Hi All, I have a touring caravan site that needs 32 x 16A hookups installing. The site has a new 200Kva 3 phase supply. My question is can I run 2 ring circuits in 2 core 35mm2 swa cable (open burried) each with 16 hookups connected? Earthing will be TT at each hookup via a 10mm copper earthing rod with 6mm2 earthing cable. Thanks in advance.
