Why isn't twin and earth cables used in commercial?

Former Community Member
Former Community Member

I was always taught that twin and earth cables should be used in domestic only and singles/multicore in commercial? 

Why is that ? I mean there isn't anything wrong with using 1.5mm2 twin and earth with 1.0mm2 CPC for lighting circuits.

Regards,

    It depends what you mean by “commercial”. As opposed to industrial, I would include shops and small offices, which might even have been converted from housing. Then there are official residences like embassies or palaces.

    What is, IMHO, inappropriate is T&E in conduit (galvanised or PVC).

    Very common in schools, T&E on basket then galv drops to sockets
