What is the running amps of a 45 kW motor?
To answer this question the motor's voltage must be stated and whether the supply voltage is single phase or three phase.
How do you calculate the phase current when working with a 10kw 3 phase electrical motor?
The 3 phase formula you are looking for is I = HP x 746/1.73 x E x% Eff x pf. Where I = amps, E = voltage, %Eff = percent efficiency of the motor and pf = power factor.
How many amps will a 3 hp motor pull on 230 volts?
It depends on the voltage of the motor, and whether it is single-phase or 3-phase. A 120 VAC 2HP single phase motor draws almost 20 amps, a 240 VAC single-phase 2HP motor draws about 10 amps. A 480 VAC 2HP three-phase motor only draws about 6 amps.
How do I calculate the watts used by a service panel using the amps of the three phases do I sum the current and multiply by the voltage or do I average the 3 phases' current x V x 1.73?
Sum the current and multiply by the line to ground voltage. Never use the phase to phase voltage unless you're dealiing with a dedicated load using all three phases like a 3 phase motor.
How many amps is equal to 270 cca?
If you know the voltage you can calculate the amps. . Ampere I = power P / voltage V .

How do you calculate watts to amps?
The most basic calculation is volts multiplied by amps of a circuit for a single phase load.
How do you calculate kva from amps?
At what voltage? If you know the voltage then, to get the amps those kilovolt-amps contain, you simply divide the kilovolt-amps by the voltage.

It depends on the voltage of the motor, and whether it is single-phase or 3-phase. A 120 VAC 2HP single phase motor draws almost 20 amps, a 240 VAC single-phase 2HP motor draws about 10 amps. A 480 VAC 2HP three-phase motor only draws about 6 amps.
How do you calculate the no-load current of a three phase induction motor?
All transformers, single phase or three phase have a "no-load current" rating. That is simply the nameplate rating of the Xformer in VA, (volt-amps) or KVA (1000Volt-amps) for larger Xformers. Simply divide the nameplate rating in VA or KVA by the supply voltage and you'll get the Xformers potential maximum output in ampheres.
How do I calculate the watts used by a service panel using the amps of the three phases do I sum the current and multiply by the voltage or do I average the 3 phases' current x V x 1.73?
Sum the current and multiply by the line to ground voltage. Never use the phase to phase voltage unless you're dealiing with a dedicated load using all three phases like a 3 phase motor.
What is the cable size for a 168 kilowatt 3 phase motor?
First of all find out what voltage the motor is designed to work on.
What is the phase current of a three phase 2.2kw 415v motor connected in star?
The line current would be the same if the motor were connected in delta. The current can be based on the rule of thumb which says 7 amps must be allowed for a 1-HP single-phase motor on 240 v. A 2.2 kW motor is three times as powerful, and on a three-phase supply of the same voltage (240/415) it would draw 7 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
How do you calculate full load in single phase circuit?
The question has to be more specific. Full load amps, watts or voltage. Please restate your question.
What is the rating of circuit breaker needed for a 500kva load?
To answer this question a voltage needs to be stated and whether the load is three phase or single phase. Without the voltage the amperage can not be calculated. For single phase, Amps = kva x 1000/voltage, for three phase, Amps = kva x 1000/1.73 x voltage.
