I'm looking into installing serviced pitches for a campsite venture (actual location undecided) and have two (probably many more!) problems, 1. Never done it before and 2. Haven't got round to doing my 17th and understand changes have occurred since I did 16th.
I've been through 16th to think out the basic design and researched what I can with regard to 17th in case of changes but still have some questions and any pointers would be well received :O)
According to regs each pitch supply (they want 10 for starters) has to rated to 16A, individually protected and no diversity allowed (as they are effectively plug skts). The Isolator needs to be near the pitch so I'm thinking each pitch should have a small cubicle with RCBO, BS 60309 socket and a courtesy lamp cos I don't want chilly, wet campers sticking their little pinkies anywhere they shouldn't in the dark. I think these cubicles can be fed using SWA (csa tbd) buried >500mm going back to a CCU type of thing.
Q1. Above sounds reasonable?
Q2. Should SWA armour be bonded?
Q3. As each pitch will have isolation at the pitch but be fed from CCU should I protect those cables runs individually at the CCU (with a Main Isolator as well) or should I protect all of them only with a single Main Isolator?
Q4. Assuming all 10 pitches came off single CCU would I really need a 160A Main Isolator?
Here's where I get a bit confused about the 'rated at 16A' quoted from regs. Providing 16A per pitch adds up to a lot of incoming supply if no diversity is applied anywhere. I always thought pitches only got about 4-6A and 10A if it's a good site! Can I put in diversity as I think it very unlikely all pitches will be drawing 16A at the same time. I would think 6A should do for most?
Now I get to Main Supply. It seems you mustn't bond to PME supplies so I guess that means if local supply is PME I'd need to make the camping services TT with earth stakes and the like?
That's enough Q's for now. Sorry for long winded query :O)
