GFCI control plug for Caldera Highland Series Spas 2006-current


The GFCI serves an important purpose in any electrical circuit. It provides protection against current leakage to ground, which can cause an electrical shock or in extreme cases, death. For this reason GFCI must always be properly installed and never be removed our altered.

The GFCI measures the amount of current in and compares it to the amount of current oute. The difference between the two values of current is called the current leakage. The difference between the two current values flow down the ground line. When the current leaking to ground is greater than the trip point value (5 mA, plus or minus 1 mA), the GFCI will trip. A tripped GFCI isolates the spa from the line voltage, essentially blocking all power to the spa. Shutting down the spa.


Trouble shooting must be performed to determine the cause of the tripping using a DDM (Digital Multi-Meter).

Diagnostic Panel

Set your DMM on the Ohms scale and perform a current leakage test.

A current leakage test should be performed on all spa at the end of the repair to ensure that the spa is safe to use.
