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 alu-
minum wire.
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 opera-
tion. Incorrect installation may damage the heater and
void its warranty.

when the spa is powered. To test the GFCI breaker fol

to the full OFF position, wait a moment, then turn
the breaker back on. The spa should have power
again.
