Electrical Requirements
240 Volt Electrical Installation
All 240V spas must be permanently connected (hard wired) to the power
supply. These instructions describe the only acceptable electrical wiring
procedure. Spas wired in any other way will void your warranty and may
result in serious injury. See the wiring diagram on page 7.
When installed in the United States, the electrical wiring of this spa must
meet the requirements of National Electric Code, ANSI/NFPA 70-2008 and
any applicable local, state, and federal codes. The electrical circuit must
be installed by an electrical contractor and approved by a local building /
electrical inspector.
GFCI and Wiring Requirements
The power supplied to the spa must
be on a dedicated GFCI protected
circuit as required by ANSI/NFPA 70
with no other appliances or lights
sharing the power.
Use one 50 amp GFCI with four #8
copper wires with THHN insulation.
Do not use aluminum wire.
Wire runs over 85 feet must in-
crease wire gauge to the next lower
number. For example: A normal 50
amp GFCI with four #8 AWG Copper
wires run over 85 feet would require
you to go to four #6 AWG copper wires.
When NEC requires the use of wires larger than #6 AWG, install a junction
box near the spa and use #6 AWG wire between the junction box and the
spa.
Testing the GFCI Breaker
Test the GFCI breaker prior to first use and periodically when the spa is
powered. To test the GFCI breaker follow these instructions (spa should
be operating):
Press the TEST button on the GFCI. The GFCI will trip and the spa will
shut off.
Reset the GFCI breaker by switching the breaker to the full OFF position,
wait a moment, then turn the breaker back on. The spa should have
power again.
