Caravan Park

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?

  • Just looking back through my notes at inspection on a park last month.


    49 static caravan hook up points, 9 RCD's changed due to various reasons, no test button trip, no trip, etc.


    Touring field, 22 hook up points, no unit over three years old, 6 RCD's changed again various faults.


    10.8% failure rate.


    As you say luckily we have a 100mA S type three phase at origin.

    RCD's in each hookup point, RCD's in static vans and touring.
