Pull Out 220 Volt Switch Wiring Diagram

Green earth ground is bonded throughout at the enclosures and the motor.

Pull out 220 volt switch wiring diagram. 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. The disconnect switch should be a 220 volt 2 pole type for both circuit wires. With both conductors carrying 120 volts there is an increased risk of injury or property damage. This switch doesn t use a neutral conductor.

Switch wiring shows the power source power in starts at the switch box. Depending on whether you have a 110v or 220v circuit you will have either 3 or 4 wires. Look for the grounding screw labeled green or ground directly across from the neutral screw. 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. 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. The national electrical code requires that all appliances over 300 volt amps or over 1 8 horsepower use some sort of means of disconnect. The black wire power out wiring attaches to the other switch screw.

Explanation of wiring diagram 1. For one thing both supply wires for this switch carry voltage. Wiring your disconnect switch will vary slightly from one type of switch to another. Circuit electrical wiring enters the switch box.

Fixture wiring exits the switch box. Put the green wire into the port next to the grounding screw and tighten it with a screwdriver so it doesn t move around or fall out.
