Yes but it is not compliant with the NEC you can use a 240 volt circuit, (Ground, Hot, Hot) you would use a (either) hot wire with a ground wire and that will be a 120 volt circuit.
I strongly advise you not to do this though because a ground wire is not trully meant to carry current and it will not be approved by any inspector.

What is the need for neutral wires in circuits for electrical services?
The neutral provides a path back to the source for the electricity. In a three-phase circuit, it is mainly used to carry the unbalanced load back to the source. In theory, a perfectly-balanced three-phase circuit would not need a neutral, but this is almost impossible to achieve in actual practice.
Can you use 3 phase circuit as 3 separate single phase circuit?
Yes, a 3-phase circuit can be used as three separate single-phase circuits by connecting each load to one of the phase conductors. This allows you to operate three independent single-phase loads using the same 3-phase power source. However, caution should be taken to ensure that the loads are balanced among the phases to avoid overloading any of the phases.
What is a dedicated neutral wire?
A dedicated neutral wire is a separate conductor in an electrical circuit that provides a return path for current to flow back to the electrical panel. It is used in residential and commercial wiring to prevent shared neutral issues and ensure proper functioning of the circuit.
Can two circuit share the same common and ground wires?
US NEC: The only place two circuits can share the same neutral (common) and ground wires is at the distribution panel, and that is only because those two conductors are tied together at the distribution panel.
Why do you convert 120v circuits to 220v circuits?
You would need to change a circuits voltage if your adding a load that requires 220 when the present circuit supplies 120. If you need to do so it's pretty simple! First purchase a double pole breaker at the proper amp rating. Next find the breaker in the panel that supplies power to the circuit you wish to change to 220. Turn off the breaker and pull it out. Find the neutral for that circuit. Then double check and make sure it's the right neutral. Then check one more time. Now take the neutral and the hot wire for that circuit and connect them to the double pole breaker. install the breaker into the panel and turn it on. If you connected the right neutral you'll have 220 on that circuit. If you didn't you'll know because you'll trip the breaker.
Can you use a GFCI on an unswitched circuit line red that uses the same neutral white for a switched circuit coming from the other phase line black in a 240v breaker panel?
Yes. You are allowed to use a neutral for one circuit from each phase of your service. For example, in a residential service, you can use the same neutral for circuits 1 and 3. In a commercial (3 phase) service, you can use a neutral for circuits 1, 3, and 5. You will experience problems if you use a neutral for two 'black' circuits or two 'red' circuits, if the circuits originate from the same phase bus bar. Also, AFCI's are sensitive to sharing neutrals, but GFCI's are not.
What is a double pole breaker and how does it differ from a single pole breaker in terms of electrical circuit protection?
A double pole breaker is a type of circuit breaker that controls two separate electrical circuits at the same time. It differs from a single pole breaker in that it can disconnect both the hot and neutral wires in a circuit, providing greater protection against overloads and short circuits. This makes it suitable for larger appliances or circuits that require more power.
What is the function of a double pole contactor in an electrical circuit?
A double pole contactor in an electrical circuit is used to control the flow of electricity to two separate circuits simultaneously. It allows for the isolation and switching of both the live and neutral wires in each circuit, providing a higher level of safety and control in the electrical system.
What is the common wire in electrical circuits and how is it used in wiring systems?
The common wire in electrical circuits is also known as the neutral wire. It completes the circuit and provides a return path for the current to flow back to the power source. In wiring systems, the neutral wire is connected to the neutral bus bar in the electrical panel and is used to balance the electrical load in the circuit.
What is the need for neutral wires in circuits for electrical services?
The neutral provides a path back to the source for the electricity. In a three-phase circuit, it is mainly used to carry the unbalanced load back to the source. In theory, a perfectly-balanced three-phase circuit would not need a neutral, but this is almost impossible to achieve in actual practice.
What is the difference between a ground bar and a neutral bar in an electrical panel?
A ground bar is used to connect the grounding wires of electrical circuits to the panel's grounding system, while a neutral bar is used to connect the neutral wires of electrical circuits to the panel. The ground bar is for safety, while the neutral bar is for completing the circuit.
Can you use 3 phase circuit as 3 separate single phase circuit?
Yes, a 3-phase circuit can be used as three separate single-phase circuits by connecting each load to one of the phase conductors. This allows you to operate three independent single-phase loads using the same 3-phase power source. However, caution should be taken to ensure that the loads are balanced among the phases to avoid overloading any of the phases.
What is the neutral wire used for in electrical circuits?
The neutral wire in electrical circuits is used to complete the circuit and provide a return path for the current to flow back to the power source. It carries the current back to the electrical panel to ensure a balanced flow of electricity and to prevent electrical hazards.
What is a dedicated neutral wire?
A dedicated neutral wire is a separate conductor in an electrical circuit that provides a return path for current to flow back to the electrical panel. It is used in residential and commercial wiring to prevent shared neutral issues and ensure proper functioning of the circuit.
What is a plug on neutral and how does it differ from traditional electrical wiring systems?
A plug on neutral is an electrical wiring system where the electrical outlets have a neutral connection built into them, eliminating the need for a separate neutral wire in the electrical circuit. This differs from traditional electrical wiring systems where each outlet requires a separate neutral wire connection.
Can two circuit share the same common and ground wires?
US NEC: The only place two circuits can share the same neutral (common) and ground wires is at the distribution panel, and that is only because those two conductors are tied together at the distribution panel.
Why neutral is not required for vacuum circuit breaker?
Air-blast circuit breakers are used to disconnect high-voltage transmission or distribution circuits in the event of a fault. One circuit breaker is required for each of the three line conductors; there is not normally a neutral conductor in high-voltage three-phase transmission/distribution lines.
