Answer for USA, Canada and countries running a 60 Hz supply service.
The equation for amperage is Amps = Watts/Volts. As you can see the voltage is needed to give an answer.
Assuming that this is a home electric furnace and not a commercial or industrial furnace, the voltage of 240 single phase will be used.
Using the above equation A = 10000/240 = 41.6 amps. The conductors have to be rated at 125% of the devices amperage. This is 52 amps.
A #8 copper conductor with an insulation factor of 90 degrees C is rated at 55 amps. The breaker to feed this installation should be a 50 amp breaker.
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances
always use a test meter to ensure the circuit is, in fact, de-energized.

What is the kilowatt power draw of an electric furnace that measures 20 amps and 240 volts at it's power circuit?
For the furnace Watts = Amps x Volts Divide watts by 1000 to get 4.8KW.
How many amps does a 10kw heater draw that's 3phase 220volt?
40 amps
How many amps at 220 volts can be drawn from 10kw?
The formula you are looking for is I = W/E. Amps = Watts/Volts.
Will a 7000 starting amps and 10500 running amps run a 78 amp furnace?
In the electrical trade the only time there is a reference to start and running amps is when dealing with motors. The running amps is always lower than the starting amps. A 78 amp electric furnace will take a 100 amp service for it to operate and be within the electrical code guide lines.
Are there electric ranges that draw 30 amps or less?
Yes I have one that runs on a 30 amp circuit.

How many amps does a 10kw heater draw that's 3phase 220volt?
40 amps
How many amp does it take to operate an electric furnace?
Electric furnaces are rated in Kilowatts. The following formula will let you figure it out. Watts = amps x volts. For eg. a 10 Kw furnace draws 10000 watts. amps = watts/volts. 10000/240 = 41.6 amps. If your furnace differs from this example, just plug in your wattage and you will have your answer.
What is the amps In a simple electric circuit with a 12 volt supply and a 24 ohm resistor?
0.5 amps
How many amps at 220 volts can be drawn from 10kw?
The formula you are looking for is I = W/E. Amps = Watts/Volts.
How many amperage in 10KW?
The formula you are looking for is I = W/E. Amps = Watts/Volts. As you can see a voltage must be stated to answer this question. 10kW = 10000 watts.
Will a 7000 starting amps and 10500 running amps run a 78 amp furnace?
In the electrical trade the only time there is a reference to start and running amps is when dealing with motors. The running amps is always lower than the starting amps. A 78 amp electric furnace will take a 100 amp service for it to operate and be within the electrical code guide lines.
Are there electric ranges that draw 30 amps or less?
Yes I have one that runs on a 30 amp circuit.
What circuit breaker rating do you need for a 3 phase electric motor?
The circuit breaker is sized to the full load amps of the motor times 250%.
What size wire and breaker for a 240 volt single phase 20 kw electric furnace rated at 83.3 amps?
AWG #3 copper.
10kw heater at 220V draws how many amps?
45-50 amps. But your overcurrent protection and wire must be designed for 125% of load so the max overcurrent protection is 55 amps or 60
How many amps equal 1 circuit?
80% of the rated circuit. 10 amp circuit is 8 amps, 20 amp circuit is 16 amps, etc.
