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. There's one more hitch: what's the capacity of the generator? (again in watts or VA). If the generator doesn't have enough watts, then it cannot start the air conditioner. That's likely. Generators which are 120V-only tend to be small, and air conditioners which are 240V tend to be large. You might have to add a new circuit to the electrical panel to run the wires. This method is also easy, but it takes time. Ensure that you have identified the correct circuit breaker for this circuit, and now plan as to where you are able to fit in the new 15A/240V, 2-pole breaker. While you are allowed to add some length and make a splice inside the panel, it’s best if the wires will reach the new breaker location without doing so. Make sure that if you have to move breakers around to do this, take the time to modify the panel schedule to identify the circuit breaker positions that you moved. A step-up 120V to 220-240V converter is another alternative to converting 120V to 220-240v. In many situations, it is simpler and more cost-effective to convert two 120V outlets into a source of 240V without modifying existing circuits. Plus, it's an easy DIY installation!

If it has an extra horizontal bit (like this), then you can't do it if the A/C unit takes more than 2400 watts.You need two hot wires and a neutral wire for 240V circuits so that they can carry enough electricity to the plugged-in appliance. By connecting the converter to two independent sources (different phases) of 120V, the 240V step-up converter creates one source of 240V power. As a result, the 240V step-up converter can power a wide range of machinery and equipment, for homes, offices, and more. Wiring a 240V outlet for conversion will let you run multiple heavy-duty appliances and garage tools.

If you wish to add an outlet to the existing wiring system, then installing the new outlet will take a few hours. If the compressor is supplied with a cord, you will need to change the cord end to a 15A, 240V cord cap, and the receptacle to match (NEMA 6-15R). A normal 120V outlet will have a 120V wire, a neutral wire, and a ground wire. A 240V outlet will have two 120V wires and one neutral wire. Converters are lighter, more compact, affordable and support higher net wattages than high wattage transformers. Always turn off the power to work on your house’s electrical system. How to wire a 240V electrical outlet?

Converting a 120V Outlet to 240V

outlet can power virtually any standard device you can imagine, from tiny handheld electronics to large appliances. However, the item you want to use may require the higher 240V (220v, 230v) outlet. Fortunately, converting your outlet from 120V to 240V is a relatively simple project. Moreover, buying a reliable voltage converter will make the job even easier. Most lighting systems work quite well on either frequency. Those that do not have transformers in them that overheat on lower frequency 50 Hz power.
