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

Former Community Member over 2 years ago

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,
