copper conduit possible or not

[J.C.E]

Hi
I am doing a job where the client wants some sockets wired in copper conduit for surfaced mounted sockets on a exposed concrete wall....
has anyone ideas- or steer them towards just using galv!

Copper Spraypaint maybe ?
I have saw some knocked up copper light fittings

and personally don't see any problem with using 22mm copper pipe as containment as long as its adequately earthed.
But I could be wrong perhaps there is some reg lurking somewhere which I'm not aware of prohibiting the use of copper pipe etc.

will just be a few straight stabs of it going from a socket straight into plasterboard ceiling- so can earth the glav conduit through using a coupler and bush and fly leading the back box- but how would this be done if using copper pipe? is there a simular thing to a bush+coupler for copper pipe?

there will be no accessible place to be able to bond in with out it being on show and look crap lol

I don't see an issue with copper pipe either, only problem would be couplers/bushes/fittings.

I believe Marvo has done it.

Personally I would try to steer the customer towards steel conduit, for one thing because as mentioned the fittings are already available and purpose made.
If you're going to paint galvanised conduit you'll most likely need to prime it first otherwise the paint won't stick to the zinc coating.

I would suggest that plumbing pipe used in this manner would not meet the British or harmonised standard for conduit.

solder or compression fitting ?

I don't know if this is any use at all.....not copper but antique brass supposedly. They seem to do 2m packs. Never used it myself but you can check if it's up to standard. Expensive.

Bond it above the ceiling?
Or maybe a conlock bush and jaggy washer?

Dunno though maybe it wouldn’t be such a great idea to use pipe as risteard said it’s not BS or EN standard for conduit....

Unsheathed MICC.

Would there be a thermal consideration to consider?

Water freezes in copper pipes outside. Would PVC twin and skin be ok in copper pipe when winter hits -10 and beyond?
