One horsepower electric is 746 watts. Divide that by 415 to get amps, giving about 1.8. Divide that further by 3 because it is three phase power, giving about 0.6. Divide that further by power factor to compensate for apparent versus true power caused by reactance, say about 0.8, giving about 0.75.
What else can I help you with?
7200 volt 25kw transformer how many amps at 240 single phase?
The formula you are looking for is I = W/E. Amps = Watts/Volts.
What is the amps of a 5.5 kw 480 volt 3 phase?
Current in 200kw at 480 volts = 200,000/480 = 416.667 amps
What is the amperage for a 20000 volt-amp heating unit on a 240 volt single phase circuit?
Volt amps is the same way of saying watts. This is seen in the formula Watts = Volts x Amps. Using the formula I = W/E we transpose I = 20000/240 = 83.33 amps.
How many output amps is a 75 KVA generator?
It depends upon the Generator system voltage. For 3 Phase, 600 Volt system, it will be 73 Amps For 3 Phase, 480 Volt system, it will be 90 Amps For 3 Phase, 208 Volt system, it will be 208 Amps
Fuse size for 7.5 HP 3 Phase 440 Volt Motor?
The electrical code states that a 7.5 HP 460 volt three phase motor draws 11 amps. For fuse sizes, non time delay - 30 amps, time delay type D - 20 amps and if using a breaker it will be 30 amps. Minimum wire size is #12 and the maximum setting of overload devices will be 13.75 amps

How much amps of 3000watts on 220volt ac single phase?
To calculate the amperage, use the formula: Amps = Watts / Volts. For a 3000-watt load on a 220-volt AC single-phase circuit, the amperage would be approximately 13.6 amps.
How do you calculate volts with volt amperes?
Divide the circuits amperage into the volt amps and you will get the voltage.
How many amps will a 240 volt single phase 15 kva generator supply?
62.5 amps
How many amps is 6kW 240 volt single phase?
The equation that you are looking for is Amps = Watts/Volts. There are 6000 watts in 6kW.
How many amps will a 3 phase 480 volt 4kw heater draw?
To calculate the amperage drawn by the heater, you can use the formula: Amperage (A) = Power (W) / (Voltage (V) * Square root of 3). In this case, the amperage drawn will be approximately 5.8 Amps.
How many amps are in 40 volt amps?
Multiply the vots by the amps to find the volt-amps. Or divide the volt-amps by the voltage to find the amps.

How do you calculate power for a delta connected three phase autotransformer?
The maximum power output of the transformer is measured in VA or KVA, (volt-amps) or thousand (volt-amps). That will will marked or stamped on the transformer. If you want to measure the amount of power being used by the Xformer, measure the Line side current in amps with an amprobe and multiply by the line voltage to it. The result in watts is the power consumption.
