Which NEC section covers the motor disconnecting means?

• A. 430.104
• B. 430.109
• C. 430.110
• D. 430.112

Answer: (B)

The idea being tested is where the NEC specifies the rules for placing the motor disconnecting means. The motor disconnecting means is addressed in NEC 430.109, which directly covers the location and accessibility of the disconnecting means for motors. This ensures the disconnect can be reached quickly and operated safely for servicing or emergency shutoffs, without being hidden behind panels or obstructed. The other sections listed deal with related motor circuit topics but not the location requirement for the disconnecting means, so they do not satisfy the specific rule being tested here. In practice, if you need to verify where the disconnect should be located, 430.109 is the go-to reference.
