Doesn’t trip the GFCI Spa Pack, doesn’t trip the 40amp supply, doesn’t trip the 100amp main in the sub panel, trips the 100 amp in the main house panel. I changed it out today cause I thought the breaker was faulty and it did it again.
Spa starts up and runs fine for 30 minutes. Took the spa from 47F to 51F and then tripped. I didn’t time it exactly (unsure if something in the circuitry is being called for and then it trips. I’m an electrician so I’m taking my Ammeter to the cottage hopefully tomorrow and going to trace everything up, take notes and times everything occurs.
