Pull Out 220 Volt Switch Wiring Diagram
The disconnect switch should be a 220 volt 2 pole type for both circuit wires.
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. Pull on the green wire to make sure it doesn t slip out from the outlet. Wiring a 20 amp 240 volt switch can be a confusing experience for the average homeowner used to working with standard 110 volt circuits. Circuit electrical wiring enters the switch box.
Green earth ground is bonded throughout at the enclosures and the motor. This switch doesn t use a neutral conductor. 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. 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. 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. Fixture wiring exits the switch box. Switch wiring shows the power source power in starts at the switch box.
For one thing both supply wires for this switch carry voltage. Depending on whether you have a 110v or 220v circuit you will have either 3 or 4 wires. With both conductors carrying 120 volts there is an increased risk of injury or property damage. I will make sure to create a wiring diagram soon.
Wiring your disconnect switch will vary slightly from one type of switch to another. Explanation of wiring diagram 1.
