Given 1hp motor
how to compute the exact amount of amphere use in circuit breaker
You're not going to be able to do this with just a known Horse Power.
There are 3 elements to the equation, with any two, you can work out the third.
If you want to know how the amperage, you will need to know the voltage and wattage of the motor. I imagine that you already know the voltage (It's going to be 220V or 110 volt)
Watts divided by volts = Amps
A 220v 1000 watt motor (1000 divided by 220) will draw 4.55 amps
A 110v 800 watt motor (800 divided by 110) will draw 7.27 amps
Bear in mind that most washing machines have a couple of windings for wash and spin. As an average, the was winding will usually be about 500 watts to spin and about 250 watts to wash. ALSO, bear in mind that if you are using this data for a WASHING MACHINE, then there is a water heating element in there too and that draws about 2Kw (2000 watts)
Dont just take this as read, you DO need to check wattages, but, working on what I have just said, the max consumption on a 220V machine will look like this:
At Spin, with a 500 Watt consumption: (500/220) = 2.3 amps
While Washing with a 250 watt consumption: (250/220) = 1.14 amps
Consider that the WASH and HEAT may be running at the same time.
2Kw heating (2000/220) = 9.1 amps PLUS 1.14 amps for the motor - Total wattage 10.24 amps
Watts / Volts = Amps
Amps x Volts = Watts
Watts divided by amps = Volts
