I recently swapped out a 40 amp breaker (previously for an oven/range) to a 30 amp GFCI, on the other end will be a L6-30 receptacle (2 hots, 1 ground). My question is what to do with the neutral wire on either end of the line. In the panel, is it correct to connect both the neutral from the line and the neutral pigtail from the breaker to the neutral bar, leave the neutral terminal on the breaker empty, and then cap the neutral at the receptacle? Or should the neutral from the line be connected to the neutral terminal on the breaker?
Through some research I think I found that GFCI only needs the neutral for 120v loads, just not completely sure
