As many of us are aware, in relation to permitted routes for cable buried <50mm deep in walls, 522.6.202 says (in part) ...
In a recent thread, it was suggested that, in this context, items of 'current-using equipment' (including large ones - illuminated mirrors and TVs, fixed to walls, were mentioned as examples) qualify as a "point, accessory or switchgear to which cables are connected" and therefore create (potentially enormous) zones in which buried cables may be buried ('Safe Zones').
I have to say that it has never even occurred to me that 'current-using-equipment' (particularly large items) can create 'Safe Zones' in this fashion, and I do find it pretty hard to believe that this is the intended interpretation of this regulation.
What do others think?
Kind Regards, John
