Answer for USA, Canada and countries running a 60 Hz supply service.
No. Even though 240 volts uses two breakers it is still classed as a single phase service. Kirchhoff's law states that current entering a circuit is equal to current leaving the circuit. Since the appliance draws 10 amps, the whole circuit has 10 amps flowing through it.
Still 30 amps, but at 240 V you'll have twice the watts that you would on a 120 V, 30 amp circuit, and after all, watts are what actually does the work.
Typically single phase motors go up to 10hp. Wouldn't be very efficient at about 100 amps. A 20hp 3 phase motor at 230v pulls 52 amps. The 10hp single phase 230v pulls 50 amps.
To calculate the output amps of a 600kVA generator at 240V, you would use the formula Amps = kVA / Volts. In this case, it would be 600kVA / 240V = 2500 amps.
At 240v single phase it's 70.8 amps. If it runs on 2 wires plus ground, take the voltage rating of the equipment and divide that into the watts to get amps. At 480v 3 phase it's 25.8 amps. At 208v 3 phase it's 47.2 amps. <<>> There are zero amps in 14 kW. A voltage needs to be stated. I = W/E, Amps = Watts/Volts.
There is zero watts in 10 amps.
A 240V well pump typically draws around 10-15 amps.
This depends on what voltage the range is rated for and if it is single phase or three phase. At 220 volts single phase it is about 60 amps, 240 v single phase , 53 amps and at 480 v three phase about 15 amps.
Power = volts times amps, so an appliance drawing 10 amps at a line voltage of 110 volts is consuming 1,100 watts. Keep in mind, however, that in a non purely resistive load, the phase angle of amps to volts might not be zero degrees, so the calculation becomes more complex, and depends on power factor, or phase angle.
The basic formula for the Voltage, Current, Power relationship is P=I*E. To find one when the other two are known, simply fill in the two you know and solve. In this case P=1000W and Voltage = 240V (It is important that you pay attention to the unit definer here, if it were 240 mV, you would have Voltage = .240V and so on). 1000W = I * 240V I = 1000W/240V I = 4.17A
A 1,000 watt inverter giving 110 volts is rated at 9 amps.
Yes, 220 and 240 volts are a nominal figure in the same voltage range. It is brought about by the power company, as they have a responsibility to keep voltages within a certain 10% range. The load will only notice a difference of 1% on the load current. e.g. Wattage load of 2400. Amps = watts/volts. 2400/240V = 10 amps. 2400/220V = 10.9 amps. On a constant resistance as the voltage goes lower, the current goes higher and vice versa as the voltage goes higher, the current goes lower.
Typically 75 amps on natural gas, 85 amps using propane. Peak amps(for less than a second) to start a big appliance, like an A/C condenser, are 130.
