Metal sockets and conduits allowed?


Recommended Posts

Looking for some advice please. I’m planning to rewire my French holiday home and really wanted to replace the plastic sockets and exposed trunking with metal for aesthetic reasons.  From what I have read it sounds like this may not be allowed? The property is just about to be earthed as wasn’t when we bought it - copper rod into ground. 
 

if anyone can advise would be hugely appreciated.

 

thanks

Having had experience of steel conduit wiring when I was an apprentice doing six months with the factory electricians in the UK many years ago, I wouldn't use it if plastic conduit is an alternative.

Without going into the finer details, you will have to cut to length and thread every piece of conduit to screw into the bushes which you fit into the socket boxes. That means that every threaded end will be covered in cutting paste - like a grease- from the threading which will have to be cleaned off.

and a pipe vise to hold the pipe while you are threading it.

And turning the threading die is really hard work.

You have to ensure that all burrs and  internal sharp edges are removed so that when the wiring is pulled through the insulation doesn't get damaged on any sharp edges.

I guess you are getting the picture now - don't use steel conduit in a domestic installation.

Ah! Those were the days! Don't forget the pipe former (can't remember its name!) for  bending the pipework around corners and adjusting levels. Yep, use plastic, it's a doddle!
