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 9.
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
requirements.
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 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.
Read and follow the heater
manufacturer’s safety and installation
instructions prior to installation and
operation. Incorrect installation may
damage the heater and void its
warranty.
