Earthing of array (cable size)

[powervan]

the eath is because its a TL inverta! 70% of TL instals in the country have no earth to array But because this was a defo inspection and a pme supply then 10mm g/y from array to rod is a MUST! the idea is if a voltage from panels/cables transfers to array then all metal work on array would have a voltage and you woudnt no till you got up there to work on roof with a nice alley ladder stuck in a wet garden you then grab nearest thing (the array)ZAPPPP ur on the floor! now i cover myself in a body condom (fettish thing) but i am in the minority? and i follow the rules just to keep life simples ! when the rules change (which they will) i wont be running a 10mm G/Y ! lets hope the one time it happens its someone stealing the lead)))))))))))))))))))) then i would call it FUNCTIONAL lol
