The black wire power out wiring attaches to the other switch screw.

Pull out 220 volt switch wiring diagram. This switch doesn t use a neutral conductor. Explanation of wiring diagram 1. The black wire power in source attaches to one of the switch screw terminals. Pull on the green wire to make sure it doesn t slip out from the outlet.

With both conductors carrying 120 volts there is an increased risk of injury or property damage. Look for the grounding screw labeled green or ground directly across from the neutral screw. Depending on whether you have a 110v or 220v circuit you will have either 3 or 4 wires. Circuit electrical wiring enters the switch box.

Wiring a 20 amp 240 volt switch can be a confusing experience for the average homeowner used to working with standard 110 volt circuits. The standard 220 volt wiring for an air compressor includes no polarity for the red and the black wire so you cannot wire them backwards. A pull out disconnect switch gives a technician a safe way to work on high voltage appliances without the need to access the appliance s circuit breaker. I will make sure to create a wiring diagram soon.

Green earth ground is bonded throughout at the enclosures and the motor. One will ground a bare copper or green wire one will be neutral a white wire and one or two will be hot wires black or a combination of black and red. The disconnect switch should be a 220 volt 2 pole type for both circuit wires. Fixture wiring exits the switch box.

The national electrical code requires that all appliances over 300 volt amps or over 1 8 horsepower use some sort of means of disconnect. Wiring your disconnect switch will vary slightly from one type of switch to another.
