Hi Everybody,
Need some advice, have a hot tub (40A) and one of the two pumps was whining so I knew bearings were going so I replaced the two speed pump, also replaced heater element.
New pump is 4.5 A more than old.
GFCI keeps tripping but only when everything is on at once. If I activate pump 1 and both stages and heater , breaker holds. Turn those off and Activate blower, breaker holds, if I activate all at once , it trips. So my thinking is that IF there was an actual ground, when I tried these tests it would still trip when I activated whatever had the ground etc.
So I replaced GFCI with a standard breaker to test for overload, and it holds and never trips.
So.....I amp metered it and it is a 40A GFCI and total load with everything running is 38.5A. Wont trip the regular breaker but maybe GFCI is more sensitive to being near max and heats up and trips? (It takes 30sec to a minute to trip).
So I am thinking its a maxed out circuit issue, so thinking of changing pump to lower amperage.
Can anyone offer another suggestion per chance?
Really appreciate it
