Question: where do you connect the white neutral wire from the gfci double pole breaker if its a 220v circuit

Answer: Hi Jason,

The White wire on a 220 volt circuit can be a hot wire or a neutral. If there is a red wire the white wire is a neutral and there should be a lug marked with a white dot.

If there is not red wire the white wire is a hot wore and it goes under one of the hot lugs.

If you are not familiar with this equipment I think you should contact an electrician who is. I don't think working is your main panel is a place to learn things the hard way.
