Converting HP to Amps: A general step for converting HP to amps for all types of circuit is given as: Step1: converting HP to watts, by multiplying HP with 746. Step2: dividing watts with

Answer (1 of 3): At 440 volts,300 hp motors will draw about 425 Amp current at full load.so,400 mm2 copper or 500mm2 Aluminium cable will be needed.

RLA - "Running Load Amps" - current drawn during normal operation of electric motor. FLA - "Full Load Amps" - amount of current drawn when full-load torque and horsepower is reached for the motor.FLA is usually determined in laboratory tests.Note! - in the calculator above FLA is RLA + 25%. 1 hp = 0.745 kW; Related Mobile Apps from The Engineering ToolBox

Its voltage is 220V, while the power factor is 0.8 with an efficiency of 90%. With these values in mind, we'll arrive at the following equation: I = (25 x 746) / (√3 x 220 x 0.8 x 0.9) The total pullout current is 67.98 amperes. 2. Get the exact ampere rating relative to the type of circuit breaker you're using.

I have stated that the 300 HP motor driving a 250 HP load will A 100 HP motor can perhaps demand 110 amps or so when delivering 100 HP,

Jan 15,  · For sizing branch circuit conductors you need to use the table values in accordance with 430.6 so for a 300 HP 460 volt motor you would use 361 amps. Also 500 Kcmil copper wire is rated at 430 amps at 90 degrees, unless the terminals are listed for 90 degrees you can not use that value.

Mechanical: 300 hp, 250 hp, 225 hp. Yamaha's award-winning V6 4.2-liter outboards have been offshore favorites for more than a decade. Initially, boaters were attracted to their power, efficiency and intelligent design. After years of proven performance, our V6 4.2-liters have become known for something perhaps even more valuable offshore

How to Convert Horsepower to Amps · Amps = (Horsepower × 746) ÷ Efficiency ÷ Volts · Watts = Horsepower × 746 · Watts = Watts / η · Amps = Watts ÷ Volts · Amps = HP
