Ians, there is a Sans 10142-1-2 i think it is which is the proposed and draft standard for PV stuff. I will try find exact number as it is on laptop. But that is a good starting point and i have matched a bunch of it with the European standards so I feel that book is not to far.

Once I get to the PV green card thing will ask them about that draft and if following international standards perhaps the way. Tbe IEC stuff.

I feel PV is very happy go lucky still with one side thinking its a DIY and another trying to do it by the book in which there is no effing book....
