galv conduit in bathroom

[benji]

could use it as a towel rail

Nice....they do make stainless steel conduit you know...Muhahahaha (try cutting and threading the stuff though, real ball ache)

ptfe?

why not run a little silicon around the thread first and again when you have finished and it will be water tight then

Same problem as PTFE use, it would risk negating the electrical connection between the conduit sections, however after putting the joints together I would not see there would be an issue with smearing a small drop of clear silicone around the joint. On our commercial installs outside where water can run down the conduit, where the conduit rises vertically or is overly exposed, we do this all joints, have done for years.

Copper conduit and be done with

Wonder how much that would cost?? Much of the Houses of Parliament has copper conduit installations, i know that project came with astronomical costs...

I remember our tutor at college in the 70s told us about the copper conduit at The Houses of parliament many years ago, I've never been and checked it out though lol

I have copper conduit in my house. I went with copper because of the building design it's exposed in quite a few places. Can't remember what it cost but there's only maybe 60-80 meters of it so it wasn't the end of the world.

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

 

[Toonlad]

PTFE:- Plumbers tape for electricians.

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

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.
