How many kw in 480v?
The code book states that the motor will draw 1.8 amps. <<>> 1 amp
How many amps is 3KW at 480 volts 208 between legs.?
If you have 208 between legs, you have 120 from each leg to neutral (208 divided by 1.73). Assuming a balanced load, this would be 1 KW per leg - 1000 divided by 120 = 8.33 amps per leg. Your question contradicts itself. If you have 208v, the answer above is correct, 8.33 amps. If you have 480v, you have 3.6 amps.
How many amps is 1000 coulombs?
1000 Amps
How many amps is 3000 milliamps?
3 amps
How many amps equal 1300ma?
1.3 amps
Wh would someone divide16.4kva by 480v?
Answer: To determine the amperage in a circuit. Notes: Power (in watts) = Volts * Amps 16.4 KVA = 480V * Amps 16400 / 480 = Amps ~34.2 = Amps
How many kw in 480v?

How many amps does a 30HP motor use hooked to 480v 3 pH 60Hz line?
The electrical code states that a 30 HP induction motor at 460 volts three phase will draw 40 amps. <<>> I = 33.34 AMPS IF EFF.= 95% AND P.F.= 85%
How many amps in 17000 watts?
At 240v single phase it's 70.8 amps. If it runs on 2 wires plus ground, take the voltage rating of the equipment and divide that into the watts to get amps. At 480v 3 phase it's 25.8 amps. At 208v 3 phase it's 47.2 amps. <<>> There are zero amps in 14 kW. A voltage needs to be stated. I = W/E, Amps = Watts/Volts.
How many output amps is a 45 kva transformer?
There is not enough information provided to answer. KVA is short for "Kilo Volt Amperes". That is, thousands of Volt Amps. In order to determine how many Amperes are flowing, you must know at what voltage it is operating. Amperes = 45,000 ÷ volts Bill Slugg
A 100 amp 3 phase power supply is good for how many total amps?
100 amps to a 3 phase load. Power = 100A x Voltage x 1.73 ((line to line voltage)(1.73=SQRT(3)). 173 amps to each of 3 single phase (line to line) loads. Power = 173A x Voltage (line to line voltage). or... 100 amps to each of 3 single phase (line to neutral) load. Power = 300A x Voltage (line to neutral voltage). Example: - 3 phase, 480v, 100amp to a 3 phase heater. 100A x 480V x 1.73 = 83040 watts. - 3 single phase 480v (L-L voltage) heaters, 100amp. 173A x 480V = 83040 watts. - 3 single phase 277v (L-N voltage) heaters, 100amp. 300A x 277V = 83100 watts.
How many amps is 3KW at 480 volts 208 between legs.?
If you have 208 between legs, you have 120 from each leg to neutral (208 divided by 1.73). Assuming a balanced load, this would be 1 KW per leg - 1000 divided by 120 = 8.33 amps per leg. Your question contradicts itself. If you have 208v, the answer above is correct, 8.33 amps. If you have 480v, you have 3.6 amps.
A 240V to 480V Step up transformer with a load of 85 amps at 480v what amperage will the transformer draw if the primary is 240V?
Since this transformer has a ratio of 1:2 the load current on the 480V side just has to be doubled. 85 x 2 = 170A on the primary. 40.8 KVA transformer. To prove this just find the KVA of both sides and they should be equal.
How many output amps is a 75 kva 208v-480v?
1kw=1.25kvaby this relation 75kva=60kwp=1.732*380*I*1I=60000/1.732*380*1I=91AmpsCommentPower factor is irrelevant to this question. You don't need to convert the kV.A rating to kilowatts, simply divide 75 000 V.A by (1.732 x 380). The answer is 114 A.This, of course, assumes that the question refers to a three-phase generator and that 380 V is the line voltage.
How many amps does 350hp motor 480v 3 phase draw when operating?
The formula you are looking for is; Amps = HP x 746/1.73 x Volts x %eff x pf. 350 x746/1.73 x 480 x .90 x .90 = 261100/672 = 389 amps. This amperage assumes that the efficiency of the motor is at 90% and the power factor of the motor is also at 90%.
How do you power a 480V device from 120V home or kitchen outlet?
A: My advice is do not try it 120 v will require 480v /120 or 4 times the current. assuming 100% efficiency. a transformer can do it but there will be a loss of 20% . House wiring is 15 amps per circuit . So if your whatever unit needs more the 3 amps it just cannot be done. A PWM can also do this job more efficiently but then again the total power is in question.
How many amps can 30 kva transformer 575 volts to 480 volts gives?
for three phase the calculation is 30,000 = 1.73*V*I - simple as that. For single Phase the calculation is 30,000 = V*I - simple as that It is important to note the voltage in the first line is Line to Line (typically how it is specified in three phase power systems), and the second line it is Line to neutral. A 30KVA transformer is the same as 30,000VA to find out the Amps you need to divide the voltage if the transformer is single phase for example: 30,000VA / 480V = 62.5 Amps The calculation for a 3 phase transformer is the VA / voltage / 1.73 for example: 30,000VA /480V / 1.73 = 36.12 Amps
