I am adding some circuits to my detached garage/workshop. The original wiring is all in 1/2" EMT. The circuits I will be adding will be from the main box and will use 1/2" flexible non-metalic conduit. My question concerns the ground wire. Since the ground wire is basically a "safety" conductor, is an individual ground wire required for each circuit or can one ground serve multiple circuits? I notice that the electricians who wired the garage provided ground wires within the conduit and did not rely on it for a safety ground path.

One ground wire per conduit. Use for multiple circuits, yes.
