I am running a new 20A circuit to an unfinished basement bathroom. I am also running my #12 hot, neutral and ground through 1/2" EMT conduit. The conduit, I realize is a functioning ground. However, here is the question. When the wires enter the metal boxes for switches and outlets, it would make sense that if I didn't have a ground wire, the metal box attached to the conduit would act as a ground itself. When the conduit connects with the plastic housing of the exhaust fan wouldn't the ground be broken due to the insulating nature of the plastic? This is why I ran a ground to connect to the ground of the fixtures and this exhaust fan.
In my breaker box, there is one ground wire, I think a #6 or possibly #4. That is supposed to gound the circuits, but as you can hopefully see, I was concerned about the absence of adequate ground for the plastic housed fixtures.
Am I wrong? Should I just run a hot and neutral in this case?
Thanks for replys, as always!
