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?


Regards

  • I am trailing around houses where the electrical installations have not been touched for years and if there is a RCD it certainly has not been tested regularly.


    The initial RCD failure rate is probably in excess of 50%, though many respond to a kiss of life taking the complete failure rate down.
