220 volt is single phase, so power is the straightforward IxE calculation.
30V X 220A = 6600W = 6.6KW

∙ 11y agoThe formula for wattage is W = Amps x Volts. Without the circuit voltage the amperage can not be calculated. kW = A x V x pf/1000. pf is the power factor.

How many amps does a 60 hp 460 volt motor draw?
750 watts per horse power20 x 750 = 15,000 watts / 220V = 68A68 amps at 220 volts
How do you measure the resistance of a 30-amp cartridge fuse in ohms?
Set a Volt-Ohm meter to Ohms and put the two leads from meter across the fuse. One on each end where the metal is located. The meter should read zero ohms if the fuse is NOT blown.
In order for a 30 volt 90 watt lamp to work properly in a 120 volt supply the required series resister in ohm is?
A 30 volt 90 watt lamp has 3 amps going through it. The series resistor also has 3 amps going through it, by Kirchoff's current law. The voltage across the resistor is 90 volts. With 3 amps, that is 30 ohms. (By the way... The resistor must be rated to carry 270 watts. That is a lot of power for a resistor.)
Do you have a Schematic for power amp model Mt 125?
There are schematics available on the web for about $30 plus shipping and handling.
What size breaker would you use on a washing machine circuit?
A Stadard washing machine uses a dedicated 15 Amp single pole breaker. Nothing else should be on the circuit.AnswerThe above answer applies to North America. In the UK, a washing machine is connected to the ring main system using a three-pin plug that requires a 13-A fuse.
Is there an adapter that can be used on 230 volt 30 amp air conditioner appliance to make it fit a 220 volt 20 amp socket safely?
My electrician says no, has to be some rewiring.
Does a double 30 amp breaker mean you have 60 amps for a 220 outlet?
breakers are rated by wire size, not voltage. the appliance manufacturer will probably specify amperage.
How do I make a 30 amp 250 volt line output only 220 volts at 30 amps?
you get a transformer...
Will a 30 volt 1.0A ac adapter burn out a 15 volt 1100mA appliance?
The answer to this question is yes. The 30 volt adapter will supply twice the voltage required by the 15 amp appliance. The other thing is that 1 amp is equal to 1000 mA. Even if the voltages were the same, the output current of 1000 mA when 1100 mA is needed, is not enough to supply the appliance.
Can you use a neutral wire from a existing 110 volt 20 amp circuit to supply a neutral for a washer dryer combo that has only a 220 volt 30 amp 2 wire?
No !
What fuses are needed for 240 volt appliances?
You need to be more specific about the appliance - dryer or range or air condition- 30 Amp for the dryer, 50 Amp for the range, A/C varies.
Can you plug a 120 Volt 30 Amp tanning bed into a 125 Volt 30 Amp outlet?
yes
I have a 220 volt 30 amp generator and 15 amp 240 volt light what do you need to do to make this work?
Nothing, just plug it in. Although the generator has the ability to produce up to 30 amps, the light will only pull 15, this will allow you to utilize the generator to run other items as well...
What wire size do I need for 30 amp 220v at 175'?
A #6 copper conductor will limit the voltage drop to3% or less when supplying 30 amps for 175 feet on a 220 volt system.
What is the difference in 30 amp 250 volt and 30 amp 600 volt?
Devices are rated by voltage and amperage. If you have a source rated for 600 volts you can use a 250 volt device, but not vice versa.
How do I know if I have a 30 amp breaker at my house to plug a trailer into?
If it is a 30 amp breaker then it is a 240 volt outlet.
What size cable is required for 220 v with twin 30 amp breakers?
#10 wire is used on a 30 amp service.
