Hi, looking for some advice for supply to static permanent caravan at bottom of garden.
My House supply is TT. From what I can gather from previous thread s, is this acceptable.
House end, SWA terminated into plastic ad.box and l+n tails into non RCD side of cu, from suitably rated MCB. Armour not connected, neither is SWA earth (it's a 3c 6 xlpe).
Caravan end. SWA terminated into box and tails into standard existing cu, which is RCD protected for caravan ring and lights. Earthing to separate rod beside van, and everything cross bonded at this end to give a local TT.
Do I bond armour at all, if so which end(s)?
Does the 3rd core in SWA effectively become redundant, as don't want to export/extend earth between house and van as 30m and also soil conditions very different.
I've attached pics of both ends.
Thank you.
Craig.
