With our ultimate guide to 120v to 240 Converters, you'll find everything you need to power up in no time at all. Question: I’m hooking up an air compressor in my shop. It is a dual voltage, 8A/240V, or 16A/120V. I have a 15A 120V single receptacle on a dedicated circuit that used to run my old compressor. It used to only draw 7A on 120V, and it was not a dual voltage motor. Do I have to run a new circuit to the compressor? It is about 40ft. from the panel, and the walls are all finished with plywood and insulated. Start by looking at the air conditioner. You need to know the number of "watts" the air conditioner uses, probably between 1000 and 3000. This number is often called VA instead.
While most consumer goods, including portable electronics and most appliances, run on 120V power, some demanding more power rely on 240-volt electrical systems. The following are the most commonly used appliance requiring 240V power: Next, you'll need a 240-120V step-up/down transformer whose watts (or VA) rating is larger than the air conditioner. You set the transformer for 120V input, plug it into the generator, and plug the 240V A/C unit into the 240V receptacle on the transformer. Turn off the outlet power at the main breaker. Use a voltage line tester to make sure there is no power running. Reference: University of Florida, Electrical systems differ, IEC World Plugs,ResearchGate, Electrical Injuries. If you have local codes that differ from the NEC codes, prioritize the local codes. Why is it important to have 240V outlets?Always turn off the power to work on your house’s electrical system. How to wire a 240V electrical outlet?
volts" and "220 volts" represent an older standard for electrical wiring in the United States and Canada. However, in many regions, voltages have gradually increased from 110V to the current standard of 120/240V at 60 Hz. The term and use of 110V and 220V are still common. You must perform this step carefully to transfer the 120V outlet to 240V properly. Step 4: Install the 240V outlet Though most US countries lead their life with 120V outlets, sometimes 240V outlets are needed for some specific appliances that need higher voltages for power transmission. Other than these, some other larger appliances use more energy than the average level and, thus, need high-voltage outlets.Sometimes, the electrician might have to rip open the walls. In that case, you will have to pay thousands of dollars. That brings us to the end of our ultimate guide to 110V to 220V Converters. We want this to be an evolving resource.

We'll update this post with your question and our answer, powering up this post and the knowledge of future readers.
Series-wound brush motors don't care what frequency the power line runs at, because the timing of the brushes and commutator determine the rotation speed, not the line frequency. They will even work on DC.Following this procedure is a good way to convert an outlet from 120V to 240V for appliances like air conditioners, provided the outlet is the only outlet controlled by the breaker.
If you wish to add an outlet to the existing wiring system, then installing the new outlet will take a few hours. Whenever the option is available, it is best to connect a dual voltage motor to the higher voltage. This article better describes why: Should I Connect My Motor to 120 or 240 Volts. Make that the new breaker only covers the converted 240V outlet. Otherwise, too much coverage will cause electrical issues and accidents. Turn on the power at the breaker in the main circuit. Use a tester to confirm that power is getting into the outlet.
Transformers are your friend!
The main problem in installing or converting the 240V outlet is you need new wires to run if the present wire does not support 240 volts. You can run a cable from a 240V circuit to the breaker box. Use a 4-strand cable gauge to operate the power rating of the breaker.
