Interestingly, you don’t have to replace a 3-prong outlet with a 4-prong outlet, especially if you live in an older home. You can also replace a 3-prong cord with a 4-prong cord if the receptacle has four slots. The objective of the procedure above is to replace a 4-prong cord with 3 wires. Although, it helps to remember where you connected each wire. The green wire goes to the ground screw, the white line to the neutral terminal, and the black and red wires to the hot terminals. Connect the new cord with its 4-prong plug.The neutral wire should run to the neutral terminal. This is where 3 and 4-wire systems differ. Remember that the neutral wire is connected to the ground screw.Disconnect the power cord’s wires from their terminals. Use the screwdriver to remove the screws.You can also look at the point where the power cord connects to the appliance.

The manual will show you where to find these connections. Find the electrical connections on the device and remove the metal plate protecting them.Disconnect the appliance from the power source.

That includes a screwdriver, socket wrench, and pliers.

How To Wire A 4 Prong 220V Plug With 3 Wires? You can buy items such as this AC WORKS 3-prong to 4-prong adapter that bridges 3-wire and 4-wire systems. Naturally, the cheapest option is the adapter. Therefore, the labor fees won’t change drastically. It takes relatively the same duration to replace a power cord. Don’t expect that figure to fall if you take the other option.

The cost doesn’t matter as much because you will spend $25 or less regardless of whether you need a new power cord or an outlet.Īnd if you hire a technician, Angi expects you to spend anywhere between $135 and $307 to install a 220V outlet. Most appliances are safe enough once you unplug them. You could kill yourself by forgetting to de-energize the circuit. An outlet is connected to a 120/240V circuit. Power cords are easier to replace for laypeople. What you choose to do will depend on your skill level. Again, you can do the reverse (getting a 3-prong outlet to match a 3-prong plug). Get a 4-prong receptacle that matches the 4-prong plug. You can also do the reverse, that is to say, replacing a 3-prong cable with a 4-prong cable. But they are more likely to get confused because the power cord has four wires, but the 3-prong plug only requires three lines. Some laypeople prefer to replace the plug. You have three solutions at your disposal: What does this mean? A 4-prong plug won’t fit a 3-prong outlet. Many homes built before that year have 3-prong outlets.īut if you just bought a modern heavy-duty appliance, such as a clothing dryer, it may come with a 4-prong plug. 4-prong plugs and outlets became mandatory in 1996. People will only use a 3-wire system with a 4-prong 220V plug because they live in an older home constructed before 1996. What Are Some Common Reasons Why A 3-Wire System May Be Used With A 4-Prong 220V Plug?

Connecting the neutral to the metal frame in this setup violates the NEC’s rules.

The grounding conductor is the only wire that provides a path for the current when a fault occurs.

The grounding conductor connects to the metal frame instead of the neutral wire.

You have four wires instead of three: two hot wires, a neutral and a ground wire.

They have an advantage you don’t see in 3-wire systems: This is why the NEC mandates the use of 4-wire cords and receptacles.

A broken ground condition can energize the metal case. Keep in mind that the absence of a ground wire compels you to run the neutral line to the metal housing’s ground connection.

It was also common practice to run the neutral line to the appliance’s metal housing.

The neutral line provides a return path for the current.

You need both hot wires to provide the 240 volts heavy-duty devices use.

The hot lines are 180 degrees out of phase from each other.You have three wires: two live conductors and one neutral.After all, they were in use for decades before 4-prong plugs and receptacles became mandatory.
