![]() This can be tricky, as the wiring is more complex than that of a standard plug. You may encounter a situation in which you have to wire a 4-prong 220V plug with just three wires. How To Wire A 4 Prong 220V Plug With 3 Wires? The DWC also eliminates all of the possibilities for incorrect wiring that come with pigtail wiring. All three of these are connected to the plug in one step. The DWC consists of two insulated wires and a bare ground wire. Using a DWC eliminates much of the work associated with wiring a 4-prong 220V plug with 3 wires. This is typically done by stripping the insulation off of each end of the wire and connecting them to their respective terminals on the plug. The traditional pigtail wiring method involves attaching four separate wires to both sides of the 220V plug: two hot wires, a ground wire, and a neutral wire. The first way is using the traditional pigtail wiring method and the second way is using a Direct Wire Cable (DWC). Wiring a 4-prong 220V plug with 3 wires can be done in two ways. Lastly, the green wire of the cord should be connected to the green screw on the plug. The white wire should be connected to the silver colored terminal screw. ![]() The black wire of the cord should be connected to the brass colored terminal screw on the plug. This can be done by using a voltage tester or by using the hot and neutral wires of the breaker box. When wiring a 4-prong 220V plug with three wires, the first step is to identify which wire is connected to which terminal. It is important to leave extra slack in case any adjustments must be made. You should make sure that there is at least 12” of usable wire on either side of the plug. Start by measuring the length of wire that you need to connect to the plug. You should also gather the necessary safety equipment such as safety glasses, insulated gloves, and a voltage tester. You will need a 3-prong plug, two 6 AWG insulated copper wire with strain reliefs, an appropriate size junction box, 2 – 3/8” machine screws and lock washers. Hydrocarbon grease adds a layer of fire hazard in an overheated connection and/or if it builds up in the receptacle over time.Before you begin, make sure that you have all the necessary tools and supplies at hand. Besides, your control circuits likely use the 110 in a DV machine.Īlso, greasing the lugs on the plug is a good idea, but use an electric-rated substance, like N0-Ox-Ide A or something similar (and a little dab'll do ya). You can use either for the center tap of the three-prong, as they'll be the same size wire all the way back to the breaker. The common and the ground are at the same potential, as they are bonded together at the main panel. (maybe that's for the Bluetooth circuit ) It's the common so your dryer can get 110 volts for its controler or whatever. I wanted to stick a screwdriver in thereĪlso.don't use that bottom prong. (nothing gets warm)Īlso if anyone uses an extension for the standard 220 plug, just grease the thing. I know it's Frankenwiring but it works fine. Got the right plug and just used that 110-220 adapter we got with the Everlast. Nelson wrote:I got a 12 GA short ext cord and cut off the female end.
