The only pumps I'm aware of that have blue or brown wires are made overseas somewhere. So if it's a Goulds, I'm not aware of what the unit looks like. Can you post a picture; so we can see where these wires are going?
I'm not sure what a four wire breaker is.I am using a 4 wire 20 amp double pole 20 amp breaker which it calls for.
As far as the colors on the four wire conductor your using, and electrician would be the guy to tell what colors to use for 230 volts. My guess would be black and white. Ground to green.
