Steel conduits acceptable for earthing in domestic property ?

[ipf]

I test at each point and check condition of the backbox - which in one case revealed severe corrosion problems. It’s this arrangement that reminds us the purpose of the earthing lug in the backbox was to provide the earth to the socket - not like we do today with T&E and bond to it.

We're earthing the backbox not bonding it.

Correct. My mistake, well spotted. I think I was getting to direction and went off at a tangent. With conduit we take the earth from the backbox with T&E we take an earth to it.

Rewiring through the old conduits could be a problem.
Last one I worked on had a central box with pipes running out to all the sockets.
This box was just under the floorboards, and no access hatch. Had to cut one.

Give the customer the idea that decorating now would be wrong. Go for a rewire first. There won’t be enough sockets for them even changing all the singles to doubles.
