Disconnecting means for motor-driven appliances over what horsepower shall be located within sight of the motor controller?

The correct answer pertains to the requirement for disconnecting means in relation to the horsepower of motor-driven appliances. For motor-driven appliances with a horsepower rating above 1/8 HP, the National Electrical Code (NEC) mandates that the disconnecting means must be located within sight of the motor controller. This ensures that the motor can be quickly and easily turned off in emergencies or for maintenance, allowing for safe operation and preventing electrical hazards.

Understanding the code helps ensure compliance with safety regulations, promoting the protection of people and property. The other horsepower specifications do not align with the NEC requirements, making them incorrect in this context.
