Electrical is not the place to improvise.
Most spas need a dedicated circuit, GFCI protection, correct wire sizing, and a safe disconnect location. ETHT can tell you the model requirement. A licensed electrician should do the work.
The basics
120V means simple. 240V means stronger.
Freeflow plug-and-play models are the simple 120V lane. Most Hot Spring acrylic spas, swim spas, and many saunas need 240V dedicated electrical.
- Freeflow: standard 120V outlet when the outlet is correct.
- Hot Spot, Limelight, Highlife: dedicated 240V circuit by model.
- Endless Pools swim spas: larger 240V circuits, often model-specific.
- Saunas: 120V or 240V depending on model and heater.
Delivery gate
Power needs to be ready before delivery.
A filled spa cannot be tested correctly without proper power. If electrical is incomplete or wrong, delivery may need to be delayed or a return trip may be required.
- Confirm model before electrician work.
- Use the manufacturer guide for the exact model.
- Keep disconnect and panel access clear.
- Send photos if the team asks before scheduling.
