@RDspaguy yes, it’s tripping both. This has been happening only since the new pump was installed, not before. The only strange noises were last year from the pump but sounded much better this year, assuming it’s because it was so close to dying!? Takes about 10 mins to trip. Don’t think there’s anything else on the circuit except an outdoor light but haven’t turned it on at the same time as the hot tub. We have been using this circuit for 5 years and had no issues, plus tried other circuit and it still tripped the other breakers as well
