You want the two breakers to straddle the divider
Better to buy a 'double' in the first place.
Just to throw my 0.02 cents in- you’ll have two hots, (likely red and black), a neutral (usually white) and a bare copper for a ground. It’ll be called 12-3 or 14-3 because nobody counts the ground
You need 12-3 or 14-3, for 240v. That’s the way I’ve always done it, and always seen it done anyway.I have 12-2 and 14-2? There are only 3 wires going into the FWD-STOP-REV switch.
For this motor you only need the two hot lines and ground. The neutral is not used. You therefore only need 14-2 plus the ground.
