GFCI for Pentair VS pool pumps

[74sparks]

I think most are aware by now that the Pentair VS pool pumps don't play well with many brands of GFCI breaker. But short of swapping the whole panel out for Siemens, what solutions exist for adding GFCI to a type-CH panel, when upgrading to a Pentair VS pump? A type-CH 220 GFCI breaker has already been tested here, and experienced random trips.

A small breaker panel with a Siemens or Pentair GFCI breaker in it. Feed the new small panel from the existing panel.

Figured that was going to be the path. Is any particular Siemens series favored for VS/VFD motors, or do they all play equally well?

I've seen Pentair PA220GF breakers around, mostly at pool and spa suppliers. But short of their IntelliCenter automation load centers, I don't think I've ever seen a simple 2-space load center from Pentair.

No idea if one Siemens series is better than another for this application. I think the Pentair breaker is a rebranded Seimens, but not sure

I always thought they looked similar, but hadn't noticed how much, until you said that. I'd say we have a visual match... PA220GF for QF220A.

PA220GF:


QF220A:

At least that gives me a load center to shop.

Thanks!
