Is it a requirement that wiring is to be in steel conduit in a 70mm stud wall.
The wiring will be protected by an MCB and Main RCCB

I assume I can run standard T&E up to where it enters the stud wall, then us a 17th edition junction box to connect to the armoured cable that will run through the wall??
There is a suspended ceiling so I plan to run the cables from the CU on cable trays to above the wall, then drop down in to the wall cavity and run through as needed.
Indeed, I think some of the discussion is probably a bit misleading. AIUI, in a wall with metallic parts, 'bare' T+E is acceptable if it is RCD protected [522.6.203(i)] and, if it is less than 50mm deep (probably inevitable with a 70cm wall, unless plasterboard is very thick), is run in safe zones [522.6.202, referenced from 522.6.203]. Only if those two conditions are not satisfied does one have to 'faff about' with armoured cable, earthed conduit or whatever - at least, as far as satisfying the regs is concerned.Metal studding is used in new houses, I can't imagine that housebashers run armoured cables in new builds?? Or faff about with MF junction boxes etc etc. ... Do you not just run T+E in the appropriate safe zones with RCD protection, and grommets for mechanical protection.
I would have thought so, as far as regs (BS7671) are concerned - but I imagine that, for all sorts of reasons, work in commercial premises needs to be undertaken by qualified electricians.perfect, thank you ... I should have mentioned, does this still apply in commerical? Its just a reception partition wall.
Yes, provided it remains vertically aligned (i.e. within the width of) the socket throughout it's length - although, unless the cable to attached to something, it can be difficult to be sure that is the case!On other thing as well, will vertical run from top of stud wall down to socket level still be within safe zones??
Err....I should have mentioned, does this still apply in commerical? Its just a reception partition wall.
Quite ... which is why I wrote...Err.... Who is doing this work, in a commercial environment, with all that means in terms of EAWR, public and employer liability issues, buildings insurance and lease Ts'n'Cs etc?
... but I imagine that, for all sorts of reasons, work in commercial premises needs to be undertaken by qualified electricians.
I strongly urge you to reconsider.Im going to be carry out the work myself.
