    I am looking at a residential Hot tub being installed on a patio. There is an existing AC unit on the patio. Using the the 2017 NEC as code, does the hot tub have to be a minimum distance from the AC unit? I'm not seeing any specific requirement. Can the Hot tub be located within 3 ft. of the AC? The best I am seeing is 680.22 (D) - requirement that other outlets must be a minimum 10 ft. from a pool as an applicable code section.

    Thanks in advance for any insight you can share.

    The code seams silent on this. Maybe at least 5' so no one could touch the AC when in the water? But I would require the AC to be GFCI protected.
    680.26(B) requires it to be bonded to the equipotental bonding system, but not if there is no metal on the hot tub.

    Hey, please point me in the direction of what code would require GFCI for the AC condenser. I can't find it

    Part of my dilemma is 680.4 which indicates equipment located on the deck shall be installed per 680 and shall be listed. Does the AC have to be listed for use in the pool area? Is the intent to prohibit any equipment not specifically referenced for pool use from being located in the pool area? ( in my case a hot tub area). As an interpretation of intent requirement, I am looking at the lighting requirements that GFI protection is required for lights located 5 ft. or more from a pool.

    Its all about proximity to water, "duh".
    And maybe a little common sense?

    Can't regulate stupid.

    If you have a code section, great. Enforce it. Otherwise, walk away.

    You can give a recommendation if it helps you sleep.

    Here you go, "any receptacles"

    *The National Electrical Code (NEC) ART. 680 Pools and Spas, specifies installation of an approved manual disconnect device. It must be adjacent to the hot tub, at least 5 feet away, and within line of sight. The NEC also requires a 120V receptacle within a 10-20 foot distance from the spa.

    Receptacles Near Swimming Pools and Outdoor Spas and Hot Tubs
    1. Do not locate any receptacles less than (<) 6 feet from the inside edge of all indoor and outdoor swimming pools and all outdoor spas and hot tubs.

    You may locate circulation system receptacles at least (≥) 6 feet and less than (<) 10 feet from the inside edge of any indoor or outdoor swimming pool and outdoor spa and hot tub if all of the following apply:
    (a) the receptacle serves a pump motor or other load associated with the circulation system, and if
    (b) the receptacle is a single locking type, and if
    (c) the receptacle is GFCI protected.


    2. Locate at least (≥) one 120 volt, 15 amp or 20 amp general purpose receptacle at least (≥) 6 feet and not more than (≤) 20 feet from the inside edge of all indoor and outdoor swimming pools and all outdoor spas and hot tubs. Locate this receptacle not more than (≤) 78 inches above the walking surface serving the swimming pool and outdoor spa and hot tub.
    3. Place all receptacles located not more than (≤) 20 feet from the inside edge of all indoor and outdoor swimming pools and all outdoor spas and hot tubs on a GFCI protected circuit.
    4. Place all 15 and 20 amp, 120 and 240 volt outlets serving pump motors, whether by receptacle or hard-wired connection, on a GFCI protected circuit.

    ADAguy, not talking about a receptacle. Asking about an air conditioner. If it a condenser unit or a window AC I don't think there would be an outside receptacle.

    This is an interesting subject because the code does not seem to address an electrical appliance near a hot tub or a pool except for bonding to metal parts.

    Since there is no GFCI requirements for electric pool water heater and no required distance to the pool maybe a AC could be right next to the pool or above it (a window AC) it with no restrictions.

    The AC ???, Condenser?? Most outside AC equipment is weather rated so don't believe the water is a problem, probably not an issue. Shock hazard would be a concern.

    Yes, a "big" one, even if grounded.

    So I am looking at 680.4 and wondering what the intent is since it says:

    680.4 Approval of Equipment. All electrical equipment installed
    in the water, walls, or decks of pools, fountains, and similar
    installations shall comply with the provisions of this article.
    Equipment and products shall be listed.


    So technically speaking, the condensing unit is ON the deck, not IN the deck. ???
