The formula to find amps is:
I = (KVA x 1000)/(E x 1.73)
I = (2500 x 1000) / (480 x 1.73)
I = 2500000 / 830.4
I = 3010.597A

∙ 14y ago35 kva = 35000 VA so
1.73 is the sqrt of pi and is the magic number when using 3 phase
35000/480/1.73=42 and some change

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 would full load amps be on a 480volt 90 kw electric heater be pulling 36 amps per leg?
90 kW on 480 volts single phase would be 187.5 amps. On 480 v 3-phase it would be 108 amps.
How many amp in 480 vac 3- phase primary transformer if the secondary it's 120 vac?
This 480-v three-phase transformer probably has a 208-v three-phase secondary which has 120 v from each line to neutral. In that case the primary current is 0.433 times as much as the secondary current, so 100 amps in the secondary means 43.3 amps in the primary.
What phase current is flowing in a balanced purely resistive 480V 3 Phase Delta connnected system with a demand of 96KW?
96 kW means 32 kW from each phase. If the load is star connected each resistor has 277 volts across it and carries 32,000/277 amps, 115.5 amps. The load resistors are 277/115.5 ohms or 2.40 ohms If the load is delta connected each resistor has 480 volts across it and carries 66.7 amps. The load resistors are 480/66.7 ohms or 7.20 ohms. In both cases the line current is 115.5 amps.
Formula equals volts x amps x power factor x 1.732 what is 1.732?
The figure 1.73 is the results of the square root of 3. 1.73 is used in three phase calculations. The number is also used on three phase four wire systems. To find the coil voltages of a wye system 1.73 is divided by the phase voltage. An example, three phase 480 wye system. 480/1.73 = 277 volts
How many amps will a 3 phase 480 volt 4kw heater draw?
8,33 Amps
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 amps of a 7.5 hp 480 volt 3 phase?
88 amps
How many amps do you need to supply a 150kva transformer to get 118amps 480 volts?
Rephrase your question, as it doesn't make any sense. If the primary side of the transformer is 480 volts 3 phase, this transformer can be supplied from a breaker as big as 180 amps. If 480 volts 3 phase is your secondary then you can supply up to 180 amps to your loads.
What would full load amps be on a 480volt 90 kw electric heater be pulling 36 amps per leg?
90 kW on 480 volts single phase would be 187.5 amps. On 480 v 3-phase it would be 108 amps.
How many amps will a 50KVA 3phase bank carry on 277 - 480 volts?
50 kVA is 16.667 kVA per phase and you divide that by the phase voltage. Current = 16667 / 277 = 60 Amps
1500 kva transformer equals how many amps at 480 volts?
480 volts is probably 3-phase (Line to line) voltage, so: 1500K / (480 x 1.732) = I = 1804Amps
How many watts is 1 hp at 480volts?
A 1-HP motor is reckoned to draw 7 amps at 240 v single-phase. The same power of motor would draw 3.5 amps at 480 v single-phase, but a 480 v supply could most likely be a three-phase suppy, and the current in that case would be reckoned as 2 amps.
How do you calculate 3 phase power for a motor that draws 22 amps per leg it is a 480 3 phase motor do you use 480 x 22 or 277 x 22?
1.73*480*22
What is the primary amps on a 25kva tranformer with input volts 480 Volts AC?
if it's single-phase, 25,000 divided by 480.
What amperage will a range with a rating of 12.9 kw draw?
This depends on what voltage the range is rated for and if it is single phase or three phase. At 220 volts single phase it is about 60 amps, 240 v single phase , 53 amps and at 480 v three phase about 15 amps.
480v 130kw how many amps?
Amps = Watts / Volts Amps = 130000 / 480 Amps = 270.83
