ah, 250-32, my favorite code!
but wait!
lemme see, 10-2 w/g per 225.39(b) 30A, 2 circuits max, ok that seems Kosher assuming a 2-cir can....so.....unless this is ONE 30A circuit for a welder, we run a G-rod from the noodle bar
of course the #10 could be for V-drop, and is for a 20A branch no OCPD's ?
frodo,
straighten us out here please!
