Adding 5A lighting sockets.

[Digi77]

Need to add some 5A lighting sockets to a lounge, easy option would be to sit them next to the existing 2G 13A sockets in wall these are feed buy a 2.5mm ring down 20-22mm oval conduit in block wall. There's just enough space to squeeze a 1.5mm T&E down the conduit then loop thro the 2G box and cut in a new 1G box next to it alot less mess and effort than chasing.

Is there anything wrong with doing the above cable route mixing ring/lights thro a wall box, and adding the extra cable to the conduit because it will be a tight fit will there be any cable heat issues.

Not only heat issues, you shouldn't pass a new circuit through an enclosure of an existing circuit ie the 1.5 passing through the 2 gang socket box

 

[Digi77]

Ok thanks

Why not? It's very common in conduit installations.

this is the first time i ever heard anyone claim you should not install a new cable in an existing conduit!! It is nonsense and definitely not true,if there is space you can put another cable in there and that's why conduit and trunking comes in various sizes so you can fit more cables in a length instead of having loads of individual cable runs

Pete is suggesting it is bad practise to run a lighting cable through the actual socket not so much the conduit, I see his point, it is a case of some of us older sparks were trained it was bad practise rather than it is a problem, he is experienced and passing on his opinion, the fact is if I was in the same position as the OP I would do it, but I wouldn't feel happy having a different circuit passing through a socket box, like I said training rather than any real problem lol.

Not running through the accessories it aint, or should'nt

Thats why T boxes were invented pete so the sockets can sit on the top spout and the cables run through the box underneath lol, these kids today chuckle.

I agree mate but this chap is on about running through he 13Amp socket box, kids of today

Yeah thats right, hopefully he will understand your view now fella.

I wonder.

Never 2 different circuits through 1 box

 

[telectrix]

if OP does not want the lights switched by a wall mounted light switch, why not just spur off the socket?

It shouldn't be as far as I know.
I was taught never to run cables of one circuit through any accessory backbox on another circuit
For example a lightswitch with a twin socket directly below it in conduit should have either seperate drops or a tee box to connect the switch and the conduit carries on to the socket.
But I can't back this up in regulations, it's just something which I was taught as 'the way it is done' as an apprentice

 

[Risteard]

Exactly, because it doesn't contravene any. In fact many books completely dispel the myth of "bad practice".

What about conduits running into an adaptable box, or an adaptable box bushed off a trunking?

Or a dis board, which will obviously have many circuits within it.

There is absolutely no reason for multiple circuits not to be contained within them.
