![]() reinforcement metal of the pool, spa, coping, shell, framing, etc.all metallic parts of the pool and spa.General list of the items that require equipotential bonding: Part of the pool to another, and from metallic equipment to the pool Keeping the electrical potential at the same level reduces the hazardĬreated by stray currents in the pool or in the ground around the pool.Ĭonnecting (or bonding) everything metallic in and around the pool will helpĮliminate voltage gradients (or differences in electrical potential) from one This is referred to as equipotentialīonding. Metallic parts to form an electrically conductive path that will result inĮlectrical continuity between components to ensure that the electrical Bonding to perimeter surfaces shall be provided and be attached to the pool, spa, and hot tub reinforcing steel or copper conductor grid at a minimum of four points around the pool, spa, or hot tub. A perimeter surface that extends less than 3 feet and is separated from the pool by a barrier shall require equipotential bonding on the pool side of the barrier. perimeter surfaces that extend 3 feet horizontally beyond the inside walls of the pool, spa, or hot tub.conductive pool shells, including poured concrete, sprayed concrete, and concrete block with painted or plastered coatings.Of pools, spas, and hot tubs must be bonded together using conductors at leastĨ AWG, or using rigid metal conduit, including: Screws must not be used to connect bonding conductors. Run to the equipment grounding terminal in the main service panel. ForĮquipment grounding, a separate insulated copper grounding conductor should be Of metal parts of the electrical equipment makes a low-impedance path for the faultĬurrent back to the source circuit to trip the over-current device. Parts of the pool/spa structure to attain equal electrical potential. To get all metal parts of the electrical equipment and the non-electrical metal Grounding terminal of the pool equipment panelboard and the grounding terminal Have all exposed non-current-carrying metal parts grounded.Īn equipment-grounding conductor should be installed with the feeder conductors between the Wet-niche luminaires supplied by a flexible cord must Installed, the installation of an 8 AWG insulated copper bonding jumper may be Luminaires must be connected to an insulated copper groundingĬonductor not smaller than 12 AWG. Related equipment should also be grounded. They also should be listed for direct burial. Grounding andīonding connections should be made of copper, copper alloy, or stainless steel. Identified as being used for wet and corrosive environments. Grounding and bonding terminals should be transformer and power supply enclosures.panelboards that supply electricity to equipment associated with the pool.all through-wall lighting assemblies and underwater luminaires.all electrical equipment located within 5 feet of the inside wall of the pool water.all electrical equipment associated with the circulation system.In accordance with the NFPA 70 National Electric Code® (NEC®). The pool equipment, a fault could occur and charge the entire pool or spa,Įquipment for swimming pools must be grounded and connected by wiring methods Remember that water isĪn effective conductor of electricity. Open anything that is not required to be opened, especially electricalĬonnections, loose wires and conduits, and water leaks. Visual-only inspection, stick to using your eyes only and not your hands. Workmanship, particularly with the electrical components, wiring and When inspecting the pool or spa, check for unfinished or poor Be sure to identify all circuits that are related to the Don’t stand in water when working with or Be aware of your surroundings when performing an inspection,Įspecially when there are electrical components and water in closeĬomponents without disconnecting them from their power source. Always proceed with caution, and use personal protectionĮquipment. Homeowners to consult or hire an electrician instead of doing any electrical Remember that water and electricity don’t mix. One important aspect with regard to electrical safety is the proper grounding and bonding of the electrical and metal equipment of swimming pools and spas. ![]() However, learning the basic components and functions of residential pools, with a concentration on permanent in-ground pools, will help inspectors recognize defects in their condition and installation. ![]() Standards of Practice, an inspector is not required to inspect swimming pools or spas. According to InterNACHI’s Home Inspection ![]()
