Silly question from a newbie

sparky in training · Aug 3, 2017

Hi All

I am quite new to electrics and I am still earning but wanted to ask about extending a ring final circuit using crimps. In order to do this am I right in thinking that the new socket would need to have 2.5/1.5 t&e run to the an existing socket. Remove one of the existing wires and crimp to an incoming wire from the new socket. Put the other incoming wire into the terminal where the old wire has been removed. (obviously same process for neutral) I am sorry if I have worded this in a weird way. I will see if I can do a drawing and upload it.) I know the junction box method is an alternative but I saw a socket use crimps once and it looked like a lot was going on at the back box!

Sorry if this is a really basic question

Essentially yes.

Are you just wishing to add a new socket?

I have uploaded a crude drawing, hopefully trying to explain what I mean

Not as a spur no, this was more of a theoretical question than me actually doing it. Just for knowledge really

Yes this is a possible method of managing to extend the ring without just having a spur, there is not a lot of room in a back box to do this but it is possible and may be employed if there is no alternative.
Don't forget the earthing!

Thankyou, es I left the earth out for simplicity. I know what you mean about the spacing in the back box.

easiest connectors to use in limited space are the ideal in-line splice connector (push in).

Agree, use inline push-wire splices or Wagos in preference to crimps, if wired in T+E. Most insulated crimp terminals that you would buy over the counter make a poor connection to solid conductors. There are special types designed for the purpose but you need the dedicated tool and die set. You will see ordinary crimps used, mainly because some 'electricians' seem remarkably unconcerned about making good connections.

Don't forget to make sure the CPC of the through-connection is completely insulated so that it doesn't contact the back box. Although this would not compromise safety, it might show up as a fault during testing.

From what I've read on here, other forums and the web, you could base a whole weekend conference on that very subject

Get yourself a box of wagos and push in wire connectors like telectrix mentioned they come in so handy as they take up little space
