I need to add GFI to an existing 240V 30a30A circuit your use an electric home brewing system. The system uses an electric heating element that is immersed in a kettle of water. The manufacturer recommends the use of GFIC for safety.
Will a two pole 30a-pole 30A GFI breaker function correctly on a three line circuit? How should the neutral pigtail be wired?
Thanks for your help, Fr8Dog
