So we use A LOT of variable speed pumps for our clients. Primarily Hayward VSP3400. We constantly have GFCI breakers for either the pump, or the low voltage (14v) transformer tripping. The pump manufacturer has admitted they tend to have this issue recently and are working on a fix for it. They claim that when the motor ramps up/down, it's "dirty" and has a lot of line noise causing the breaker to trip. Also, as the lights are changing colors, they turn off/on repeatedly until the proper color or light show is reached. There doesn't seem to be a common denominator. Sometimes the pump breaker will trip (often when the motor isn't even running), and sometimes the light breaker. Both breakers are Class A.
I suppose this is actually two questions:
1. Is there anything I can do to prevent this? I've tried separating the breakers, running the lights through the load side of a GFCI receptacle, but cannot get a hold on the issue.
2. Can I use a Class B or C breaker for the pumps? The motors are double insulated and 230v (class C). This is where the NEC is a little tricky.
Any help or advice from anyone would be greatly appreciated! Thanks
