First off, this is bad practice and it doesn't meet code. Secondly, you don't have all the wires for a modern 120V connection. You have 3 wires coming into this circuit. Two are known to be hot. The third may be neutral or may be ground, depending on the outlet or wiring. If it is neutral (white wire) you can get 120V betwen this wire and either hot. Problem is you don't have ground. You can get away with a two prong plug and it may be fine, but you have to judge that depending on what you are powering. If the third wire is ground, sorry. Ground is a dedicated safety line and should carry current only in fault conditions. Don't use it as your neutral.
Also, if you do install this device, you need to take the overcurrent device into account. You want the weakest link in you chain of wiring devices to be the circuit breaker, and nothing else. So if you want to put a 15A outlet on a 50A circuit, you will need some sort of 15A overcurrent device in there. Either derate the circuit or add a breaker to your pigtail, if necessairy. (Also, if you derate you can drop the circuit to 120V and this whole discussion becomes moot.)

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

To wire a 120V outlet from a 240V 3-wire service, connect the black wire to one of the hot terminals on the outlet, the white wire to the neutral terminal, and cap off or tape the unused red wire in the 240V circuit. Be sure to use the correct amperage outlet and wire size for the 120V circuit. If you are unsure, consult a licensed electrician for guidance.
It is possible. For instance if you have a 30 amp 240 wiring to a appliance, you can tap a 120 out of it. You will need a small sub panel to do this. From there you will feed the the 120v and the 240v circuits. Check with your local codes to veriy.

Can you use a 120v cord that will fit a 240v socket the appliance is 240 and the cord is thick?
No, using a 120V cord in a 240V socket is not safe and can damage the appliance or create a fire hazard. The thickness of the cord does not affect the voltage compatibility. Make sure to use the correct voltage cord for the appliance to avoid any safety issues.
Can SJ 300V rated wire be used for 277v light?
No, SJ type wire is not rated for 277V application. This wire is typically designed for lower voltage applications such as 120V or 240V. It is important to use wire with the appropriate voltage rating to ensure safety and compliance with electrical codes and standards.
If you do not have a 240v outlet for a washer and dryer can you work around this or does an electrician have to come and install a new outlet?
If you do not have a 240v outlet for your washer and dryer, you will need an electrician to install a new outlet. It is not recommended to work around this by using an adapter or altering the existing outlet, as it can be unsafe and may not provide the necessary power for your appliances. It's best to have a professional electrician assess the situation and install the appropriate outlet for your washer and dryer.
Can you take a 240v 20a garage outlet number 12 with 4 wires and split it into two 120v circuits while still keeping the 240v outlet?
Yes, you can split a 240V outlet with 4 wires into two separate 120V circuits. You will need to install a double-pole breaker at the main panel to split the circuit. Ensure proper wiring and connections are made to maintain the 240V outlet and create two 120V circuits. It's recommended to consult with an electrician to ensure safety and compliance with electrical codes.
If you had a wall AC unit that ran on 240V and you got a new one that runs on 120V how do you change the wall receptacle outlet wiring to be able to run 120V instead of 240V and how about the breaker?
To change the wall receptacle for the new 120V unit, you will need to replace the existing 240V outlet with a standard 120V outlet. This involves disconnecting the old outlet, rewiring it for 120V, and installing the new outlet. As for the breaker, you will need to replace the 240V breaker with a 120V breaker to match the voltage requirements of the new AC unit. Installation should be done by a qualified electrician to ensure safety and compliance with electrical codes.
I have 240V 3 wire twistlock plug and want to wire it so I have 120V outlet?
Don't!
How do you upgrade from 120V 15A to 120V 20A or from 240V 20A to 240V 30A?
You have to replace the wire (as you are increasing the current capacity), the outlet, and the breaker. Essentially you have to remove the old circuit and put in a new one. You can't reuse parts of the old circuit as you are increasing the current capacity and they would be underrated.
How can you get 240V single-phase power from a 240V 3-phase service Can you just connect to two poles of the 240V 3-phase service?
If the 240V 3-phase service is 240V phase-to-phase, then you can get 240V single-phase by simply picking two phases (poles, as used in the question) and connecting the load across them. This is simply one third of a standard delta connection. If you need 120V/240V split phase, i.e. with a neutral, as used in residential services, you will need a transformer. If the service is actually a four wire "quadraplex" service, however, you will probably already have that 120V/240V with neutral connection phase available. In this case, you will need to pick the two phases correctly in order to get the proper 120V service half.
What is 2 wire plus ground 240V?
With one interpretation of this question, the answer would be two 120V wires and a ground.
How can you get 240V single phase power from a 240V 3 phase service Can you just connect to two poles of the 240V 3 phase service?
I'm sure this isn't what you want to hear, but you probably need to ask an electrician familiar with your service and what you want to connect. As a general answer, you can connect a 240v line to line resistive load like an electric water heater to any 240v source. If you also need the 240v to have 120v line to neutral, like a 240v electric stove that contains a 120v clock and oven light, then its possible if the 3 phase power is connected in a "high delta" configuration, and you connect to the correct leads. If you have a high delta service and want to ignore the 3-phase power service and wire most or all of the loads in the building as a single phase load, the utility may have to be consulted.
How do you upgrade the service from a 120V 100A circuit breaker to 240V 30A for appliances like ovens and dryers?
Have an electrician wire you a proper line for the appliance. You were just kidding about the 100A, right? 10, or 20amp, not 100.
Can you use a 120v cord that will fit a 240v socket the appliance is 240 and the cord is thick?
No, using a 120V cord in a 240V socket is not safe and can damage the appliance or create a fire hazard. The thickness of the cord does not affect the voltage compatibility. Make sure to use the correct voltage cord for the appliance to avoid any safety issues.
How can you wire a 110V plug outlet from a 240V plug outlet not speaking of a converter but actually changing the plug outlet so that there are no long term effects on the 120V appliance?
Assuming the wiring to the outlet has 2 loads and one neutral, isolate one load from the outlet and use the neutral as the common. be sure to ground from the receptacle to your conduit or ground lead. You should also replace the corresponding breaker with a 120 volt single breaker.
Can SJ 300V rated wire be used for 277v light?
No, SJ type wire is not rated for 277V application. This wire is typically designed for lower voltage applications such as 120V or 240V. It is important to use wire with the appropriate voltage rating to ensure safety and compliance with electrical codes and standards.
How do you wire 240V to 120V?
What specifically are you wiring? A light bulb would operate dim, a motor will burn up. The current increases thereby requiring larger wire and current protection.
How is the power supply in Europe delivered with two wires and still 220 volts?
Oh yes. They do provide 2-wire 220V and even 2-Wire 240V service in Europe. We went a different way in the States early on when we attached a center-tap wire in those same service transformers to provide 2 x 110V services, along with one 220V service. It is worthy to mention that 110V (220V) services in the US progressed to 115 (230V) and now stand at 120V (240V).
