Ea) and 1-2/3" 2-#10 (1-220V Cir)& 7 #12 Equipment Grounds conduits run about 100' and then all go into a 12X12 "J" box and then out to fans in flex grouped back together (2-#10 Ungrouned conductor & 1-#12 Equip Ground). Doesn't all wires for a circuit to be a same conduit? What is the code section?
