galv conduit in bathroom

Is the point of copper conduit instead of steel simply the appearance as it ages, or is the better conductivity a factor as well?

Marvo, is it actual copper conduit or did you just raid a plumber for some 22mm pipe?

Valid question and you're almost right. Some of it was 22mm plumbing pipe and some in 3/4 hard drawn refrigeration pipe which was close enough to being 20mm and would accept fittings or could be threaded after swaging very slightly. The refrigeration pipe came in 6 m lengths which saves a lot of hassle on longer runs

Not totally sure, but seem to remember the friend working on that project saying that the bronze-alloy conduit boxes were via soldered (or whatever) connections.

Both, but the conductivity, and therefore the lower Zs values obtained, will be out of this world compared with steel conduit!! lol!!

So long as it is continuous you can guaranteed to be meeting the earthing requirements

You can easily achieve that with any steel conduit system, but you won't see the values that a copper system will give you:teeth_smile:

Nothing like stating the bleeding obvious I suppose (You missed off the LOL!!, are you feeling unwell today E54?)

Must keep the rest of the forum on edge thinking we are disagreeing...

After my earthing argument / discussion I have decided to run a length of silver conduit from my house back to the substation for a tasty Ze, and it has the bonus of looking nice and shiny alongside the road. I know people go round nicking copper so I thought that would be a silly material to run in public.
