    Hi Carol,
    Because of the number of Article Exceptions that are written into the electrical codes, each hot tub project will need to be reviewed individually where all of the environmental factors may be identified as well as the codes that will then apply.
    For example, please refer to NEC sections 680.43, 680.62, and 680.74 for more information, and then make application for your specific area or location.
    I hope this helps,

    Can you confirm what the regulations are regarding a safety cut off switch, or electrical isolator on a hot tub used by the public not just for personal use.

  3. Dave Rongey says:

    Hi Eli,
    A disconnect actually shuts off the circuit power and is required near the hot tub. The circuit must be protected with a GFCI breaker.
    The hot tub itself may have a shut off switch for functions like an air blower etc.
    I hope that helps,

    To hook up a hot tub do I need a disconnect or a shut off switch or both?
    Thanks for time and attention.
