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 !

Went to do an EICR a couple of weeks ago and found the whole extention and indoor pool/spa area wired like this.


She said the builder that wired it said he was also an electrician..... and he didn't need to give a EIC as it was only an extention not a new build.

 

[trev]

He probably didn't need to test it either since it was an extension, or maybe he just knew it was ok. Bloody shyster

 

[micksparky]

yes maybe he had a kind of e.s.p that rendered the need for testing unnecessary.

 

[trev]

I've worked with guys who have had that Mike. I wasn't blessed with it so I still prefer to spend the time with my test gear

What's the problem! The socket will be earthed via the screws and back box.......I don't think so.

 

[ayjay]

i worked /did my apprentiship for meggitt marsh, we used to install ringmains in steel conduit with no cpc
the earthing was reliant on the socket fixing screws only
if the earthing was crap we just went around tightening the 20mm bushes in the ko boxes!

 

[electrifix]

fitted a curtain pole at my own house...knew the fixing would be close to cable but decided... eeahh be reet! all was ok till my wife and i put the weight of the curtains on the pole... stood admiring them then my wife closed them and sparks flew from the metal pole and rings whooops!! ...if only we'd bought foil curtains!!! lol!!

Why did you not just tag from the back box to the socket faceplate??
You would still need to tag it despite it being 'effectively' earthed through the screws.....

As long as there's a fixed lug you don't have to Rich. I was taught to take the cables to the terminal on the socket then a lead to the box and still do it to this day, for the amount of time it takes I deem it worthwhile but it's not a necessity.
Dog rough if you don't imho

 

[rich.250]

I know you can rely on it the other way round to earth a metal box but don't agree that you should have no cables in the earth terminals in a socket. As it wouldn't be installed to manufacturers instructions would it.....??
And I agree trev! Rough!
I thought if it had a terminal it should be connected to it? Will have a look for the reg I'm thinking of later

When I am wiring a socket on a ring final I WILL always sleeve the cpcs separately, I will connect the two from the cables (ring) into the terminal on the metal box. Then I will always have one cpc from that terminal to the earth terminal on the socket and when one wire is being terminated, I always double the end over.

 

[Ohmyword]

I agree with Trev. I've been 'in the trade' all my working life (& I'm 60 now). I always take the cpc's to the socket terminals first & loop out to the metal box. Over the years the earthing/bonding of the metal boxes was relaxed. In my opinion, if one does it the other way round and a good connection is not made on metal box terminal, the earthing to the socket could 'fail'. I reckon that it's better to lose the earthing of the box than the earthing of the socket
If there are two earthing terminals on the socket would you use each one ie. connect the cpc of one ring cable to one terminal & the other cpc to the other?
I still think connecting both cpc's in the one terminal makes more sense. I use the same reasoning (as earthing box) because if one bad connection is somehow made (or wire broken) then continuity of ring cpc could be compromised.

 

[trev]

I always put both cable CPCs in one terminal on the socket with a loop out to the box.

 

[Swicade]

I'll admit i tend not to loop to the back of the box at all...only time i do is if it's a metal clad surface backbox...since they relaxed the backbox earthing. CPC's are always seperatelyt sheathed and then connected to the same earth terminal though.

 

[rich.250]

The same earth terminal is fine IMO. Unless its for high integrity earthing!

Although I always put one in each and then a tag off one.

As for going to the back box first. I'm not keen, as said above. If you have a lost connection the socket could be used with no CPC.......

A kitchen that has had under cabinet lighting fitted by a local electrical company.
The only bit I opened was the lid to the J201, so they used a J201 for the neutral and wagos not in an enclosure for the rest... WTF?

 

[ayjay]

12 volts?- still ,i can,t understand why the installer did that--
probably a boy left alone, non supervised, or a clueless idiot

I was thinking more on the lines of - monkey :-D

no no - this is the 230 supply to the downlighters!

Each to their own but I see that as incredibly bad practice.
