We need to tie the neutral bar in my G.E. main panel with the neutral bar in my generators transfer switch panel. The wire is a #6 gauge copper. There is no room to land this wire in my main panel. I have seen neutral lug kits for SQD panels at the box store that has two stab connectors on it so it can connect to the neutral bar where the individual neutral wires attach. I found an identical item (GE part TGL20) for use in a G.E. panel, but it is listed as a ground lug. It will accept the #6 wire that needs to be landed in the main panel and wonder if there will be an issue using this. I've included a photo.
