What electrical service does a swim spa need?

Nearly all swim spas need hard-wired 240V service. Typical requirements: - **50-60 amp dedicated circuit** for a single-zone model, sized to the manufacturer specification for that exact unit. - **A GFCI-protected disconnect** mounted at least 5 ft from the water and within sight of the equipment, which is standard electrical code for spa installations. - **Two circuits** on some dual-zone or dual-heater models, since the swim side and hot side each have their own heater and pumps. Plug-and-play 120V swim spas essentially do not exist; a 120V heater cannot keep a 1,500+ gallon tank at temperature. Get the electrical specification sheet for the specific model before you buy and have an electrician confirm your panel has capacity. Electrical work commonly runs $1,200-$3,500 depending on distance from the panel and whether trenching is required.
