2-Pole GFCI

[Little Bill]

I heard someone asked the question, "If the neutral is lost on a MWBC, would the 2-pole GFCI breaker trip?
I say no, but something may get damaged due to 240V being unevenly split, causing one load to get over 120V.

I agree. As long as all current is flowing back through the GFCI, it wouldn't trip.
