I had an opportunity to buy an inline type GFCI for a song and now have a dilemma. I am powering a 30a Kal clone with a 4 wire input. The problem and question is: The GFI I bought (Woodhead Molex 30053-0M) has 10/3 cords in and out, i would assume 2 poles and a ground, which I believe will work as far as the 240 goes, but how do I get neutral to the control panel in this situation? Are the ground and neutral tied together at the breaker panel? Pardon the dumb question.
