4mm t&e radial circuit

[sjhall]

Hi Lads

Do any of you guys run radial socket circuits ( with multiple points ) in 4mm ? Do you find 2 x 4mm in the back of a socket a squeeze?
Only asking as I've just been passed 2 x 100m drums of 4mm off the lad doing the solar on a job I'm on for doing him a favour.... so 4mm radial... pain in the --- or not so bad ?

Cheers

I do these a lot commercially in white pvc singles. Bit tight in the terminals but doable if cables are dressed/prepped ok. Radials seem to be coming into their own a little bit more now.

I like! Lots of copper there...nice safe radial circuits

I do these a lot, as I mainly do commercial. Some cheaper brands are a squeeze. MK, Schneider etc are absolute fine. Can even get two 6mm into an MK if prepped right

Excellent

Thanks.... worth the 2 hours the favour took.

Would be interesting to know if you can get 2 x 4mm AND 1 x 2.5mm? You just know you're going to need to spur at some point!

Easy! Just put them all into a 5 way Wago, then 1 wire into the socket!

I would install Radials with 4mm2 or 2.5mm2 with 32A or 20A Depending on the situation, or what Appendix 15 BS7671 stated, nothing new with 4mm2 32 A radials, it's all within the Regulations.

Thanks.... it wasn't really a question of can it be done and how... as it's rather basic even for me, it was more of - is it a pain due to size of cable's.

Use the deeper back box

Not really use a deeper back box.

More concerned with 2 x 4mm in a socket.
But as I've had a few good answers, I think there isn't more too add.

Would it really be a spur though if it was a radial or would it just be another socket

No, we use 35mm boxes as standard on all jobs and MK sockets and have no problem. All sockets should take 2 x 4mm cables no problem by design.

I regularly install 4mm2 radial circuits with click mode and Hager sollysta accessories. The Hager stuff is specified to take 3 X 4mm2 conductors.

Appendix 15, figure 15B, page 506 of the BBB calls it that.

But they don’t know sh.. you know what. It isn’t actually a spur in the case of a radial. It’s a branch.
Oh lord forgive me, I’m actually agreeing with “him”

I almost did, but I just can't bring myself to discuss whether it's called a 'branch' or a 'spur'

Go on, it’s Friday night. What else is there to do??
