Gathering Necessary Tools
Before you begin the wiring process for a 220V plug with three wires, you’ll need to gather all of the necessary tools and materials. These include wire cutters, screwdrivers, electrical tape, a voltage tester, an ohm meter, wire strippers (if needed), and of course the plug itself. Once you have all of these items ready, you’ll be ready to begin wiring your plug. 
Identifying the Wires
Identifying the wires to your 220v plug may seem like a daunting task. Fortunately, it’s not hard if you know what to look for! Start by locating the two black wires and one white wire. The two black wires will be connected to either end of the plug, while the white wire will be connected to a neutral slot in the middle. 
- Disconnect all power to the circuit by turning off the appropriate breaker in your home’s circuit breaker box.
- Remove the existing 220-volt receptacle from the electrical box, using a screwdriver to unscrew the mounting screws that hold it in place.
- Strip 3/4 inch of insulation from each wire connected to the existing 220-volt receptacle.
- Connect each of the three insulated wires – black, white and green from the circuit wiring to the correct terminals on a 3-wire 220 volt plug, using a screwdriver or other device. The green wire (ground) will be connected to the round terminal located at one end of the plug; the two remaining insulated wires – black and white – will be connected to the two brass terminals located at the opposite end of the plug.
- Install the 3-wire 220 volt plug into the electrical box, using a screwdriver to secure it in place with mounting screws.
- Turn on all breaker switches associated with this circuit and test your newly wired 3-wire 220-volt plug for proper operation. 
How To Wire A 220V Plug With 3 Wires?
If you’re looking for a way to connect your appliances and other devices that require 220V power, but don’t have the usual 4-wire plug, then wiring a 220V plug with 3 wires is your solution. It may seem like an intimidating task at first, but as long as you have the right tools and follow the instructions carefully, it is actually quite simple.
To start off, you’ll need to gather all the materials and tools that you will need:
- Power drill
- Wire cutter or pliers
- 220V male plug/outlet
- 3 wires
- Electrical tape
Once you have these items, make sure to turn off your power supply before commencing.
First, use the wire cutter to strip off the insulation from each wire to expose around 1-2 inches of bare metal. Then twist these exposed wires together, leaving enough room not for them to touch each other or any other metal objects in the area. Once your wiring is done, you can tape it up with electrical tape for extra security.
Next, take the 220V male plug and loosen its terminals. Insert each of your three wired ends into the respective slots on the plug, making sure that you are placing them in the right position according to their label (hot/neutral/ground). Once they’re tightly secured, you can screw back on the terminal screws to completely secure them in place.
Finally, use your power drill to secure the plug into a wall outlet. Make sure that you are drilling the holes in an appropriate area and with enough depth so that it can fit snugly into the outlet.
Running the Wires
Once you have the outlet box securely mounted, it is time to run the wires and make the electrical connections. To begin, turn off the circuit breaker that supplies power to the outlet before starting any work.
In most cases, a 3-wire cable will be installed inside an outside wall to provide power from a nearby 220V breaker panel. The cable should be colored black, red and white. The wire ends must be stripped of insulation before you can attach them to the outlet terminals.
The two black wires from the cable will attach to the brass-colored terminals on the outlet. To ensure a secure connection, twist each firmly onto its respective terminal and tighten down the screws with a screwdriver. Make sure that the blacks are connected to the brass terminals and not the silver.
The red wire will attach to the silver-colored terminal and should be treated in a similar manner as the black wires. Finally, you can attach the white neutral wire to the green ground terminal located at one end of the outlet platform. 
Attaching the Wires to the Outlet
Now that you have all the materials, it is time to begin wiring your 220V plug with three wires. Start by attaching the ground wire (green or bare copper) to the outlet. Take the end of the wire and secure it into place using a connector screw. You may need to use pliers to get the connector screw tight enough.
Once that is done, you can start attaching the hot wires (black and red). Again, make sure to use a connector screw to secure them in place. If there are any extra wires that are not needed for this project, be sure to tuck them behind the outlet and out of sight.
Now it is time to attach all three leads together. Take all three of the wires and connect them to a terminal block such as a wire nut. Make sure that all three leads are securely fastened and wrapped in electrical tape for extra protection. 
Connecting the Breakers to Power
The last step in wiring a 220V plug with three wires is to connect the breakers to power the outlet. The breakers should be mounted on the main electrical panel, and they will need to be wired to the appropriate outlets in order for them to provide power. When connecting the breakers, it is important that you make sure they are properly labeled and that they are connected in the correct order.
Once the breakers have been wired, you will need to make sure that all of the wires are connected correctly and securely. Make sure the wire is tight so there is no danger of it becoming loose and causing a short circuit. 
Use a dryer plug adapter
If you’re looking for an easy way to wire a 220-volt plug with 3 wires, then one of the simplest solutions is to use a dryer plug adapter. This type of adapter can be found in most hardware stores and it allows you to easily convert a standard three-prong plug into a four-prong dryer socket. The directions on the package are simple and easy to follow, so you should be able to wire the plug in no time.
Once you’ve got the adapter, you can then connect the three wires from your 220-volt appliance or device directly into the dryer plug. The two black wires get connected to the two outer connectors on the dryer socket and then your red wire is connected to the center connector. Make sure that you connect the wires securely and tightly so that there is no chance of any loose connections. 
What Are Some Common Reasons Why A 3-Wire System May Be Used With A 220V Plug?
Replace the power cord
When a 220V appliance is plugged into a 3-wire system, it means that the appliance has two phases of power instead of just one. This type of arrangement is necessary for some appliances such as clothes dryers, water heaters, air conditioners and ovens. Sometimes a 3-wire system can be used to replace an existing 2-wire system. This is typically done when the old power cord is worn out or damaged and needs to be replaced. 
Replace the outlet.
Another reason a 3-wire system may be used is to replace an existing 2-wire outlet. This can usually be done without replacing the entire wiring system, but will require an electrician to ensure that the job is done correctly and safely. The electrician will need to install the proper size wiring for the appliance and connect all of the wires to the correct terminals. 
Get an adapter.
In some cases, a 3-wire system may be needed in order to use an appliance on a 2-wire system. In this case, an adapter will need to be installed in order to convert the 2-wire outlet into a 3-wire outlet. This should also be done by an experienced electrician and can sometimes be difficult due to the complexity of wiring.
Differences Between 3 Wire And 4 Wire Systems
Before we get into discussing how to wire a 220V plug with 3 wires, it is important to note the differences between 3 wire and 4 wire systems. A 3-wire system consists of two hot wires (black and red) that are each connected to a voltage supply, as well as one neutral wire (white) which connects to the ground. In contrast, a 4-wire system has an additional ground wire (green or bare copper).
The main difference between the two systems is that in a 3-wire system, the voltage supply is directly connected to the appliance. This means that if there is any fault in either the wiring or the appliance itself, it may cause a dangerous shock to anyone who touches it. For this reason, it is important to ensure that the wiring is installed correctly and all safety precautions are taken.
In contrast, a 4-wire system has an additional ground wire which serves as a safety measure in case of any fault. This ground wire grounds the appliance, preventing electricity from flowing through it and causing injury or damage.
