I attempted to install GFCI protection on a Hayward pool pump the other day using a Cutler Hammer BR GFCI breaker. The pump is computer controlled and would go through the pre-startup sequence with no problem. However, as soon as the pump itself tried to start, the GFCI breaker would trip with a ground fault. After consulting with Hayward, I discovered that they require that a Siemens GFCI breaker be used to provide ground fault protection, but they could not or would not say why. The pump works fine with a Siemens QF220 GFCI breaker.
Can anyone shed some light on why a Siemens breaker works and a Cutler Hammer breaker does not when both at ID'd to trip with a 5 ma fault?
