Thanks for all your replies...
Dana, great idea, I'll try it sometime in the future, but this isn't a new roof.
Anyway, we came up with a solution for the 150A 3 phase panel.. we mounted 2 pieces of deep strut on the front of a panel and extended it out beyond the RTU, enough to mount the panel on spring nuts, worked great!..lets see if the inspector likes it!
Thanks again..
Brian
