Hook up 220 volt breaker

The green wire, or bare copper wire, is the ground, which is there for electrical safety. Instead there is an additional hot wire which is usually red or blue in color. The two hot wires complete the circuit.

This wiring must be connected to a two-pole breaker at the circuit panel to account for the two leads. In essence, a two-pole breaker is 2 single-pole breakers that have been wired together. This type of volt wiring is most commonly used for providing power to electric water heaters, boilers, or condensing units. These appliances do not require volt power. Another type of volt wiring is used to power appliances such as stoves and dryers. These devices require volts to power their main function but use volts to power accessory equipment such as clocks and timers. In addition to the two hot wires, this type also contains a white neutral wire to complete the circuit for the accessories that require a volt circuit.

  • As with any type of electrical wiring, a bare copper wire or green wire is also used as the ground wire. Similar to 3-wire volt wiring, the use of 4-wire volt wiring will require the installation of a two-pole breaker in the circuit panel. The wires for a volt outlet are too stiff to allow you to simply stuff any extra into the wall. Strip off about 2 inches 5 cm of the insulating jacket on the wires. Use a utility knife. Be careful not to cut the inner insulation. Use wire strippers to do this.


    Connect the wires to the outlet. Study the outlet and connect the wires to the terminals either by pushing them into the terminals or bending them around a screw and tightening the screw. Four-conductor outlets have 3 terminals corresponding to the vertical slots on the left, right and top-center, and a terminal corresponding to the rounded bottom slot. The black wire is "hot" and connects to one of the terminals on the left or right.

    It makes no difference which side you connect the black wire to. The red wire is also "hot" and connects to the other left or right terminal. In 3-conductor connections, there is no red wire. The white wire is neutral and connects to the top terminal. The bare wire is ground and connects to the terminal corresponding to the bottom, rounded slot. Test your connections to make sure they're correct. Turn on the breaker and use a voltmeter or multimeter. The voltage between the left and right terminals should be The voltage between the left or right terminal and the neutral terminal should be The voltage between the neutral and ground terminal should be 0.

    Turn off the breaker, assemble the outlet and install it in the wall. Did you mean Not Helpful 3 Helpful Use a wire nut to cover the neutral and tape it securely. Just connect the hot terminal and ground. Not Helpful 16 Helpful I wired a table saw with the v plug. I changed from a range receptacle to a twist lock receptacle. There was no green wire, so I put the red wire where the green should have been. Green is for ground, red is hot. You probably don't have v anymore.

    How to Connect a 220-Volt Receptacle to a 20-Amp Breaker

    Not Helpful 9 Helpful Technically you can, but you shouldn't. No building code that I know of allows this. Electric water heaters and dryers should always be on their own dedicated circuit. At the very least, you would be tripping breakers or blowing fuses constantly. In the worst case scenario, you could electrocute someone or burn your house down.

    If you have ever seen a panel, you would see that there are breakers on both sides of the panel. Each side is volts, and both sides together are volts.

    It's called single phase is because you can only have one phase variance between the two wires. Not Helpful 11 Helpful Not Helpful 3 Helpful 5. I have a outlet that has 10 wires for the neutral ground and one hot leg. The other hot leg is a 8 wire.

    Is this a problem? It's sloppy, and indicates the installer was not paying attention, or made a slip up in wiring and didn't catch it or didn't fix it. It also implies that the wiring was not properly inspected. Whether this problem could lead to a fire depends on the amperage of the circuit breaker, and the length of the wires from the breaker to the receptacle. Not Helpful 2 Helpful 2.

    Understanding 220 and 230 Volt Wiring

    Can I switch a single breaker with a double safely if I need more outlets? The short answer is yes. However, if you are wiring according to the current national electric code, then you may be required to use arc-fault-circuit-interrupter breakers. I have found these hard to find for double breakers, perhaps because they are not manufactured yet.
