A Cape Coral homeowner bought a new HotSpring hot tub from the Hot Spot collection and needed power to it. We installed a new outdoor sub panel on the back exterior wall, fed from the home’s indoor main panel.
- Location: Cape Coral, Florida
- Service: hot tub (spa) electrical installation
- Equipment: Square D QO sub panel, HotSpring spa panel, 50-amp GFCI circuit, 20-amp GFCI shed circuit
What we did
- Installed an outdoor sub panel fed from the home’s indoor main panel.
- Installed the spa sub panel that came with the new HotSpring spa, next to the new sub panel.
- Protected the spa with a 50-amp GFCI circuit, connected it, and left it running.
- Ran underground conduit from the new sub panel to the shed in the backyard for lighting, on a 20-amp GFCI circuit.
Why a hot tub needs its own protected circuit
A spa combines a large electrical load with water and bare feet, so it gets its own dedicated circuit with ground-fault protection and a disconnect within reach of the tub. That is the reason the spa came with its own spa panel, and why the breaker labels in the photos show the spa and the shed separately.
Other circuits from a sub panel
The same approach works any time you want to add circuits off your indoor main panel: spas and hot tubs, saunas, a garage sub panel, or a shed or backyard building. Learn more about hot tub circuits, or request a quote for your backyard project.
