Note: Most installation problems are caused by electrical wiring errors. The most common wiring problem is when the neutral wire from the spa is connected to the Neutral bus in the GFCI. The Neutral wire from the spa should be connected to the Neutral lug on the GFCI breaker. Click here to see an image of this type of wiring error.
