Cable types for commercial installation

[chloebear]

Hi all,

is it still acceptable to install singles in galvanised 3 compartment trunking under a raised (computer) floor with tails of either plastic or metal kopex to the floor boxes?? or are we now supposed to use LS0H cable throughout?? this is for a new build office.

Is this installation for a full blown main frame computer suite, or just an office PC area with raised floors??

It's for a general office area with seperate comms room for the server racks etc - so standard office layout of floor boxes with sockets & data outlets. I understand that the lighting above the false ceiling will need to be in LS0H cable, but was unsure about the under-floor cabling.
