Trunking/conduit?

[ABCwarrior]

After a lengthy debate on here last November as to the pitfalls in installing a new CU and shower, I've decided to get it done by a sparky now that I've got the shower and sussed the plumbing...
My neighbour has had the same thing done but his sparky used that really ugly boxy conduit to put the cable to the shower in, way oversized to the cable.Butt ugly....

Can anyone recommend a brand/site that actually does aesthetically pleasing stuff? Closest I've seen is the circular stuff in Screwfix but the 90degree corners are a bit OTT. They do some neat oval stuff(the profile looks like it would fit 10mm T+E nicely) in 2m lengths but unless there's something I don't know they don't sell internal/external corners for it? Is it bendable or something?

Cheers.

Out of interest, why are you running it in conduit?

 

[ABCwarrior]

Because it will be surface mounted for a few metres? Thought it had to be if exposed? Either that or tacked on with clips which would look worse...

MICC's very neat if it's done properly.

The oval channel is designed for use in plaster and ist't actually conduit as such.

Round plastic conduit can be bent with a bending spring and hot air gun if you don't like the manufacturered corners.

A friend of mine had a 7KW shower installed about 10 years ago and is working on a 32 amp mcb on a obsolete crabtree CU.

What an eyesore but now it's were it should have been put in the first place in the main trunking that carries the rest of the cables.

I've got a 15mm plumbers spring, would that do? I note it all seems to come in 16mm or 20mm diameter, which would be best for 10mm T+E?(got a bit in the shed but it's blawin a gale out there at the moment!)

You're going to need 25mm conduit for 10.0mm² T&E, and even then it'll be a struggle for anything other than a straight run.

You need a 25mm bending spring for 25mm conduit.

I would forget using conduit and use trunking instead.
D-line is a little more aesthetically pleasing to the eye. Do also be aware that installing cable in trunking or conduit will lead to the cable rating being reduced.

Top advice folks, much appreciated. The cable run will be at a maximum 7m, pass through one stud partition wall(no insulation inside, it's the frame for some sliding door cupboards) and up through the ceiling/floor of the bathroom above and down back through it in the corner to the shower. Floors are 250mm with insulation. Depending on which way around the utility room it's routed it will either be 1.5m inside the conduit/trunking or 3.5m...
Does cable inside a cupboard at ceiling level need trunking/conduit too or can that just be clipped to the wall/ceiling interface?

Found a sparky that will work for £20 an hour cash in hand, but does this mean he won't be able to sign off the work because it would leave a "paper trail"?(Remember I'm in Scotland, NO part P)
So to keep the costs as low as possible I'm sorting all this out before he starts(routing, trunking/conduit, hole drilling etc)
Incidentally what does signing off etc mean? Do we get some sort of paperwork to keep with the house documents etc to pass on should we move?

Not now you wont.

If you're using T/E cable, clipping to wall/ceiling, anywhere, is acceptable, provided there is not any particular risk of mechanical damage (rare in a residential property). If surface trunking/conduit is used, it's only for appearance.

Kind Regards, John.

sh*te...back to the drawing board. Not paying someone £20 an hour for something which at the end would be the equivalent of me doing it...!

Got a full set of testers, or an MFT, have you, and you know how to use them?

 

[ABCwarrior]

I'm not doing it myself BAS, anyway word on the street is you aint no sparky just handy at reading manuals and regurgitating the contents on here...

I'm not doing it myself BAS,

So what did this mean?

Not paying someone £20 an hour for something which at the end would be the equivalent of me doing it...!

Who is doing it?

Someone charging even less than £20ph?

Has he got the ability to test his work?

Unless you have then paying an electrician is not the equivalent of you doing it.

anyway word on the street is you aint no sparky

Can you show how that means I shouldn't have asked what I did?
