Tripping mcb - lighting circuit

[shanky887614]

Drum of singles and continuity tester is what I would use to check for loose connection.

First thing though is there one or more cables at each fitting?

If there is only one then there is a probably a jb somewhere

Cheers shanky, only 1 cable at each fitting mate which suggest to me a JB between fittings as you say

Ive taken on board what you have all said and will give it another go in the morning, I WILL fix the problem lol !

Only thing bothering me was the one time I turned the switch on and the lights were dim, with a crackling coming from C.U which to me I would have said loose connection but I checked and the cables were tight

Steve, yes mate, ive given her a a few lamps just for at night, shes plenty of light in there

Cheers guys, this is what the trainee section is all about !

Good stuff, mate. You'll sort it

 

[Simonslimline]

Just to be sure you have checked that all the connections are tight in the cu and not just the circuit you are faultfinding on?

As you have said crackling could indicate a loose or poor electrical connection.

My dad had a spark put in a board for an outside music studio in and the idiot didnt tighten the breaker on to the bus bar , anyway the busbur turned black and the cu nearly caught fire.

Seriously visually look to see the breakers are sat on the busbar correctly and as tel said not placed on it but behind the mcb terminal.

I did check mate, but I will definitely check again in the morning, ill go and grab a new mcb to try aswell so will make sure everything is fitted and terminated correctly when I go back

Cheers Simon and everyone else, great advice in this section as always !

Pretty much as tel says really, if you have access to the loft you could look for jbs with loose terminations and any obvious signs of damage if you dont know how to use a MFT. Obviously isolating first and proving dead with your voltage tester!
But i admire your opening post and honesty to say that your a trainee and have no idea how to use a MFT. Some of the keyboard gangsters on here will say you should not be doing anything without supervision blah blah blah but you said yourself if its out of your depth then you will leave it to a competent sparks.
This is how you learn and it has got your brain thinking and hope you find the fault mate !!

If you had lights coming on dimly and there was a crackling at the CU then it's very highly likely there's a poor connection in the CU somewhere.

Good post, with honesty, and good brain rattling.....Paul will be proud

Alright Matt, lets get the old lass sorted out. I'll pop over on Friday with everything you need to get the perfect end result for her. Well it is Good Friday so lets do something good lol. And yes it is free of charge.

This is a good little fault finding exercise for you, seems like you are looking in the correct direction already with the help from all the other trainee's (which I am very impressed with BTW, well done, I love it).

Sort a time out with your "customer" for Friday, (about 9:30 - 11:00 suits me. Well it is a bit of a drive..... kind of) Matt you have my number so give me a call/text or PM and we will go round and fix it. Simple has that really. I'll show you my way of step by step fault finding, same as what has been posted up already but no-one has mention a "spider JB" yet? I think it is a bit more than that but it will be working by the time we leave the house Matt, that I am sure off

And within the same hour as that post, I have been made a Moderator!!!!! Well, it's not quite Pope but it will do for now pmsl.

Whoops, am I allowed to say things like pmsl etc??? I'll have to go to the Mods section and look at the new rules that I am now under :rofl:

Did you fettle it?

Did you fettle it?

No, Matt did not get back to me. We text each other and he was going to arrange a time with the old lady but I have not heard anything since? I'll call him later today.
