So going back to apprentice theory...I pull a mwbc from a 3phase panel, set three gfi's. Why would I get nusance tripping if I pigtail out the nuetral on each gfi. Won't the GFI electronics strictly compare amperage in on the hot, as to what goes out on the nuetral, regardless of what is going on with the home run nuetral. I know, I know, I'm losing it. Any helpful explanation guys.
