Hot Tub Electrical Requirements
We study here the hot tub electrical requirements. Go here to install a hot tub on a deck, where we analyze also other requirements referred to the structural loads.
- You’ll need a nearby electrical source to power your spa – and a licensed electrical contractor to do the work. Determine whether you or your builder will be responsible for hiring the contractor, obtaining permits, and ensuring all necessary electrical work is completed appropriately.
- Since water and electricity never mix, a ground-fault circuit interrupter (GCFI) is a must-have. This device will shut down the system immediately if it detects a change in current flow.
- Some smaller spas can be plugged into a GFCI-protected 110v/20-amp outlet. Larger units usually require a 220v/50-amp connection to work properly.
- A nearby emergency shut-off (usually within 5-15 feet of the unit) is also required by code.
- Plus, if your tub will be sitting on a concrete slab, the electrical wiring must be run in conduit and placed before the concrete is poured.
