What is the approximate horsepower rating of a 240V motor that draws 15.5A of current?

A motor that draws 14 amps on 240 volts is probably a two horsepower motor, but it could be three depending on the efficiency.
Watts = amps x volts. There are 746 watts in 1 horsepower.
CommentIn North America, horsepower is always used to describe the output power of a motor. You can only find the input power by multiplying the supply voltage by the load current. You will, unfortunately, then need to know the efficiency of the machine to determine its output power in horsepower.

∙ 16y agoone horsepower is equal to about 750 watts....So you would multiply the amps times the volys to get watts.....240 x 15.5= 3,720 / 750 =4.96 hp...the approximate horsepower would be 5 hp

What is the fuse rating for a kettle?
A standard 3kW immersion heater will require a fuse rating of 13 A. This is because, it draws a current of 12 A.
What has more power a 5 amp grass trimmer or a 18 volt one?
At a specific voltage the higher the amperage the higher the rated horsepower of the motor. You will see the amperage rating used when manufactures sell hand tools. A saw that draws 12 amps, it is stated, is better than the saw that draws 9 amps. As the question stands a comparison can not be made between voltage and amps.
Is a crunch amp a good amp?
No, they overheat and chip out a draws too much current.
What size resistor do you need to power a 14 volt bulb from a 120 outlet?
To find the resistance necessary, one would need to know how much current the bulb draws. If one knows the current the bulb draws, then one would subtract the 14 volts from 120 volts then divide that by the current the bulb draws and one will find the resistance needed. Once this has been done, one would need to multiply the current drawn by the voltage drop to get the wattage rating necessary. Another important detail to note is that the power dissipated by the resistor will be much greater than the power consumed by the bulb itself. Finally if the bulb burns out the voltage across the contacts will be 120V. I would not recommend using this method to drop the voltage for the bulb.
Does an electric heater use less kwh on lower setting?
Yes. It draws less current.

A standard 3kW immersion heater will require a fuse rating of 13 A. This is because, it draws a current of 12 A.
What is the Horsepower rating for starter motor?
To determine this you will have to measure the amperage the starter draws when you crank the engine. This amperage times the voltage (12 volts) will give you the wattage. There are 746 watts to 1 HP.
Why ups rating in ampere hour?
An ups consists of battries as the main components .Batteries store charge (charge=current*time)... hence its units is so. ex. if its rating is 6AH and the load connected to in draws 1A, then the batter lasts for 1 hr.
What size wire is needed to operate a three quarter horsepower opener 250 ft from the breaker?
Wire size is calculated from the amount of current the load draws. More information is needed. Voltage and amperage will do fine.
An electric iron always draws a current of 3.4 amp from the 220v supply line what current will this electric iron draws when connected to 110v supply line?
1.7amp

How do you power a whole house with one generator?
Use a generator with a high enough rating to power the house, of course. Trying to power a house that draws 60A of current with a 10A generator is just never going to work.
A heater draws 8.70 amps on a 110 volt line What is its wattage rating?
Power = Voltage x Current P=V.I Power (in Watts) = 110V x 8.70A = 957W (Appx. 1kW) - Neeraj Sharma
A video monitor draws 1.5 A at a voltage of 150 V. What is the power rating of the monitor?
225W
What does the watts rating on a stereo speaker mean?
how much energy it draws from your outlet or car battery.
What are the circuit requirements to power 8 computers?
It depends on how much current each computer draws. An average rating for a computer power supply for a home computer is about 250 watts. A 20 amp circuit breaker can handle about 8 of this type of computer.
How many amps does a 1.5 hp dc motor draw?
1 horsepower is equal to 0.7456 kWatts, therefore 1.1184 kWatts will be the power consumption of that motor. The current draw depends on the voltage, simply use the P=UxI or I=P/U formulas to figure out the current draw (P=1118.4 Watts). some voltages: 12Vdc draw 93.2Amps 24Vdc draws 46.6Amps 110Vdc draws 10.17Amps 230Vdc draws 4.86Amps
