Installing two double sockets in loft..

[borderfox100]

I want to install two double sockets in the loft - one on each gable wall. Its a new build and the sparks ran all the electrical cabling over the surface/joists.

Can I do the following;

Find a cable thats leading to a double socket in one of the bedrooms - then install a junction box and spur off it?

Is there any guide online that covers this?

Hello,

If you can find a ring and confirm it is a ring then it is ok for you to do so. about connections...

You can either split the ring if the cables are long enough to reach to your sockets and then put a link in between your 2 new double sockets to maintain the ring. or,

if you use a junction box, do not cut the cable and try and strip it back with a stanley knife and run it through a junction box and add your cable for the spur.

hope this helps,

How do you put on your earth sleeving if you don't cut the cable?

Why "do not" cut the cable anyway?

What would be the implications of taping into a spur and not the ring itself? Is it just the potential for it being overloaded?

yeah, that and your house burning down when the overloaded cable sets on fire.

Ok, thats a good reason.

When you say "tap into a spur". What do you mean? a spur existing from the ring final circuit?

If you were to source your power from a spur off the existing ring final circuit then you would have to have fuse protection rated at 13amp for sockets. ie. switch fuse spur.

I want to know why you should not cut the cables when using a JB

Only thing i can think of is when there is no slack on the existing cable.

Obviuosly the earth wire has to be cut but the live and neutral wires do not.

Just finished first year 0f 2330.

One tutor said not to cut into the ring in a JB so as to maintain the integrity of the wiring and not sleeve the earth.

T'other one said cut the earth and sleeve it....

Blokes at work said 'Uh! Why not cut the wires?'

Well if there is enough slack to cut the earth, sleeve it, and join it back together, there must be enough slack to cut and join the live and neutral.

The earth MUST be sleeved period. Methinks they mean to terminate the cable in such a way that the grey sheathing butts right up to the terminals so that the live and neutral bend off but the earth goes straight in....either way its not good custom and practice to do it in such a way so.... sleeve the earth.

RF, when you cut the cable to fit a joint box you have to carefully seperate the live and neutal to fit the two outer terminals, by doing this the earth starts to slightly twist, you then cut it and will find that there is just enough slack to fit into the middle terminal.
