It will lead to electrical burned and may cause serious consequences such as fire if the input voltage is higher than the normal. But if the input voltage is below the rated voltage, the electrical appliance can’t work normally or simply failed to work, and it may also cause damage to the motor.

Converting 220 volts to 110 volts is possible. You can convert 220 volts to 110 volts by either using an adapter plug or removing the existing 220 receptacle from the outlet box.

You can’t run a 240 volt appliance on 110 volts because it simply won’t receive enough power to operate properly and you can’t run a 110 volt appliance on 240 volts because it will burn up..

This is a rating you see on switching AC->DC converters, that indicates that it can automatically work with 110V USA style AC power, or 240V that the rest of the world uses. It means so long as you can adapt the plug using a travel adapter, it will work anywhere in the world.

If the 110V appliance is connected to a 220V power supply, the power may quadruple at the moment the appliance switched on, and the appliance will quickly operate in an overvoltage condition. It may be accompanied by smoke and flash, or the fuse will melt and the protection part will be damaged.

How to Identify 240-Volt Outlets? The 240-volt outlets are larger than 120-volt outlets, and they have rounded tops with three or four holes. The top hole of an older three-prong 240-volt plugs looks like a backward ‘L’and the other two holes are diagonally placed on the sides.

For the most part, you are going to see 120 volts, 15 amp, and 20 amp. And 220 2 wire, 3 wire, and four wire types. Please remember not all 220-volt outlets use a neutral (white) wire.

What does a 115 volt plug look like? The larger prong is “neutral” and the smaller prong is the “hot” connector. Units with these plugs use between 110 and 120 volts — standard household electricity. In some cases, a 120-volt window air conditioning unit may have a round, three-prong plug of the same configuration.
