Dual-pole GFCI Breakers used in 220 circuits

I was reading about installing GFCI breakers in panels. You connect the nuetral from that circuit to the breaker along with the hot and then the pigtail white from breaker to nuetral panel.

So, if I do a 220, dual pole circuit (2 hots and a ground where there is no nuetral connected) how is circuit GFCI protected??? AM I thinking about this the wrong way?

If there is no neutral used by the load, then no neutral needs to be connected to the GFCI breaker. The pigtail from the GFCI breaker to the neutral bus still needs to be connected though.

The function of the GFCI is not impaired by the lack of neutral if that's what you're asking.

I assume this question is a follow-on from the pier project, so a neutral would be used in that case because of the lights and other general-purpose loads on the multiwire circuit. Only the boatlift would not have a neutral connected as it is a straight 240V device.
