I have a rather strange domestic layout whereby I will have to route at least 10 metres externally from CU to shower. I am trying to avoid using swa if I can but........ Any suggestions?

PVC conduit?

Dave.

Plastic conduit would get my vote also. 10mm t and e should fit 25mm from memory.

I think SWA would look better long term, conduit tends to fade or discolour in quite a short period of time.

You could terminate the swa externally in an end box if you are struggling for space inside and just extend the internal cores on through without cutting them.( no joint)

Got to be conduit if you dont want to use SWA , and Singles,. T&E will be no fun to try an pull through if you have a bend in the run!
Or galv trunking would be another option

Unless it's a fairly straight run, I'd bite the bullet and use SWA.
You could fit a couple of terminal boxes each end at the point of entry to the house and continue inside from the CU and to the shower with T&E.

I agree with Mike, 10mm is a pain at the best of times, let alone getting it round conduit, why haven't they devised some sort of 'tri rated' cable type PVC that eases the grief in pull cords and the like?.

I'd imagined the run to be straight out and straight up, as I've done before. Anything different to this, I'd take the SWA option. Definitely less sweary.

Unfortunately there are a couple of bends so I don't think conduit is an option. Does anybody make 3 core 10mm suitable for exterior or am I just going to have to bite the bullet.

..... how about pyro, installation is a test but once it weathers the bare copper is often lost against brickwork.

Could get some 10mm 3c nyy-j, might be a bit dear though.

What would be wrong with conduit and 10mm singles?
