Sundance Spas 850 Series - Manual (Page 8)

Important!
If installed in the United States, the electrical wiring of this spa must meet the requirements of the National Electric Code
(NEC) and any applicable state or local codes. The electrical circuit must be installed by an electrical contractor and
approved by a local building/electrical inspection authority.
Electrical Setup Before Delivery Of Your Spa
1. All 240V spas must be permanently connected (hard wired) to the power supply. All 120V powered models (Denali, Metro, and Tacoma) must
use the spa’s provided 10 foot GFCI cord plugged directly into a dedicated grounded wall outlet or must be hard wired. Never lengthen the
supplied 10 foot GFCI cord or use an extension cord with it for any reason! If the spa is to be located greater than 10 foot from a dedicated
grounded wall outlet, the spa must be hard wired. See page 16-22 for specific power supply requirements by model. Supplying power to the
spa 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 spa must be a dedicated circuit with no other appliances or lights sharing the power.
. To determine the specific configuration for your hot tub’s power connection, refer to Power Supply Requirements on pages 16-22.
•
Wire size must be appropriate per NEC and/or local codes.
• Wire size is determined by length of run from breaker box to spa and maximum current draw.
• 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 (10mm 2 ), add a junction box near the spa and reduce to short lengths of #8 (8.4mm 2 ) wire between the junction
box and the spa.
. The electrical supply for the hot tub must include a suitably rated switch or circuit breaker to open all ungrounded supply conductors to comply
with Section 422-20 of the National Electric Code, ANSI/NFPA 70. The disconnecting means must be
readily accessible to the spa’s occupant but installed at least 5 feet (1.5 m) from the spa water.
. The electrical circuit for the spa must include a suitable ground fault circuit interrupter (GFCI) as required
by NEC Article 680-42 (See illustrations on the following pages for the proper wiring configuration for your
spa model).
