Solderless bread boards are not a good idea for power over a 1/2 amp there to much that can go wrong with them. I would make a PCB or for one off things use a solder bread board with gang tracks and over size them.

Where I work I've fixed a lot of poorly made boards that controlled motors
The older boards always had solder covered tracks which helps to fix some poorly made boards.

The main problem is the resistance of the tracks which is much higher than actual copper wire, that will create heat as the current raises, heat will cause it to melt and perhaps short circuit producing some very nice sparks as the tracks probably blow apart(if ur power supply can handle it) all in a little cloud of black smoke, best way is to use some 18-22 gauge stranded wire soldered point to point, with the main feed wire being a little larger
