Quick answer is that 220v does not use or need a neutral. The original concept of the neutral (going back to Edison and DC power) was cutting the power in half (not really accurate but one way to look at it). Think about two 110v batteries in series the neutral would come off the connection between the two batteries. so current flow would go from +110 to -110 (first battery) to +110 to -110 (second battery) resulting in 220 output. The connection between the batteries (the neutral) is +110 / -110 resulting in 0. If you want a 110 current instead of using the full flow you could instead use only 'one side' and the neutral and get the 110. When we made the move from DC to AC the basics of this format was kept. So for 110v you need hot and neutral (and a ground) for 220v you need two hots (no neutral) and a ground.
HUGE CATCH - WARNING - WARNING!!!
Just because you think your equipment is 220v doesn't mean everything it does it does requires 220v for example: some equipment uses 220v for the motor and 110v for the rest of its electrical needs (Dryers are a typical example). In the old days, the dryer would use the two hots (and ground for safety) for 220v and then use one hot and ground (no 'safety' ground) for 110v. However, people often got shocked because this unsafe method would often cause the entire metal chassis to take on a charge. So todays dryers (and any other machine that has both 220v and 110v components) have and are required to have 2 hots ground and neutral. However, the documentation isn't always specific about the '110v need' and a lot of 220v only equipment will still have 4 wire connections even though the neutral is not needed.
If you are sure your equipment never utilizes 110v - then you don't need a neutral (a single motor, no thrills (control panel, laser guides, etc), 220v table saw would be fine with out a neutral (one with the thrills may be fine also - depends on the power requirement of the 'thrills'). I don't know about your generator is depends if it is strictly 220v.

How would you make a patch cord to go from a 220V 30-amp 4-wire generator to run a 220V 20-amp 3-wire portable compressor?
To make a patch cord for this setup, you will need a 4-prong 220V plug that matches the generator's outlet, a length of appropriate wire rated for 30 amps, properly sized for the distance between the generator and compressor, and a 3-prong 220V plug that matches the compressor's inlet. Connect the wires according to color-coded standards (red and black to the hot terminals, white to the neutral terminal, green to the ground terminal). Make sure the wire gauge matches the amperage rating to avoid overheating.
Converting a pump motor from 110 to 220v 2 hot leads and a ground is there any use for the neutral?
No, the neutral wire is not needed for a 220V setup as it is a single-phase system. The two hot leads will supply the necessary power for the motor, while the ground wire is for safety grounding purposes. Always refer to the motor's specifications and local electrical codes when making such conversions.
When does a motor not need a neutral wire?
If the motor is operated from a three phase three wire distribution system the motor will not need a neutral wire.
How many wires does a straight 220V circuit have?
A straight 220V circuit typically has 2 wires - one hot wire (typically black or red) and one neutral wire (typically white). These wires are used to carry the electrical current to and from the device being powered.
How many conductors in 220v 30amp circuit using?
A 220V 30A circuit typically requires three conductors: two hot wires and one ground wire. An additional neutral wire may be needed depending on the specific electrical configuration or equipment being used.
What is the diagram for converting a 4-wire 220V connection to a 3-wire 220V connection?
To convert a 4-wire 220V connection to a 3-wire 220V connection, you will need to remove the neutral wire and connect the ground wire to the neutral terminal. This diagram shows the proper wiring configuration for this conversion.
How would you make a patch cord to go from a 220V 30-amp 4-wire generator to run a 220V 20-amp 3-wire portable compressor?
To make a patch cord for this setup, you will need a 4-prong 220V plug that matches the generator's outlet, a length of appropriate wire rated for 30 amps, properly sized for the distance between the generator and compressor, and a 3-prong 220V plug that matches the compressor's inlet. Connect the wires according to color-coded standards (red and black to the hot terminals, white to the neutral terminal, green to the ground terminal). Make sure the wire gauge matches the amperage rating to avoid overheating.
Is the neutral wire on a 220v outlet the same as the ground?
No it is not
How do you wire a 220v three prong to a 220v four prong?
You'll need to contact an electrician who will pull a new wire for you. If you only have 2 wires on the 240 line, you don't have a neutral or a ground; both of which are essential for a modern electric range.
Electric range 220 or 110?
Electrical range is usually 220V and requires at least a 40A breaker. In a three wire configuration, the white power carries 110V, the black wire carries 220V and the green wire is the ground. A four wire configuration has an additional wire that is neutral.
How can I convert a 3 wire 220V electrical outlet to a 110V outlet?
To convert a 3-wire 220V electrical outlet to a 110V outlet, you will need to rewire the outlet and change the circuit breaker. This involves connecting the neutral wire to the ground wire and replacing the outlet with a 110V outlet. It is recommended to hire a licensed electrician to ensure the conversion is done safely and correctly.
How do you wire a 220v dryer outlet correctly?
To wire a 220v dryer outlet correctly, you need to connect the red and black wires to the hot terminals, the white wire to the neutral terminal, and the green or bare wire to the ground terminal. It's important to follow the specific instructions provided in the outlet's manual and to turn off the power before starting the wiring process.
Converting a pump motor from 110 to 220v 2 hot leads and a ground is there any use for the neutral?
No, the neutral wire is not needed for a 220V setup as it is a single-phase system. The two hot leads will supply the necessary power for the motor, while the ground wire is for safety grounding purposes. Always refer to the motor's specifications and local electrical codes when making such conversions.
How do you wire 240V straight blade outlet when both screws are brass?
Both screws are brass because in the US you need two hots to get 220V. In a 220V only circuit you do not connect the neutral, only two hots and a ground. This is why 220V breakers are twice as wide as 110V and have two terminals instead of one.
How should I properly wire the generator plug for optimal performance?
To properly wire the generator plug for optimal performance, follow these steps: Make sure the generator is turned off and disconnected from any power source. Match the prongs on the plug to the corresponding terminals on the generator. Connect the ground wire to the grounding terminal. Connect the neutral wire to the neutral terminal. Connect the hot wire to the hot terminal. Secure all connections tightly. Test the generator to ensure it is functioning properly.
How do you wire 220V with 2 black 1 white wire?
Your black wires are your hot wires. The white is your neutral or common. It would be best to run an equipment ground (green wire) too.
When does a motor not need a neutral wire?
If the motor is operated from a three phase three wire distribution system the motor will not need a neutral wire.
