Calculating Cable Size for Ring Circuit

[Dillb]

Blah blah blah

I'd be suggesting to the customer they invest in getting a consultant in to do a proper spec.

They have, heres the address for them.

Just out of curiosity, why SWA for wiring the sockets?
How to you terminate the armour?
If it is 6mm then you will have fun putting 2 of them into each socket.

It would depend upon the make, but 6mm would be the limit for termination in box and terminals

Run a suitably sized sub main, in a roughly central position in the stadium, fit a suitably sized distribution board and wire your radials/RFC s from there, still can't understand why you are saying the sub main will need to be sized there and back.

a 25mm SWA is needed, which obviously inst viable for a few sockets.

Why not, I once installed a 35sq cable for 1No 13A double socket (Fridge and kettle) to a fishing/hunting lodge over approx. 200m.
The owner thought less hassle than continually getting fuel for a generator! So eventually paid for itself.

Possibly run more than 1 sub circuit. 3 phase or 1 phase Sub circuits to be suitably sized for known load plus spare capacity for unknown (with -in reason) load. I would keep all the final sub circuits to a sensible distance. Possibly use 16 amp sockets for caterers to plug into. As mentioned before, I would get a spec to say to what is required. You may leave yourself wide open later on being sued, if not adequately designed.
