New single floor office advice please

[Nick Harvey]

Customer will be hiring a qualified sparks, but can anyone give me guidance as to how a single floor open plan office should be wired in terms of circuits?
There will be 3 islands of 8 desks and 3 of 3 desks, each desk served by an under-desk 4/5-way with a Weiland-to-13a lead. 13a sockets will be in 100mm trunking round perimeter, and each desk island hits a wall. How many of the desk supplies can be on a single 30a ring? If the total max load does exceed 30A can they theoretically be on the one ring? Would it be prudent to split into more than one ring? Advice gratefully received! Thanks

assuming computers on each desk, you are limited by cumulative leakage, and should be installing hi-integrity earthing.

welcome ,its down to the spark to design it for the customer ..

I would consider running Radials and use 16A commando plugs and sockets to connect the islands.

Wouldn't install a RFC, a radial for each Work Station would be my choice, with HI earthing as well. Regulation 543.7.2.201 refers, OSG 7.5.3

LOL.

Floor sockets only really work with raised floors.
If there are raised floors, then you could consider Electrack.

Nope - old building. Conventional timber floors

If they are Artichokes they should be able to design an installation, or know someone who can, not a job you can design on the run I should imagine, needs a lot of thinking about, prior to getting the tools out.

The floor might be Larva, only some members will get that.

in case you are not understanding here - nick harvey, there are limits to the floor space that an A1 ring final circuit can cover - however, I would suggest running two radials - down each side of the office in 4mm cable - with a 32a supply to both.

Go on I'll come clean, Larva???????????????
