Question:
Dear Code Question,
If I have a 3-phase, 3-wire, corner grounded delta system, is there a rule in the Code for identification of the grounded phase?
Thanks for any help you can provide.

Answer:
Hello Ed,
Based on the information in the question, there short answer is yes. Section 200.6 requires grounded conductors to be identified by using the colors white or gray, or by one of the other identifications means mentioned in either 200.6(A) or (B) depending on the size of the grounded conductor.
