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

    Table 4D4A RM D => 46 A for SP 6 mm2 SWA. As BOD suggests, an ordinary domestic ring has a "mark up" of 1.6 x so if that is applied, we get to 73 A. So a 63 A OCPD is appropriate.


    Diversity will sort out the rest. ?
