Electrical Requirements
Electrical Requirements – US and Canada
240 Volt Electrical Installation
All 240V spas must be permanently connected (hardwired) 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.
This is the only acceptable electrical wiring procedure. Spas wired in any
other way will void your warranty. See the wiring diagram on page 11.
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 copper wire with THHN insulation. Do not use aluminum wire.
Use the table on the next page to determine your GFCI and wiring require-
ments.
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.
Wire runs over 85 feet must increase wire gauge to the next lower num-
ber. 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.
Read and follow the heater manufac-
turer’s safety and installation instruc-
tions prior to installation and operation.
Incorrect installation may damage the
heater and void its warranty.
