How can I get ground fault protection on a 240 V circuit breaker?

Use an FAL breaker with a G suffix, and a GFM100FA for equipment ground fault protection at 20A. Or use an OEM Mounting Base with a QO220GFI for personnel protection or a QO220EPD for 30 mA equipment ground fault protection.
If UL listing is not required, they could use a Multi 9 breaker with a Vigi Module.
