Earthing

[DomCallear]

When earthing the steel (running an earth cable from the steel to the earth bar) does the clamp onto the RSJ have to be visible or can it be behind a wall?

Is there any regs to say you can or can't, or is it just good practice to put the earth clamp on an RSJ that's visible? I'm an apprentice and was really just wondering.

The connection is required to be accessible for inspection, testing and maintenance purposes and must be complete with the usual warning notice as in a BS 951 clamp.

Regulation 526.3 if anyone tell you different from IQ

Have seen it where a 12mm stud has been welded to the RSJ and cable bolted to it using a lug with 2 nuts on the back and nylok nut on the front.

Unless the connection is deemed permenant, it must be accessible.
