3 amps on 120 volts is almost 1/2 hp. To be exact 0.48 hp, that's why I said almost 0.5 hp or 1/2 hp.
So say you are thinking of buying a 3 amp grinder or table top sander and you want to know about how many HP (Horse Power) it is, the answer is 120 volts X 3 amps = 360 X 0.00134 = 0.4824 HP which is almost a 1/2 HP
you can do the math from there if its a 6 amp motor then its almost a 1 HP motor or to be exact 0.4824 X 2 = 0.9648 also almost 1 HP. This is if you are on 120 volts. If you are on 110 or 125 volts its about the same.
For a single phase 3 HP motor at 208 volts the amperage is 18.7 amps. For a three phase 3 HP motor at 208 volts the amperage is 10.5 amps. This figure is derived at by taking the full load amps at 230 volts and adding 10%. As the voltage goes down the amperage goes up. For 200 volt motors 15% is added to the FLA of a 230 volt motor.
3000 milliamps is equal to 3 amps. To convert milliamps to amps, you divide by 1000.
100 amps
3 AA batteries provide about 4.5 volts. The amps depend on the load but for D-cells a load of 10 amps can be sustained for short periods.
6,25AnswerWithout knowing the efficiency of the motor, it's impossible to tell. The horsepower rating of a motor describes its output power; you need to know its input power in order to calculate its current.

It uses 2 amps
3/0 gauge
60 amps
106 amps
The main breaker is not based on the HP of the motor it is based on the FLA of the motor. Many different motors have different characteristics and all of the different motors have different amperages Once you have the amperage of the motor the breaker is 250% times the FLA of the motor.
100 amps
1100 watts or about ten amps then another 3 to 4 amps for turn table light and fan
3 AA batteries provide about 4.5 volts. The amps depend on the load but for D-cells a load of 10 amps can be sustained for short periods.
