My Pentair HP 900 pool heat pump runs for a little while (15-60 minutes) and then trips the breaker. Any idea why this is happening?

should be a 60 amp breaker

GFI devices are prone to degrade over time. Also, when used outdoors there are additional moisture issues that may cause sufficient current leakage to trip the breaker.

I had a similar problem this Spring. I was using a 20 amp GFI "master" outlet that protected two additional outlets 'downstream' of it (wired to the 'load' terminals on the GFI outlet- I'd have the check the doc. to see what terminology was used here). The pump was plugged into one of the downstream outlets.

Replacing the GFI seemed to solve the problem. I did ante up $20 for an 'outdoor' model of the 20 amp GFI unit, several bucks more than the standard 'indoor' unit - have no ideal if that represented additional value or not.

Note also, that this is the third such pump I have used for my pool cover. The other two failed to come on at all after about a year's use. The mfg replaced them under warranty (I may have had to send back the old pump - I forget!).

If the seals are damaged, water will leak into motor section and cause GFI to trip and yet the pump will seem that it is running fine if plugged into a non-GFI receptacle
