Electrical Requirements
Electrical Requirements – US and Canada
240 Volt Electrical Installation
All 240V spas must be permanently connected (hardwired) to the power
supply. See the wiring diagram on page 8.
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.
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 or electrical inspector.
Failure to comply with state and local codes may result in re
or personal injury and will be the sole responsibility of the spa
owner.
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 manufacturer’s safety and installation instruc-
tions prior to installation and operation. Incorrect installation may damage
the heater and void its warranty.
