I have a GE two speed motor/pump for a hot tub that I have adapted for a type of therapy called underwater pressure massage (all of the hot tub jets are channeled through a single hose for the high pressure underwater massage) Recently I took the motor to be reconditioned after it was tripping the GFI. Now the motor runs fine at low and high speeds under normal conditions. However when I switch the hot tub from the regular hot tub jet function to the high pressure underwaterpressure massage it trips the GFI after about 5 seconds. I went back to ask the repair shop for their opinion they said that the high pressure usage should not cause the motor to trip the GFI. Their suggestion; it might that repeated tripping the GFI before the motor was reconditioned may have cuased the GFI to become oversensitive and the Bryant 50 amp 2 pole breaker with GFI may need to be replaced. Is there any way to test this idea? Any suggestions on other things to check?
