I have a Speedaire 4B234 its currently wire to 120V but keep flipping the breaker and I have a 240V in the garage so I want to wire it to that. I have 2 blue wires, 2 red wire, and 2 green wires but the green wires are hooked together. One blue wire goes to Line and the other to Motor and same thing with the red wires.
You cant run 220 into a 110v motor. Buy a 20amp breaker and install it in your panel. Should take care of the problem.
I looked up the specs on the 4B234. Says it CAN be wired to 240. You will just have to follow the wiring diagram on the motor or with the instructions. Specs say it pulls 15 amps at 120 v or 7.5 amps at 240 v. Your problem now is that maybe you only have a 15 amp or a 20 amp breaker. 15 amps is probably the continuous running draw. The current surge on start up goes over 20 amps and is what is flipping your breaker. you will need a double pole (2 wire) 20 amp breaker. wire it with #12 wire. Say a green, red, black. (or you can use blue and red) Green is always ground (should be). 240 volts works by being 2-120's out of phase by 180 degrees. One wire is pushing (+) while the other is pulling (-). You hook one wire to the motor in and the other to motor out. Running 240 will increase your efficiency.
Go to any store that sells them and look at the manual. Better still, Google for the manual.
