Question:
Hello Code Friends. Can a single pole switch used to open the control power circuit to a three-phase motor starter serve as the required motor disconnecting means? The switch would be located with-in site and less than 50 ft. from the motor. The motor starter would be inside the building at the MCC. Thank you, John Payne

Answer:
Hi John, thank you for the question. In general, the disconnecting means for an electric motor shall be one of the types listed in Section 430.109(A)(1)-(7). The installation you described would not meet the code requirement for an electric motor disconnect.
