James,That's why I would go with the 30 amp Siemens from Home Depot.
Based on the manual, I would use the Siemens 15 Amp Double Pole Type QPF2 GFCI Circuit Breaker.
[end edit]Siemens GFCI circuit breakers are UL Listed and CSA Certified as Class A devices. These circuit breakers offer the new Self-Test and Lockout feature as required by UL 943, enabling the GFCI to automaticallywww.homedepot.com

If going w a 30amp breaker for a hayward VSPump, doesn't that raise the mA threshold higher than rated for that pump, thus leave it exposed to potential damage for not shutting down when to much noise from the harmonics is supposed to flip the breaker? If the board design has any issues, that could potentially cause it to keep working and then malfunction at a much higher mA threshold along w more heat too. thanks
