a little more clarification, please
I have two circuits, both are 208/240, 3 phase, 4 wire, 60 amps. They both leave the power panel thru 1 1/4" EMT (8 wires total). The first circuit (4 of those wires) will wire nut at a 6" X 6" metal box and feed A/C unit one, where I will provide a bond between the box and the ground wire for circuit one. The second circuit will "pass thru" the first 6" X 6" metal box and, via 3/4" EMT, wire nut in the second 6" X 6" metal box and feed A/C unit two, where I will also provide a bond between box and circuit two's ground. Am I required to cut circuit two's ground wire in box one and ground it in box one, before sending it on to box two ? I read 250.148, and don't belive it requires me to, my business partner thinks otherwise.
