Ron,
Pentair sells a special breaker for the IntelliFlo, P/N PA220GF GFCI... It is manufactured by Siemens... It may or may not be identical to the one Siemens sells on the open market...
But.. In several places where I worked over the past 30 years, we would have the manufacturer "cherry pic" components from their normal production line, that fit our specific technical requirements. They would then rebrand them with our P/N... I have seen this done for thousands of different parts...
I have no way to know if this is being done with Pentair's GFCI or not, but I do know that my pool builder is one of the cheapest people alive and he went to the expense of installing the Pentair GFCI... My gut says he would not have done this if he did not believe that it was necessary...
Another thing to look at is that the Pump is supposed to be the ONLY thing powered by the PUMP's GFCI breaker... Many installers use this same GFCI to power other things... In most cases this is not an issue, but in some cases it is.. All it takes is a little noise from a relay to back-feed into the GFCI to pop it...
Thanks for posting,
Jim R.

If your GFCI is popping all the time, then the breaker is most likely not the issue... I'm talking about odd, random and intermittent trips or false trips...
