How can I tell if my spa needs 2 wire or 3 wire between pump

Customer Question

How can I tell if my spa needs 2 wire or 3 wire between pump and GFCI?
I have a "wild water" spa (used, no manual, disconnected when I acquired it) and have been unable to find any information on it.

My name is ***** ***** my best to answer your question and resolve your issue.
Most hot tubs use 3 wire w/ground. There are some brands that do not use a neutral wire, however, I am not personally familiar with Wild Water to be positive.
If you send me some pics of the control box, circuit board, and/or the wiring schematic I can give you detailed help. The wiring schematic usually is on the back of the control box cover/lid.
Older tubs use wire nuts to connect the wiring sometimes, but most use some sort of terminal block. This may be in the box or directly on the circuit board. Most of these are labeled:
Line 1
Line 2
Ground. Sometimes the ground is to the box.
If there is a LABELED neutral terminal connection in the box or on the board, then you will need 3 wire. If no neutral is needed, you will see a obvious missing neutral labeled connection at the terminal block.
Most tubs require 3 wire, 6 gauge with a 50amp gfci breaker.
