Understanding Hot Tub GFCI Circuit Breakers
[ad#block]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.

Is it code for a 220 volt hot tub to have a GFCI protected circuit in California?
Hi Carlton,
Yes – A Hot Tub or any type of Sauna, Whirlpool Tub, Pool, or any such equipment that involves water, electricity, people or livestock, is required to have a GFCI protected circuit. Additionally, the installation of the electrical circuit and all associated components must be installed according to applicable codes, with a permit, and inspected, as required by your local building jurisdiction.
I hope this helps,
Dave
