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

    Cascading the supply to each caravan does have merits, I.e. an RCD at  the source of each and an RCD in each caravan.

    But a 30mA RCD covering the whole site is just adding to risk of injury as folk stumble around in the dark to reset it.

    an installation without them used to be deemed safe, adding an RCD improves the safety but adding another cannot be making much difference and is starting to add other risks.
