If you needed to perform the same amount of work with 120 volts, you would need twice as much current. For example, a room air conditioner using 240V might use 8 amperes of current. If you cooled the same room with an A/C unit running on 120V, it would take 16 amperes of current (actually a little more because of reduced efficiency). That means your wiring will need to be larger to safely deliver the additional current to the outlet. You would also need an outlet that is rated to safely carry the higher current. In countries where 200-240 volts is normal, the entire electrical delivery system can be smaller and cheaper because of the overall reduction in current demand.
Yes, the 265 volts is just the maximum the appliance can handle. You can use it on a 240 volt circuit.
120/240 volts is the working voltage in North America.
No, a 240 volt device runs on 240, and a 120 volt device runs on 120. Attempting to run a device on incompatible voltage results in damage.
It is not just the outlet, but the wiring and breakers that need to be compatible with your 240 Volt appliance. Get an electrician to look at your requirement.
The pin configuration of the 240 volt receptacle is different from a 120 volt pin configuration. This is a safety factor to prevent the wrong voltage being applied to the wrong devices.
'Voltage' is electromotive force, and the 'Watt' is a unit of power. You can plug a 240 watt appliance (light, toy, radio etc) into a 120 volt socket as long as the appliance is rated for 120 volt AC operation.
Yes it can. It is within the normal voltage / HZ tolerance.
No, sorry but you fried it. Any voltage higher than an appliance is rated will do major damage.
No. You need a 3-phase supply that matches the voltage and current rating of your appliance.
Yes, but you are limited to the amount of current draw the 120 volt load can apply to the adapter.
If the appliance is 220 volt 60 Htz, yes it will work perfectly in the U.S. plugged into a 240 volt outlet.
No, it requires a 180 Volt supply. Most appliances work +/- 10%, in this case 162 Volts to 198 Volts. I would question whether your appliance is really 180 Volt. No country uses this as domestic supply, it is usually 110V or 220-240V.
