No earth on ring main.

Hi guys I am re-wiring a bathroom. I have done first fix for fan, down-lights and switches on the lighting circuit. I had to pick an earth up from some old conduit and will of course test this for continuity. Now when I have taken a front plate off of a single socket I have found there to be no earth conductors on the ring cables although there is one in a cable which spurs off of it. It's hard to see if the cables are running in conduit or not which may be acting as an earth if it is. Was this common practise years back, to use conduit as the means of earthing? What do I advise the customer? Does the house require a re-wire? I will try and run my spurs from elsewhere though I think. Any advise welcome. Ta.

Nothing wrong with metal conduit as a means of earthing as long as its continuous . Did you test for a earth at the socket?

 

[monkster]

test for zs would have been a good start

Believe it or not years ago they even used trunking and SWA as an earth lol

No I haven't done any testing as yet as I spent the day sorting the down-lights and running new cables etc... discovered the socket situation at the end of the day. I replaced it with a class 2 socket as it was a metal front plate just to be on the safe side. Will do R1 & R2 test for continuity when I return. If there is no earth though what's the correct advise and action to follow? Thanks for your replies.

What's this class 2 socket just to be on the safe side statement????

 

[Clark3169]

A plastic front plate. One that wont become live if a line conductor pops out as it did before. It's a temp measure until I can test and get it sorted tomorrow.

Just cut the green&yellow stuff out never did like the colours lol:32:

 

[Clark3169]

Ha ha yeah two conductors are quicker to install than three. Your right ill do away with them altogether ha ha.

KAS1 what's the concern you've got me worried now? Am I missing something? (Other than the plot)

 

[KAS1]

An earth by the sounds of it.

So what happens when someone plugs into your class 2 socket ???

A zs would have been quicker than Changing the socket

Been like it donkeys years and yet needs a 'temporary' for 24 hrs?...BTW there's no such thing as a class2 socket,they all need earthing.

 

[monkster]

class two quality put a sticker on socket with the words ONLY double insulated allowed pmsl

Hmmm class 2 sockets, I think I can feel a Dragon's Den thing coming on. Reckon I'll get very far guys?
I don't
