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,

    A lot of us were brought up on a lot of Urban Myths !

    Not just in Electrics/Electronics - “Put as much salt as you want in the cooking but very little on the meal before you eat it. It`s bad for you sprinkled on the meal!”
