Hot Tub Wiring Requirements

Most hot tubs need a dedicated 240V, GFCI circuit to safely provide them with the power they need to run. As a result, you’ll need to make sure your home is running on at least 100 amp service. Most homes built in the last 30-40 years meet this requirement, and many modern homes even exceed this with 150-200 amp service. That said, if you live in a historic home in the area, you may need to upgrade your electrical service before any hot tub wiring is done. At Kolb Electric, we can perform what’s known as a “heavy up” to get your home’s electrical service where it needs to be before we install your hot tub.

Hot Tub Installation Safety Precautions

  • Don’t install your hot tub under power lines – this is unsafe and in violation of the National Electrical Code.
  • Avoid using under underground wiring for outdoor hot tub wiring. If space restrictions don’t permit wiring at least five feet away and underground wiring is necessary, your hot tub should be installed in a rigid metal conduit, intermediate metal conduit or nonmetallic raceway system listed for direct burial.
  • Don’t install low-voltage lighting within 10 feet of the hot tub, even if it is GFCI protected.
