O.K. so I will terminate my EGC on the primary side to a twin lug in the enclosure, jumped to XO,
Biulding steel is my grounding electrode, that will terminate on the twin lug as well.
All that is left is my secondary EGC (there is no nuetral needed so it will not be provided) it seems I have a choice to terminate this on XO or the enclosure frame as well. Does this sound correct? Thanks for all your help.
