Tell us about your faults!

[kung]

Hi ALL
Just thought id put this one up for all those faults we find.
heres one to kick it off !
Domestic RCD tripped and wouldnt reset cause was a blown low energy light bulb.
There you go now for yours !

I was asked to look at the kitchen wiring of a neighbour partly because the neon light on his new cooker switch stayed on constantly even when the switch was off (supply and load connections reversed) and partly because he didn't trust the guy who did the wiring (something about scratching his head a lot). Found 12 different faults not including multiple instances of some of the faults. A few of the others are:
Reverse polarity at one of the sockets;
Wrong conductor size (1.5mm) used to extend the ring to several sockets on a spur;
No FCU on that spur;
No RCD;
Brown sleeving used to cover cpc - where they bothered;
No CPC continuity;

This was all in one room. No certificate of course. And these guys offered to rewire his house for him too!

This was found in the ceiling void of a shop.

Funny that, had exact problem last week with a slug! some moron had connector blocked inside a piece of trunking outside to extend the circuit, slug was fried over the line and neutral ... it bloody stunk!

Customer could smell fish? i bet!

are the busbars on this right? first two mcbs on the left are on non RCD side.
busbars are touching, continuity tested them to be sure.
My brain is screaming that this is not right, but i wanted to double check.
the 'cut-out' for the MCB fronts in the DB cover has been modified to fit them all. To me it seems the busbars have been modified to fit everything.
is it right? is it wrong?

DIY job, in cupboard under sink. Has an earth fault



DIY. Spot the issue?



whats the earthing arrangement??


No cooker isolation switch, pulled cooker out..NO OUTLET either. Looked in tiny cupboard above cooker space and found this. Roughly a metre of slack cable lay snaked on top of the cupboard so assume tenant moved it here when refurbed kitchen.

all photos from same property...massive remedials list. DIY central

Nice mess, kerrr-ching!

The RCD is fed top and bottom with the line conductor, if the RCD switches off then the circuits will still be supplied with the line.
However the "contact" for those two busbars may not have enough CCC for the load, though with the neutral off the installation should be at 230V everywhere including the earth, so must have missed something

 

[Kate]

thats what gets me, get 0 or 1v from 'RCD busbar' and either 'RCD circuits neutral bar' or earth bar when the RCD is switched off, and main switch is on. so no feed through the busbars.
But continuity test between the two seperate bars was dead short, and i mean dead short 0.00
ill add a photo of the other half of board...give me a sec

this job is an EICR and not sure if or what to comment about busbars

 

[Richard Burns]

What was the voltage between the two line busbars when the RCD is off and the main switch on and all breakers off?
If 0 then busbars are connected, if 230 then they are not.

 

[Kate]

didnt test between both busbars, only did one busbar at a time to E or N
Main switch on and RCD off:
left busbar 230v to E or N
right busbar 0V to E or N

 

[Richard Burns]

Your continuity test was done with both RCD and main switch off?

- - - Updated - - -

Though the bus bars do look like they are in contact

 

[Kate]

yes, my tester has a panic attack if i do continuity on a live source
they look in contact, continuity proves they are.
Yet no voltage?!? thats why im confused

 

[Richard Burns]

Sorry I assume the supply was off, just trying to get to the source of the differing readings, obviously if the RCD was on then you would get 0 ohms continuity.
