2 gang socket wiring.

[Mazak]

Maybe obvious, but are any regulations how to fit earth cables?
They always say all must be terminated to back box.
So when 2 cables coming to the box 3 wires sleaved with green/yellow should be inside.
1 of them ending in back box?
Right?
I hope you understand me.
I will make picture later.

Does my box in when people use earth with sheathing or bloody tape wrapped around for fly lead, use singles, personal preference

 

[Engineer54]

Agree.... We use flexible singles in this instance. In fact there are very few solid core conductors throughout the site.

Just about the only time I tend to use the earth lug on a normal metal pattress is when it's a switch. Metal Clads I always join the mounting box with a flying lead, more because of habit than anything else.

But, I've often wondered about how better earthing on a back box may/not affect the Zs in some small way, particularly in many of the older damper properties around here. To my way of thinking, you end up with a 'web' of conductivity via the structure and all those parallel paths add up to something. Maybe. Just curiosity more than anything else!

Thanks for that (especially to who write in proper English, as I don't undestand sloppy sentences).

I believe it might be small difference between that 2 options you are talking about in resistance.
1rst - when earth cables going directly to socket and flying wire going to back box.
2nd - when earth cables going directly to back box and flying wire is going to the socket.
In my opinion is much better to do it as 1rst.

You may want to look at your own English and spelling!! lol!!

Another option is to take one leg to the back box, the other leg to the socket front, and a fly lead linking the two.
This may be a preferred option when space is tight, such as when larger conductors are used, or when there are spurs from the socket being installed.

Posters whose first language is not English making a few mistakes is completely different than English speakers writing gibberish which is all too common on here.

:49:That was embarrassing.

years ago used I used copy an electrician I was with whereby when 2nd fixing a socket I would strip both cables. One leg would go to the earth term in metal box (continuous) but not cut then back out to socket to connect up with 2nd leg earth. I dropped that idea after a while and took both legs to socket, then flt lead back to box. In fact doing installation now, where i have already earthed the back boxes @ first fix stage using some insulated g/y conduit cable.

Well he must have been referring to posts #1 to #11, and to be honest they don't seem particularly bad to me as regards sentence structure. Daz

i terminate both incoming cpc into earth terminal in metal back box and run 2.5 green/yellow conduit wire into the socket. keeps it tidy in there.

I wouldn't do that, The individual CPCs should go into each of the TWO earth terminals in the socket outlet, then a fly lead to the back box from one of them, I believe this is in case a CPC becomes disconnected or breaks at the socket outlet a continuity test will detect this, whereas, by twisting the two CPCs from the cables together and putting them in one earth terminal, it would not show up if the CPCs had become detached from the socket terminal

i would suggest you do it the other way round.

Agree 100% what you say.....but many sockets have only 1 earth terminal. Are not the 2 earth terminal sockets for use with IT equipment / circuits. Nice drawing in OSG

i havent come across any double sockets that only have 1 only single sockets.

we use schneider,crabtree,click,legrand etc

 

[Guest77]

Very cheap double sockets have one earth terminal, very cheap ones, 90 pence from CEF lol, most double sockets which are over a quid have 2 pmsl.
