Attatched I have something i made on paint which shows multiple caravan points needing a 32 amp supply. The 3 phase board is there in the bottom right.
I was wondering what would be the best way to supply each point using all 3 phases and taking into consideration length of cable and the size. My thoughts are that a 25mm cable should be used to supply them but im really stuck on which route would be the best.
Another question I have is can I earth the metal sheath of the armour at the main board which is PME and then loop the earths inbetween each point? Or does this go against a reg somewhere because then in each point you have PME on the metal sheathing of the armour but TT going into the caravan points?
If anyone can show me using paint what you think the best route would be I would be greatful. Thanks
