The switch isn't where you change the voltage. The configuration of connection in the wiring compart ment is where it's done. There should be a diagram on the motor showing the connections.

W
switching the voltage is shown in the diagram. It is connecting the power and switch that I need help with.
Electrician: Mike G., Master Electrician replied 1 month ago

The switch breaks 2 wires. Either a hot and a neutral for 120V or 2 hots for 240V. The switch connections aren't changed. In the wiring compartment you have 2 wires on each of the feed wires for 120V or only one each on the feed wires with the other 2 connected together.

To run 120 it says T1, T3, and T5 run to switch with T2, T4 and T8 run to switch. My power cord has black, white & green while the switch has red, white, black & green. What colors attach to what.

Connect as follows

L1=T1

L2=T4,T5

T,2,T3,T8 together

Swap T5 & T8 to reverse rotation.

The configuration you are using is for 230 volts.....maybe? See my 12:28 pm posting
Electrician: Mike G., Master Electrician replied 1 month ago

OK. You have 2 wires feeding the switch. They can be either 120 or 240V. Test the switch and use the 2 poles.

Electrician: Mike G., Master Electrician replied 1 month ago

Stop, I misread your question. I gave wiring for 240V. Stand by for correction.

Electrician: Mike G., Master Electrician replied 1 month ago

L1= T1,T3,T8

L2= T2,T4,T5

Is this correct......L1 to switch Black, L2 to switch White, switch green to ground. Where does switch red go?
Power cord black to ? , power cord white to ? and power cord green to ground.
Electrician: Mike G., Master Electrician replied 1 month ago

L1 is black, L2 is white, on the cord On the other end of the switch the motor wires connect as given. The green connects to the motor housing.

Ask Your Own Electrical Question
Customer reply replied 1 month ago
Are you saying Power cord black connects with switch black and L1.
Power cord white connects with switch white and L2.
What is the red wire on the switch connected to?
Electrician: Mike G., Master Electrician replied 1 month ago

The red isn't used. Only 2 are used black and white. Actually only one L1 is necessary to break the hot wire. The white neutral doesn't need to be switched but it can be.

Ask Your Own Electrical Question
Customer reply replied 1 month ago
If the power cord black, the switch black and L1 are wired together what breaks the hot
Electrician: Mike G., Master Electrician replied 1 month ago

There are 2 terminations on a switch pole.L1 has an in and out as do the others.

Connection of the cord black on one side and T1 on the other is what breaks the hot.
