32a busbar feeding floorboxes

Should the busbar be fed via an rcbo or not

I remember years ago all underfloor busbar trunking / tap-offs to floor boxes were always fed from MCB's. The main issue related to earth leakage from the old CRT monitors.

With the current regs I would always supply via RCBO as the big problem from a design side of things is users plugging in phone chargers, desk fans and I've seen hair straighteners!

I'll go with Malcolms design here, you don't compromise half a computer suite on the basis that someone might plug in some hair straighteners, phone chargers or a desk fan (which are all probably class II anyway).
