Which article regulates the disconnecting means for motors?

The regulation surrounding disconnecting means for motors is specified in Article 430.102(B)(1) of the National Electrical Code (NEC). This section details the requirements for disconnection means that ensure safety and accessibility for motor circuits. It emphasizes that there must be a means to disconnect the motor from the supply circuit for maintenance or in emergency situations.

This article specifies the necessary conditions and location for the disconnecting means to ensure it is readily accessible and capable of being locked in the off position. These provisions protect workers and technicians by allowing them to safely service motors without the risk of accidental re-energization.

The other options refer to different categories within the NEC. Article 440.15 pertains more to branch circuits that supply motors, while Article 410.30 addresses fixture wiring requirements, and Article 450.29 deals with the protection of transformers. Thus, they do not specifically cover the disconnecting means for motors as directly as Article 430.102(B)(1) does.
