Caravan Park

Grobbyman
I have to replace 6 pitch boxes on a touring van caravan  site.

So six pitch boxes with 4 van hookup points per box, each hookup point protected by a 10A 30mA RCCB.

Unfortunately I've also discovered that the site is wired as a ring in 6mm SWA, buried direct in ground.


Any thoughts on max fuse size to protect a 6mm ring?


Regards

    Whilst I have no direct experience of caravan site wiring it's worth while being careful with load planning and management a relative of mine had a caravan on a site where they were limited to 2 5 amp sockets and a few lights per van then after some time people started to unofficially upgrade to 15 amp sockets for kettles wash machines etc. At first it wasn't a problem then within a year or 2 they got the problem of fuse blowing at the site intake this was upgraded unofficially and for many years power cuts became a regular event for the whole area it turned out when the site was busy they were regularly tripping the local pole mounted TX. Even to this day there's a notice warning of evening power cuts. Mapj1 whilst I'm not questioning your expertise I thought it was 35 houses per 400 amp substation fuse  this works out as they reckon 2 kilowatt per house X 35 is 350 amps although at peak times the fuse will be overloaded y a bit. If it was 70 houses I think the fuse would be glowing like an electric fire bar!!
