GFCI breaker sizing for 230V pump

[chrisexv6]

Looking at a MaxFlo XL 2 speed pump to replace my aging Northstar. Currently have 115V at the pump but the wiring is there to convert to 230V. Obviously Ill need a new breaker, and since its 230V I dont think there is any other way to get GFCI protection on the line other than the breaker itself.

I have a Cutler Hammer type CH panel. I notice the smallest GFCI breaker they make is 20A, yet Hayward electrical specs say the pump will use a max of 6.1A@230V.

Is 20A acceptable? And judging by the price and availability, would 30A suffice as well? I cant find the 20A version but the 30A seems widely available.

Thanks in advance.

The breaker is only there to protect the wire. The rating of the wire is the size breaker you need.

^^^^^
You size the breaker based on the wire size. What size is the wire?

Gotcha.

12AWG, so 20A max. They make a 15A GFCI breaker too, apparently, so Ill get whichever I can find.

Problem solved.

Thanks everyone.
