[QUOTE="ProDave, post: 229530, member: 6969"] so 200 amps (total) supply and 60 pitches = 3.33A per pitch. Now they are not all going to be on at once, but I would say a 6A MCB at each outlet should "solve" the problem. I'm betting it's 10A or 16A at the moment? I'm assuming (because of the time of year) these are static van's, not tourers? If so that supply is wholey inadequate, and the site should stump up for the 3 phase feed. Even that 300A (effectively) over 60 pitches is only 5A per van which IMO is still not enough. But to solve the immediate problem, I think the only reason for the 100mA RCD is the TT supply. Can you ask if the DNO will provide a PME earth? If they can, you can dispense with the 100mA troublesome RCD as you will have an RCD at each pitch outlet. You should still TT each outlet, but having the (presumably burried SWA) protected by a PME earth (in fact anything other than TT) means you don't need RCD protection on them. [/QUOTE]
