Review on ⚡ Enhancing Electrical Safety with Siemens QF220A Ground Circuit Interrupter by Aaron Parish

Required item if you have a Pentair Superflo Variable Speed Pool Pump. I spent a lot of time troubleshooting installing a new pump as the Eaton/Cutler Hammer GFCI kept shutting down with no apparent true error. It turned out that there was electrical interference in the engine that was causing a false alarm. who knew Well, Pentair knows, but they won't tell you! And many other customers and electricians noticed that after installing the pump. Or better yet, repair your product so this isn't a problem! After several calls to Pentair support I ordered this switch as it was not available in my area. Siemens GFCI has fixed the false positive problem. At least for now. Has been working for a week now with no problems.
