Portable cabin wiring

[peeko]

Does anybody know if there's a minimum csa for final circuits in a portakabin type unit?
They're static, used as a site office & canteen - I've got something in my head about 2.5mm2 tri-rated but not got my books with me, am I getting confused with trailers?
These have been done in 1.5 & 2.5 t&e.

Are you talking about the internal wiring or the supply to the cabins.

The internal wiring

What is wrong with t+e for the internal wiring?

 

[westward10]

It is common for site cabins.

Flex only for mobile units, T&E is fine for temporary structure such as Portakabins.
