This question makes no sense unless you mean volts instead of amps.
And no, not for residential. Your panel feeds 120 volts or 240 volts depending on the way things are hooked up. You can wire circuit that is currently connected 120 as 240, however unless it is a dedicated circuit, YOU WILL BLOW UP YOUR APPLIANCES. Consult a qualified electrician.
Yes, this can be done. The adapter will handle at 120 volts x 15 amps = 1800 watts. The adapter is just a step up transformer. The maximum 220 volt device that can be connected can only have an amperage rating of 8 amps at 220 volts.
6 amps.
A #8 AWG copper conductor with an insulation factor of 90 degrees C will limit the voltage drop to 2.26% or less when supplying 30 amps for 120 feet on a 220 volt system.
watts = volts * amps--> Amps = watts/ volts therefore; 2000/220= 9.09 amps
The difference between 220 amps and 240 amps lies in their amperage ratings. 220 amps denotes a current capacity of 220 amperes, while 240 amps indicates a current capacity of 240 amperes. The higher the amperage, the greater the power capacity for electrical devices.
The formula you are looking for is I = W/E. Amps = Watts/Volts.
LCM of 120 300 and 220 is 6600.
To convert watts to amps at 120 volts, use the formula: Amps = Watts / Volts. For 1500 watts at 120 volts, the calculation would be: 1500 watts / 120 volts = 12.5 amps.
220
Either 120 or 220 volts, depending on what part of the world you are in. If you are in the United States, most power coming out of a wall socket is at 120 volts. In Europe and elsewhere, its at 220 volts. This is why if you are traveling abroad with US-based electronics you need a converter to use them in other countries.
To find the number of amps in 200 watts at 120 volts, you can use the formula: Amps = Watts / Volts. Therefore, Amps = 200 watts / 120 volts, which equals approximately 1.67 amps.
The 220 Volt secondary in a single phase transformer rated 2kVA, should be able to deliver about 2000/220 or 9.1 Amperes, assuming unity power factor.
