Can you give me a little more information.
Based on the little information, you are going to have to bring a ground wire along with the branch circuit wiring.
The fiberglass box is not conductive so you will not get a continuous ground by using the RMC.

Along with Don's question, are you checking someone's work or are you planning some of your own?
