All 240V hot tubs must be permanently connected (hard wired) to the power supply. 120V hot tubs may use GFCI cord, plugged into a grounded outlet. Supplying power to the hot tub which is not in accordance with these instructions will void both the independent testing agency’s listing and the manufacturer’s warranty. |

The power supplied to the hot tub must be a dedicated circuit with no other appliances or lights sharing the power. |

When determining the current, voltage and wire size required for the hot tub configuration to be connected, refer to manufacturer’s recommendations and keep these points in mind:
- Wire size must be appropriate per NEC and/or local codes.
- We recommend THHN copper core wire.
- All wiring must be copper to ensure adequate connections.
- Do not use aluminum wire.
- When using wire larger than #6, add a junction box near the hot tub and reduce to short lengths of #6 wire between the junction box and the hot tub.
