Why Does My Hot Tub Stop Working
My Hot Tub is Tripping Off, is the Wire Size Right?
Hot Tub Tripping the Breaker
[ad#block] Electrical Question: My Hot Tub is Tripping Off, is the Wire Size Right?
My hot tub breaker keeps opening. After a year of operation (with some breaker trips) the hot tub tech now says, I’m not getting enough power to the hot tub.
The hot tub is 125′ from the panel and my exterior 2 pole 50amp circuit breaker is wired with #10 AWG direct burial wire.
Do I need to upsize the wire if the distance is too great?
This electrical wiring question came from Mark, a Handyman in Washington.
Thanks for your electrical wiring question Mark.

Electrical Wiring for a Hot Tub
This electrical wiring question is about an Electrical Problem with a Hot Tub in the Back Yard of a New Home.
Hot Tub Wire Size
Reviewing the Electrical Question:
- My hot tub breaker keeps tripping off. After a year of operation (with some breaker trips) the hot tub technician now says I’m not getting enough power to the hot tub.
- Mark, from the information you have provided, The wire size to the hot tub is undersized because #10 wire is rated for 30 amps. Therefore this condition is a potential hazard and is not NEC code compliant. You should seriously consider turning the circuit to the hot tub off and not used it until the required wire size has been installed.
Consult the installation manual for your specific hot tub which will describe the minimum wire size.
For example many hot tubs require #6 AWG copper wire for a 50 amp circuit specification, however the actual wire size depends on the electrical equipment that is installed as part of your specific hot tub.
If the total distance from the main electrical panel to the hot tub is greater than 200 feet then the wire size should be increased.
