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?
The kilowatt power draw of the electric furnace can be calculated using the formula: Power (kW) = Current (A) x Voltage (V) / 1000. Plugging in the values (20 A and 240 V) into the formula, we get: Power = 20 A x 240 V / 1000 = 4.8 kW. Therefore, the electric furnace has a power draw of 4.8 kilowatts.
What is 4 amps?
4 amps is a unit of electric current that measures the rate of flow of electric charge. It is equivalent to 4 coulombs of charge passing through a point in a circuit per second. Amps are commonly used to measure the strength of an electric current in a circuit.
What are electrical amps?
Electrical amps, or amperes, are a unit of measurement for electric current. They represent the rate of flow of electric charge in a circuit. One ampere is defined as one coulomb of charge passing through a point in a circuit in one second.
10kw heater at 220V draws how many amps?
A 10kW heater at 220V would draw approximately 45.45 amps. This can be calculated using the formula: Amps = Watts / Volts. So, 10,000 Watts / 220 Volts = 45.45 amps.
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.

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.

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.
What does the word amps mean in science?
In science, amps refer to amperes, which is the unit used to measure electric current. It represents the rate of flow of electric charge in a circuit.
10kw heater at 220V draws how many amps?
A 10kW heater at 220V would draw approximately 45.45 amps. This can be calculated using the formula: Amps = Watts / Volts. So, 10,000 Watts / 220 Volts = 45.45 amps.

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.
How many amps does a 10kw heater draw that's 3phase 220volt?
To calculate the amperage for a 10kW heater on a 3-phase 220V system, use the formula: Amps = (kW x 1000) / (√3 x Volts). So, Amps = (10 x 1000) / (√3 x 220) = 26.18 amps per phase. Therefore, the total current drawn by the heater is 26.18 amps per phase multiplied by 3, which equals approximately 78.54 amps.
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 is 0.78 amps?
0.78 amps is a measure of electric current. It represents the flow of electric charge per unit of time. This value indicates how much current is passing through a circuit or device at a given time.
