Re: Tell us about your faults !

Thought I'd renew the CU and rewire the garage at my
parents bungalow... nice for my assessment....
Then I had a look in the loft...
So off to TLC tomorrow... going to need a lot more cable!

just thought of another one.

went to a property to assist in a kitchen rip out and remove some socket prior to builders taking a wall out.
when i arrived wall is still up, and most of kitchen still fitted, so i make a start
first off, turn the socket circuit mcb off in the 16th ed board, went back in and checked with socket and see, woah its still live, lucky i checked
so i went back outside and turned off the other socket mcb, back in to check, and still live? im confused now.
daughter was in the shower so i couldnt go any further at that point, so assisted in ripping out the kitchen, and found this

ok looks knackered but its being replaced anyway.

daughters out of the shower so i went back out and turned off the rcd for the protected side,(actually it was already off) back in and its still showing live

so back out again, turned everything off, took cover off the board and there it was..............
at some point, someone had rcd nuisance tripping so they had the bright idea of linking out the rcd (not sorting the fault) only the muppet only did the live, and left the neutral, yet it had still worked????
put the links back as it should of been, left power off and went back to doing what i was there for.
started at that knackered socket from earlier, OMFG

there was a neutral earth fault.........................................

suddenly it was all clear, the reason everything worked was because it was running live to earth, back feeding down the cpc of the kitchen ring

but hold on, the shower and cooker were also on the rcd??????

yep 2 ring mains, cooker, and shower were all running down the neutral earth fault in that socket, and had been for about 2 years. amazingly the cpc survived intact, and ring tested ok

2 very important questions to be raised here.

was the daughter hot, and did you sneek a peek?!

"Do you fix washing machines?"
"Yes, but it's not my preferred type of job", I said. "What's up?"
"It trips the electric every time you put it on."

They'd had a spark round, who said it was the washer, not a fault with the installation.
So I went, checked out the machine. No obvious fault.
Plugged in, switched the SFCU on above the worktop... trip.

Switched off SFCU, meggered back... flat.
Turned out the socket had moisture and dirt ingress.
Replaced the socket, cured the little leak, meggered >299

Power on, Zs 0.71, RCD tests OK.
Take a closer look at the consumer unit and WHAT THE ???????

what? what? what? is it the 50's?

 

[WDMDL]

Well cooker and shower you could go as far as saying that's ok as they're fixed appliances, therefore fixed loads so can't be overloaded as such.

But an RFC... asking for trouble!

Makes me think the board came second hand from one of those "converted premises" the police love raiding?

Wonder if the stairlift guy noticed that in 2008?

if one of the Cpc's is long enough I tend to use one to the box terminal, doubled over not cut and continue it to the socket and join it with the other Cpc so I have two at the socket. If not both to the socket with a link to the box. If that makes any sense.......

Yes, this is exact;y what I was taught to do back in the days of 15th ed and it's what I always did whilst I was full time spark and it's what I still teach my trainee IT technicians that they should do if ever replacing a faceplate of any kind and find it not so already.
Few years ago I replaced all sockets in my parents' garage with new metalclad MK's (they had been 1950's surface mount bakelite MK's). Did this on all of them. 18 months back persuaded mum to get whole house rewired by good spark I know (I'm not reg'd any more) and he asked who had done garage sockets saying he did it that way but had never met anyone else who did until then.
My thinking is if the CPC isn't cut then it's got to be a higher integrity continuity as well as less likely to 'slip out'.
