Wiring 220v


I am wiring a vacuum pump for a vacuum-form table to a 220v. 3 wires coming of the wall - black and red (I assumed are hot) and white (neutral). I also have a vacuum switch (installed between the pump and the tank) and a main switch (to turn the table on and off).

The pump wiring diagram has a L1 and L2 posts. I guessed that will take the 2 hot wires. So where should I connect the neutral wire.

Since I plan to wire the whole set up in a loop, I assumed the vacuum switch and the main switch will only take both of the hot wires. Is that correct?

Let me know if my description doesn't make sense.

Please help.

A pure 240-volt appliance needs no neutral. It sounds like you might be trying to convert a circuit wired for something else (such as a clothes dryer) to serve this vacuum. This is not always safe. Post back with more details about the circuit you are connecting this to. Also tell us the electrical specs of the appliance.
