Gfci breaker install

Hello all just a little help with a gfci breaker that i need to install on a swimming pool pump. I understand the installation procedure which says that you need to use the white or neutral wire from the same cable. The problem is that this cable has to black wires two white wires and one green, or ground wire. How can i tell which is the white wire that belongs to the line that i need? Thanks Any help will be appreciated.

You'll need to find the other end of the circuit to see what the extra set of wires powers.

If you disconnect a white wire (while leaving all black wires connected), the load that that white wire serves will quit working. So by disconnecting one white wire at a time, you can figure it out. Shut off the main breaker before touching any white wires.
