Thanks for all the comments. I think this job is a bit beyond me, but i'm going to give it a go. Great learning curve as i've never done a job like this. I'll be using 16a electric hookup units (rcbo) Caravan Park Electrical Services - Touring Sites on a ring around the field to connect all 9 units (each suppying 2 caravans, 18 total).
Total length of cable needed will be 250m for the ring and looping in/out of hookup units. The farmer is telling me he has had a design in for the finished park from a caravan site type installation company last year and they proposed to link between caravans with 16mm two core SWA. I reckon 25mm 2core swa would be more adequate allowing for volt drop over that distance. Obviously, I'm worried now because quoting using 25mm swa is going to be a lot more than his previous quote.
Would 16mm be adequate? Help, it's giving me a headache
