how do I test a breaker with a multi meter to determine if it is the breaker or tub controller?
I have a hot tub which is tripping the 50 amp gfi. When I reset the gfi, it trips after 5 or 6 minutes under load. I can add more load (pumps) within the first 1 or 2 minutes and it does not trip. The hot tub repair man said it was the gfi breaker...how do I test the breaker with a multi meter to determine if it is the breaker or tub controller
With a GFI breaker you really cant test it. the trip point is based on a returning ground loop. You can test the amp trip as stated by the other lister below, but that will not tell you if the gfi Portion is bad.
GFIs are a royal pane at times do to the can be bad right out of the box. on hot tubs, pools, and spas GFIs will go bad if you get any type of poor installation, electrical surge, lightning hit close etc.
Chances are that the breaker is BAD.. but refer changing it to a licensed Electrical contractor to to the way they interconnect with the electrical panel.
