What is the maximum distance a 125 volt, 15- or 20 ampere service receptacle may be installed from an outside hot tub?

The maximum distance a 125-volt, 15- or 20-ampere service receptacle may be installed from an outside hot tub is determined by the National Electrical Code (NEC). According to the NEC, a receptacle that supplies power to a hot tub must be installed no more than 20 feet from the hot tub. This requirement ensures that users have easy access to power while maintaining safety standards.

If the receptacle were placed too far away, it could lead to the use of extension cords, which pose safety hazards in wet conditions typical around hot tubs. The 20-foot distance allows for proper wiring practices while ensuring user convenience, aligning with electrical safety standards.

This regulation reflects a balance between accessibility and safety, promoting proper installation practices in residential settings. It ensures that the installation complies with the NEC and addresses potential risks associated with electrical supply near water sources.
