Hot Tub GFCI Circuit Breaker Wiring
Hot Tub Electrical Wiring and Installing a GFCI Circuit Breaker: As Described, wiring a GFCI Circuit Breaker for a Hot Tub is not the same as wiring a regular circuit breaker.
Understanding Hot Tub GFCI Circuit Breakers
Electrical Question: I installed a 220Volt 50Amp 2 pole GFCI breaker for my hot tub and it continues to trip.
- The GFCI breaker had two slots for the 2 black lines and one slot for the neutral(white) and then one white wire molded into the breaker (ground).
- I attached the molded white to the neutral bus in the main panel. When I set the breaker it stays for about 5 seconds and then trips.

IMPORTANT: Wiring a GFCI Circuit Breaker for a Hot Tub is not the same as wiring a regular circuit breaker.
- Mike, double check your wiring at the hot tub specifically the connections for the neutral and the ground.
- The hot tub circuit requires a separate neutral and a separate ground wire.
- The neutral wire and the ground wire cannot be attached to the same terminal.
- The GFCI circuit breaker is very sensitive and will trip if the wiring is not connected properly.
- Check the hot tub wiring and the installation.
- Make sure the electrical connections are according to the GFCI circuit breaker requirements.

The Safest Way to Test Electrical Devices and Identify Electric Wiring!The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester, [amazon.com], I use for the detection of Standard Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
