How does the NEC define the term 'in sight' for a motor disconnect?

The term 'in sight' as defined by the NEC (National Electrical Code) refers to the visibility and distance requirements for a motor disconnect. The correct understanding is that 'in sight' means the disconnect must be visible and not more than 50 feet from the motor it serves. This requirement ensures that operators can easily locate and access the disconnect in case of an emergency or when maintenance is needed, promoting safety in the electrical system.

The distance stipulation of 50 feet provides a practical range that allows for a clear line of sight to the disconnect, ensuring that anyone operating or working near the motor can quickly react if needed. This visibility is fundamental in preventing accidents and enhancing electrical safety standards in residential wiring practices.

Other options may suggest different visibility distances or conditions for being in sight, such as obscured locations or specific distances that do not align with NEC standards. Understanding this definition helps enforce safe wiring practices in residential electrical installations.
