Wire is sized by the load amperage. The formula for amperage when the HP is known is I = HP x 746/1.73 x E X %eff x pf.
A standard motor's efficiency between 5 to 100 HP is .84 to .91.
A standard motor's power factor between 10 to 100 HP is .86 to .92.
I = 60 x 746 = 44760/ 1.73 x 480 x .89 x .89 = 44760/658 = 68 amps.
Motor feeders have to be sized to 125% of the motors full load amps. 68 x 125% = 85 amps
A #3 copper conductor will limit the voltage drop to3% or less when supplying 85 amps for 220 feet on a 480 volt system.
What else can I help you with?
What is the start up amps on a 200 hp 3 phase 480 volt motor?
i have 200 hp motor what i need cable size in 100 feet distance
What size wire do I need for a 60 amp service either 750 feet or 500 feet away?
It depends on the supply voltage because at that distance the size of the wire is calculated on the volt-drop which is 5% of the supply voltage, or 3% in some countries. The allowable resistance equals the volt-drop divided by the current, then you can use wire tables to find the wire size, remembering that a supply needs 2 wires which are in series so that their resistances add. <<>> To answer this question a voltage value has to be stated. This is due to the higher the voltage the lower the current on a specific load. The lower the current, the smaller the wire size can be.
Can you run a 570 volt motor on 480 volt three phase power supply?
No, it is not recommended to run a 570 volt motor on a 480 volt power supply. The motor is rated for a specific voltage to ensure optimal performance and prevent damage. Running the motor at a lower voltage could result in overheating and premature failure.
Can you run a 220 volt 1 horse motor with batteries?
Yes, you can run a 220 volt 1 horsepower motor with batteries by using an inverter to convert the DC power from the batteries into AC power that the motor can use. However, the size and number of batteries needed will depend on the motor's power requirements and the duration for which you want to run it.
What size wire needed for 200 amp service 400 feet away direct buried single phase 240 volt 3 wire?
Assuming you are working with 240v, you need 4/0 copper conductors.
What is the start up amps on a 200 hp 3 phase 480 volt motor?
i have 200 hp motor what i need cable size in 100 feet distance
What size battery do you need for a 4.5 volt DC motor?
4.5 volt battery sold only in Russo
What kind and length of electrical wire do you need for a 2 hp single phase 220 volt motor 50 feet away?
The motor would take 10-12 amps which would need wire of 1.5 mm2 or larger. For a permanent installation use the next size, 2.5 mm2 cross section.
What the the correct size capacitor for a three quarter horsepower 110 volt motor?
110v 40 uf
What size wire for 240 volts 200 amp service 200 feet away?
A 3/0 copper conductor will limit the voltage drop to 3% or less when supplying 200 amps for 200 feet on a 240 volt system.
Can you use a 3 volt battery to run an 8 volt motor?
You can but the motor may not run, however you will not burn the motor.
Can you run 22 kw 600v 3 phase induction motor?
Yes this size motor can be operated by bringing a 600 volt three phase supply to it.
Can a put a Receiver from a lower Volt motor to a Higher Volt motor so i can control it with the transmitter i have?
NO
