Preparing for Your New Portable Spa

Electrical Set-up Before Delivery of Your Spa

When installed in the United States, the electrical wiring of this spa must meet the requirements of National
Electric Code, ANSI/NFPA 70-1999 and any applicable state or local codes. The electrical circuit must be
installed by an electrical contractor and approved by a local building / electrical inspector.
All 240V spas must be permanently connected (hard wired) to the power supply. 120V spas may use a G.F.C.I.
cord, plugged into a dedicated grounded outlet. Supplying power to a spa which is not in accordance with these
instructions will void both the independent testing agency listing and the manufacturer's warranty.
The power supplied to the spa must be on a dedicated circuit with no other appliances or lights sharing the
power.
To determine the current, voltage, and wire size required for the spa configuration to be connected, refer to the
following:
• Wire size must comply with NEC and / or local codes.
• Wire size is determined by length of run from breaker box to spa and maximum current draw.
• We recommend copper wire with THHN insulation.
• All wiring must be copper to ensure adequate connections. Do not use aluminum wire.
• When using wire larger than #6 (10mm2), add a junction box near the spa and reduce to short lengths of #4
(10mm2) wire between the junction box and the spa.
The electrical supply for the spa must include a suitably rated switch or circuit breaker to open all ungrounded
supply conductors to comply with NEC Section 422-20. The disconnection point must be readily accessible to
the spa's occupant. Check with local municipalities for additional code requirements.
The electrical circuit for the spa must include a suitable GFCI as required by NEC Section 680-42.
