you admit you are an Apprentice, why are you messing with something you shouldn't be? this may sound a bit hurtful, it's not meant to be, the other posters are correct, these tests are relevant, but you have asked the question, and you seem to have enough sense to realise what you are doing, sort the problem out, do the safe isolation procedure and the carry out the tests prescribed, I'm out.

Eh? There's a red and black FP type cable in the picture.

 

[davesparks]

?

DPG suggested not randomly replacing the cable but instead to carry out tests to find the fault.

You then suggested an IR test is needed.

So how does an IR test help find this fault?

 

[The Ghost]

Eh?

Well I don't quite know what picture you are looking at but on my screen I see a brown/black the black going to the neutral which I think should be going to L and the brown to S/L then a blue should be going to N. I dont see fp terminated in there with the metal clip
