Link between one light fitting and socket circuit?

[richy3333]

More to the point why were you changing a CU when you should have been in church?

Perhaps it's the vicarage he was working in?

 

[telectrix]

if the church has a graveyard, maybe it's a ghost voltage.:49:

I would isolate, leave the socket circuit disconnected at cu, and do an continuity test from light to said socket circuit to prove, could be doubled up.

 

[uksparks]

Yes the light still works with the sockets fully disconnected at the CU, it's like its just connected for absolutely no reason.

 

[Knobhead]

So you’ve left it like this until next week?

Of course he has, don't you remember this from the last time he found a fault on a CU change. I think it was a cable with a hole drilled through it he found and then left live for a while.

 

[Knobhead]

I though this sounded familiar.

 

[HappyHippyDad]

I must of missed that, where does it say that?

2nd to last paragraph in the OP.

 

[HappyHippyDad]

It's just a matter of doing all your tests now UK, interesting though. Look forward to the update :smile5:

Recall that thread, don't know if it's been fixed yet! But the install is safer now with the RCD's and MCB's so all is good apparently!

 

[uksparks]

Not that old chestnut again, that cable got fixed, see photo below, was very minimal damage to be honest, but still repaired it.

The thing with this is that I nor anyone else would have picked this fault up unless they had the light switch on with a bulb in that lamp holder and did an IR between the sockets snd lights. There's a limit as to how much you can test and that is one that I didn't do.

i won't bite at this but as I couldn't seem to get a voltage reading at the light however much I tried with the light circuit off, I'm not bothered about leaving it until next week. It's been like it probably since the house was built in the 80's anyway.

I was 20 miles from home, and had no means to rip floor boards up, nor was I in the mood to be doing that, especially as its all laminate anyway.

Yes, that old chestnut again because you left a job in a dangerous state rather than fix it.

There’s an echo follows you around, it’s faulty/dangerous, I’ll do it next week.

 

[uksparks]

Did you try it with all of the other lights switched off and just the hall light switched on?

Yes various combinations.

And you fix everything thete and then do you? the installation is no worse than when I found it, if anything it's safer, I'm not entering into am argument about this.

 

[uksparks]

If the circuit feeding the sockets has been disconnected at cu, and the light is still working it can't be linked.

It could be, it worked with it disconnected and connected but only when on same rcd. It's like its wired correctly but with an additional neutral link which is why it works both ways.

 

[uksparks]

But why does the light still work when the socket circuit is diconnected from the CU?

Because it's from what I can te two normal circuits with an additional link on the neutral. I'll find out next week when I go back.

Generally speaking I will fix, or at least diagnose and temporarily fix faults there and then. What I definately don't do is go telling the whole world about any little bodge I may have to do on the spur of the moment. Sometimes I phone my mentor who taught me the trade for a bit of advice or a second opinion.

I agree it is something that I would not have found with any standard testing, it would have showed up pretty quick though once the new cu was fitted as I fit SPSN RCBOs for all circuits as standard.

You shouldn't be ripping floorboards up whatever mood you are in! A tradesman should be carefully lifting them so as to cause the minimum possible damage. Ripping people's houses apart is what demolition contractors and plumbers do.

 

[uksparks]

I accept that, but it's not being left, it's going to be fixed.

you keep your bodged or temp knock ups etc to you and your friends down the pub and I'll continue to post the odd thing on here, I knew I'd get stick for bringing it up.
