What options are there for wiring 3-compartment floor boxes in a raised access floor? obviously the best job is usually going to be in an electrak type system....problem....expense, the busbar is not exactly cheap and the tap offs are over twenty quid each.
Another option is trunking and flexible conduit, but what regulations apply to using twin and earth fixed to the pedestals? or laid on cable tray....over to you

Theres nothing against you cable tieing it to the pedestals, unless someone can tell me a reg it contravenes??
I would say this is the most common method I come across

The only floor boxes i have been involved with were in a 2ft x 2ft square modular suspended floor with the boxes cut into the square where needed.

All cables run in kopex.

To be honest, if its a new install, then there isnt really any other way than using the trak.
