Answer: EMT shall be used <600V. Rigid conduit for all MV conductor

14) Situation: Drawing “EG102” on the Power Cabling Feeder Schedule shows all conduit being ran in 4” EMT. On specification “3.4 Exposed Work Installation A” states conduit for conductors above 600V: Rigid steel or rigid aluminum.

Request for Clarification: Requesting information on which to use EMT as stated on Cable Feeder Schedule or rigid steel or rigid aluminum for conductors over 600V (MV-

G2, MV-G2T1A, MV-GTB, MV-G2NGR)

Answer: EMT is allowed 600V and lower. Rigid Metallic Conduit only for MV conductors
