What is the maximum distance allowed for a motor disconnect to be in sight of the motor controller, according to NEC?

The correct answer reflects the National Electrical Code (NEC) requirement that specifies the maximum distance a motor disconnect can be from its controller while still being considered "within sight." The NEC stipulates that a disconnecting means must be located within a distance of 50 feet from the motor or motor controller to ensure the motor can be quickly and easily de-energized for maintenance or emergency situations. This distance not only accommodates safe working practices but also aids in compliance with safety regulations intended to reduce risks associated with electrical shocks or equipment malfunctions.

Understanding this requirement is vital for anyone involved in residential wiring, as it highlights the importance of accessibility and visibility in electrical installations. It's crucial for electricians to be aware of these guidelines to ensure that motor disconnects are both compliant with the NEC and provide a safe working environment.
