depending on 1phase or 3phase voltage motor , the amphere requirement is found out
for 3phase AC motor use this formula: (HP x 746)/(1.73 x E x Eff x PF)
for 1phase AC motor : (HP x 746) / (E x Eff x PF)
Need to know the voltage of the motor.
There are 746 watts in 1 HP. Watts = amps x volts. It depends on the voltage rating of the motor. Amps = 746/volts = ? need voltage.
Need to know what the voltage of the motor is.
Read the specification plate on the motor to determine the amount of current that the motor uses, as well as the voltage and phase. Most likely, it will be a 3 phase motor, so you can't simply connect it to your house wiring, but without sufficient information, it is impossible to tell you all of the specifics. <<>> The code book rates the amperage of a three phase 40 HP motor by different voltages. at 200 volts - 120 amps, 230 volts - 104 amps, 460 volts - 52 amps and 575 volts - 52 amps. A breaker for a motor has to be sized to 250% of the motors full load amps. Also the wire size for a motor has to be 125% of the motor full load amps.
Look at the motor nameplate and it shoud have the amp draw on it. If the nameplate is missing, then the amp draw depends on what type of motor it is. The basic calculation to get you in the ball park would be as follows: 1 HP = 0.75 KW 7.5 HP = 5.63 KW Assume the efficiency of the motor is 80%, then the power supplied will need to be 5.63/0.8 = 7.04 KW amp draw = 7040/220 = 32 amps <<>> For calculation purposes the electrical code book states that a 7.5 HP motor draws 40 amps.
You have a 1961 Johnson 75hp outboard motor model no v4sl-14b need a owners manual or a print out of the motor so you can order parts for the ignition no spark can anyone help?
Need to know the voltage of the motor.
The amperage of a motor is governed by the voltage that the motor operates on. Without a voltage given, an answer can not be given.
There are 746 watts in 1 HP. Watts = amps x volts. It depends on the voltage rating of the motor. Amps = 746/volts = ? need voltage.
You asked the wrong question. You need to know how many amps the motor uses. Then you can multiply amps times volts and get watts. Then you can multiply watts by hours and get watt hours. (For house electricity you pay for kilowatt hours.) A kilowatt is 1,000 watts.

7 pocket amps
To charge a car battery you need aproximatly 8000 amps To charge a car battery you need aproximatly 8000 amps
The circuit breaker is sized to the full load amps of the motor times 250%.
you will need 21.81 amps at 220v
