I am taking this question to mean that you are making an installation using two wire cable that has a black and white in it. In this situation the white is not called a neutral. At the distribution panel end the white wire does not connect to the neutral bar. It will go to one side of a two pole breaker. the other side of the breaker will connect to the black wire of the cable. On the 230 volt receptacle end the two wires will connect to either side of the receptacle. Make sure that the cable wiring is rated to take the amperage that your plug-in device will draw. The last thing to do is identify the white wire as a "hot" current carrying conductor. This is done by placing black tape around the white wire. This is done at both ends of the cables white wire. This is done to ensure in the future that is someone else works on the circuit they will know that the wire is not a neutral conductor.In the market place there is a new cable that has no white wire in it. This cable is used for wiring baseboard heaters and has a different colour jacket to identify the type of cable it is. The internal wiring colours are black and red. This wire is used for all 230 volt circuits.

Where do you connect the white wire from the shunt breaker?

Connect to the circuit neutral wire which should also be white.


How do you put on a four prong outlet on a roper electric dryer?

Black & Red are hot, and White is neutral. If it has no place to connect neutral connect neutral to ground.


How do you wire two outlets in one box?

To wire two outlets in one box, you will need to connect the incoming power supply wires to both outlets. Connect the black (hot) wire to the brass screws on each outlet, the white (neutral) wire to the silver screws, and the green or bare wire to the green screw for grounding. Make sure to follow proper safety precautions and consult a professional if needed.


Why do white wire mark 120v?

Because the white wire on a 120 volt circuit is the neutral wire that is connected to the silver screw on outlets and switches. It is connected to the neutral bar in the service panel.


How to wire multiple outlets on the same circuit?

To wire multiple outlets on the same circuit, you will need to connect the outlets in parallel. This means connecting the hot wire (black), neutral wire (white), and ground wire (green or bare copper) from the circuit to each outlet. Make sure to follow proper wiring techniques and consult a professional electrician if needed.


Which side of the White neutral wire do you connect the Black power wire?

The neutral wire and power wire are never connected together.


Why do outlets have two prongs?

Actually they have 3. A round ground, wide neutral, and narrow hot. If it only has 2 it is an old outlet with no ground wire. If that is the case in your home, I highly suggest you connect a jumper wire from the ground screw to the white neutral wire on the silver screw to provide some protection. Do this at every outlet in the home. Replace all the outlets in your home with new ones if they are so old they do not have a ground connection.


How can I install electrical outlets in series?

To install electrical outlets in series, you will need to connect the wires from one outlet to the next in a daisy-chain fashion. Start by turning off the power to the circuit, then connect the black (hot) wires, white (neutral) wires, and green or bare (ground) wires from one outlet to the next. Make sure to use proper wire connectors and secure all connections tightly. Test the outlets before use to ensure they are working properly and safely.


How do you properly wire two outlets in one box?

To properly wire two outlets in one box, you will need to connect the incoming power source to both outlets using pigtail wires. Connect the black wires to the brass screws, the white wires to the silver screws, and the ground wires to the green screw or grounding screw. Make sure to follow the proper wiring diagram and use wire nuts to secure the connections.


Can you connect a green neutral wire to a white neutral wire?

In theory this should only ocure at the main junction box ... but if EVERYTHING is done right, then it is safe - but not in code.


How and where do you connect the white wire from the shunt breake to the electrical panel?

The white wire would go to the neutral bar. Just be sure of the shunt trip voltage required for the breaker and land the white wire on the appropriate neutral bar in the correct panel.


What is the correct wiring diagram for connecting multiple outlets in a circuit?

To correctly wire multiple outlets in a circuit, you should connect the incoming power source to the first outlet, then use a series connection to link the remaining outlets. Make sure to follow the proper color-coding for the wires (typically black for hot, white for neutral, and green or bare for ground) and use appropriate wire connectors to secure the connections. It is recommended to consult a professional electrician or refer to a reliable wiring guide for detailed instructions.
