The equation for amperage is Amps = Watts/Volts = 10000/240 = 41.6 amps. It is not stated if this is a motor load or not. If it is a motor load then the feeder has to be rated at 125% x 41.6 = 52 amp wire. Also if it is a motor load then the breaker will have to be 250% x 41.6 = 104 amps. A 100 amp breaker will work and still be within the electrical code ruling. Otherwise for 41.6 amps a 50 amp breaker will be sufficient.

How many amps circuit to use on a 10kw electric furnace?
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 appliancesalways use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
