120 Volt Electrical Installation
Testing the GFCI Breaker
All 240V spas must be permanently connected (hard
wired) to the power supply. See the wiring diagram
on page 6.
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 NEC
70 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 fire or personal injury and will be
the sole responsibility of the spa owner.
The power supplied to the spa must be on a dedicated
GFCI protected circuit as required by NEC 70 with no
other appliances or lights sharing the power.
Use copper wire with THHN insulation. Do not use
aluminum wire.
Use the table below and on the next page to determine
your GFCI and wiring requirements.
Wires that run over 100 feet must increase wire gauge
to the next lower number. For example: A normal 50
amp GFCI with four #6 AWG copper wires that run
over 100 feet would require you to go to four #4 AWG
copper wires.
One Pump Control System uses a VS300 control box
and requires one 40 amp GFCI and four #8 AWG
copper wires. Two Pump Control System uses a 5100
GFCI and Wiring Requirements
Always follow applicable local, state and federal codes
and guidelines.
Use only a dedicated electrical line with a 15 amp
breaker.
Cord-and-plug connections may not use a cord longer
than 15 feet (4.6 m) and must be plugged into a
dedicated 15 amp GFCI connection (NEC 680.42(A)
(2)). Do not use extension cords!
Always use a weatherproof-covered receptacle.
Receptacle shall be located not less than 5 feet (1.5
m) from and not exceeding 10 feet (3.0 m) from the
inside wall of the spa. (NEC 680.43(A))
Do not bury the power cord. If your cord becomes
damaged, replace it before next usage.
All 120V spas must have a GFCI. This can be either a
15 amp GFCI receptacle or a 15 amp GFCI cord and
plug kit as shown (CKIT110 - P/N ELE09700087).
Testing the GFCI
Test the GFCI plug prior to first use and periodically
when the spa is powered.
1. Plug in the GFCI into the power outlet. The
indicator should turn on.
2. Press the TEST button. The GFCI will trip, the
indicator will turn off, and the spa will stop operating.
3. Press the RESET button. The GFCI will reset, the
indicator will turn on again, and the spa will turn
back on.
The spa is now safe to use.
If the GFCI trips while the spa is in use, press the
RESET button. If the GFCI does not reset, unplug the
spa and call your local Cal Spas dealer for service. DO

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