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

    There really should be a regulation banning two 30mA RCDs in series the same circuit.


    The first thing I'd do is remove the one at source, or replace it with a 100mA delayed trip device.


    We go to endless trouble trying to achieve discrimination along an electrical system then allow this sort of thing!


    And, yes, in the old days. a caravan used two thirds of nothing as the whole thing was powered from a battery storing 1kWh that needed to last several days. Now, with electric fridges and car chargers it might be different. Maybe provide for charging cars separately.
