Pentair Pool Pump GFCI trips

I just completed a install of a 230V pentair vs pump and this thread had me seriously worried I'd be tripping the GFI.

I ended up having to install a boost transformer to get from 208v to 232v. Could this have anything to do with why the QO gfi installed has (knock on wood) is working without issue?

You're not isolating with a boost so I don't think that would change anything.

I've installed some QO breakers also that don't have nuisance trip issues that I'm aware of.

They weren't engineers just sales and management. The only thing they found was an Intermatic pool light transformer that they suggest was the cause of the nuisance tripping and suggest use of the Pentair transformer. I can confirm that switching the lights on and off repeatedly caused the Siemens 120v, 20a, GFCI pool light and outlet cb to trip while I was there. The 240v, 20a gfci Pentair pump breaker hasn't tripped like the Siemens did.

any new news??


why do they have a 6mA "special" ocpd
from their intelliflo manual

Pentair offers 2-Pole 20 Amp GFCI breakers(P/N PA220GF) which offer 6 milliamp personnel
protection while meeting 2008 to current NEC
Standards for Pool Pumps.

6mA is at the top/end range of class-A UL943 range.
my guess is perhaps real or induced leakage that trips ocpd that are tuned on the low side ??

Nothing new. The manual, catalog and tech support all tell that lie to sell the breakers aparantly.
I have emails from Pentair and Siemens stating the breakers are the exact same except for the labeling.
