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 9.
When installed in the United States, the electrical wiring of this spa must meet the requirements of National Electric Code, ANSI/NFPA
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.
