Simple Wiring Problem

I am installing a new irrigation pump. The pump can be changed from a 115 to a 230 volt simply by moving a clip from one to the other. This is a direct wire hook-up with a black, white, and blue wire going from the panel box to the motor. The panel box has 2 20 amp breakers connected together (on top of each other with the little silver bar connecting them together). My questions are, (1) based on the amps in the breaker box, do I need to make a 115 or 230 volt connection and (2) with a blue, a white, and a black wire - which 2 need to go to L1 and L2 on the motor, and which one is the ground?

You have nor provided enough information.

What does the pump say it needs in terms of current at each voltage? You need to understand what the pump needs, then decide what you want to provide it.

As for the connections, contact the manufacturer. Blue, black and white implies the ground is connected elsewhere. Consult the manual.

#1) Please provide all of the information from the metal nameplate on the pump. You have described a double-pole breaker which indicates the existing wiring is for a 230V pump. This is the prefered installation.

#2) None of them is. A ground may only be colored green or be bare. It sounds like your existing wiring may not be up to code for re-use. Are these wires installed in a metal conduit? If so it can be legal to use the metal conduit as a ground. Please describe the situation more precisely.
