Motor Disconnects and Compliance with NEC 430 and NFPA 70E
Motor Controllers vs. Disconnect Switches NEC Section 430.102(B) requires each motor controller to have a disconnect within line of sight from the motor and driven equipment. NEC Section 430.109(A)(6) recognizes that a manual motor controller and disconnect can be the same unit. Hubbell s Circuit-Lock Unfused Disconnect Switches are UL listed as a manual motor controller and also suitable as a motor disconnect and meet these code requirements. In order to comply with the visual verification requirements of NFPA 70E without the need for PPE and FPB calculations, a H.P. rated plug and connector should be used in the circuit between the disconnect switch and the motor. Hubbell H.P. rated IEC pin & sleeve plugs and connectors can be used in conjunction with Circuit- Lock Disconnect Switches to provide a visual verification of disconnecting means for servicing or changing out a plug connected motor. NFPA 70E : When servicing or changing out a plug connected motor, the Circuit-Lock Disconnect switch s red handle must be turned to the Off position and the switch Locked Out per OSHA lock-out/tag-out regulations. Visual verification of motor de-energization requirements of NFPA 70E are met when the plug is separated from the mating connector. Applications where motors are hard wired from the disconnect switch will require some level of PPE and FPB calculations.
Circuit-Lock Motor Disconnect Switches
Modular Power - Linkosity NEC Article 670 on Industrial Machinery refers to NFPA 79-2007, Electrical Standard for Industrial Machinery where sections 14.1.2.2 and 14.1.5.1 specifically indicate that molded connections factory-applied to cable and cords are to be permitted. NEC 336.10(7) Permits type TC-ER cable in transitions between cable trays and the utilization equipment or devices when secured at intervals not more than 6 ft without continuous support. Sealed cable sets prevent condensation building up in raceway and penetrating the motor head
