caravan park distribution setup

[chrisfs150]

I've been asked to wire a caravan park up so far the system consists of:
connection boxes with each socket on a 16 a trip 30mA rcd
SWA to each conn box buried to 600mm+
Incoming supply is t.n.s
But....The main distribution board is 3phase so do I have to have the distribution cct on mcbs alone (1 for each dist cct)
Or doe each cct need to be on a 100ma rcd? If so that ain't going to fit my 3 phase board so do i now need to come from my 3phase MCBs out to a separate board holding my 100ma RCDs then out to my ditribution ccts? Or is it possible to get 60/80a rcbos that will fit?

you don't need to protect SWA with a RCD. main concern is what sizw SWA? ccc? Volt drop calculations?

Special locations in Regs? An easy read

Ahh the old "spatchcock", leaving me special messages in the "reasons" section eh.....

I think you should get an electrician experienced in this field in to have a look at the work fella. It would appear that it's been a while since you picked up a regs book and could potentially learn a lot from someone who has done this type of work before.

This isn't a dig at all, but the question alone leads me to think that you're slightly out of your depth. If this were a Electrical Trainee posting this question, they'd be getting hammered right about now!

everybody specialises in a couple area's for example with is we do a lot of bms, controls etc.

have never set up a plc etc so if I ever needed to I would call in a favour from a guy ive done some work for in the past.
