Fault on kitchen ring

[TheCodboy]

Hi all. Had a phone call about a tripping RCD. The customer had narrowed it down to the kitchen ring. When I go there,it was indeed the kitchen ring causing the tripping. Firstly checked the usual,nothing plugged in to any of the sockets. Checked the connections at the sockets,these were all fine. Checked end to ends,had continuity on L,N & E. Carried out IR between LN & E at 250v,very low reading,virtually zero. Also tested L-E N-E & L-N. All very low. Now,the cables in the kitchen are red/black and the cables at the board are Brown/Blue. There no sign of any crimps etc at the board (which by the way is a total mess). So I’m thinking hidden joints/jb could be the source of the problem?? Any pointers would be appreciated!

My own professional curiosity (or maybe just my OCD!) would not let me give up before I'd found the reason for the fault.
But that's just me...

Do what you want in your own free time

The customer hasn’t told me of anything else being off but I’ll certainly double check!

Top tip for you - never believe what a customer tells you.

I think you should have spent a little more time on site and found what does what and at least attempted to locate the fault. You could end up rewiring the kitchen ring, only to find out the fault was at a socket in the living room, all along.

That IS tidy compared to many I've seen!

May I suggest a couple of comments here?
Never accept a job without making sure the client knows what your hourly rate is.
Never leave a job undone.

I was asked to solve a lighting problem in a garden, looked at the garden and told the client it would probably take 3 months.
it took about 3 years and found dozens of them....
