220V Installation
All 220V spas are required to have a dedicated 50-Amp GFCI breaker and should only be wired by a licensed
electrician. To ensure proper wiring of your GFCI, follow these diagrams (Figure 2 and Figure 3).
1. Always follow applicable local, state, and federal codes and guidelines.
2. Your new 220V Cal Spa requires a dedicated, 50-Amp GFCI Service with four #6 AWG copper wires.
This will include a black and a red wire for your incoming power, a white wire used for your neutral and
a green wire for your ground.
#6 AWG wire acceptable for a distance of up to 100'. Wire run over 100' must increase to #4
NOTE:
gauge. Please be aware that this is the only acceptable electrical wiring procedure. Spas wired in
any other way will void your warranty and may result in serious injury.
NOTE: Do not install GFCI breaker in main electrical panel. The further away a GFCI is installed from
the spa, the higher the risk of false tripping or resetting of the GFCI breaker.
C.A.I. can only recommend the use of square-cover Siemens GFCI breaker.
NOTE:
Before each use of your spa, you should check the GFCI. During this test, the spa should be operational.
1. Press the test button on the GFCI. The GFCI will trip and the spa will shutoff.
2. Wait 30 seconds and reset the GFCI breaker (this is accomplished by turning the breaker off then back on).
Your spa will be operational in about five seconds.
3. Your spa is now safe to use.
