Metal capping outside the 150

[p11jor]

Hi all just thinking when doing a rewire and running the cables down into the meter cupboard then these are never within the 150mm from edge, tomorow I am going to put metal capping over these, how do I connect a earth to this steel? Should I just run a 4mm from the earth block below?

if all cables are directly above the CU, then no problem.

I am talking them being plastered over?

Same rules apply mate. It doesn't matter where the CU is, it is still treated as an Electrical fitting, so your'e cables are in zone if they are vertical or horizontal from it.
