Is it common to use a 4160 V 3 Phase motor with a variable speed drive?
No, a 4160 volt motor with a high inertia load will use a resistor bank in the starting of the motor.
What color code is used for 4160 volt labels?
Wow your in some serious stuff. Are you worried about rotation. 4160 is not something to be messed with if your not a qualified electrician or lineman. If you mess up you can have a big fire ball on your hands.
How many amps does a 50HP 460V motor draw?
To answer this question voltage, power factor, efficiency, and run configuration must be known, none of which was given in the question. I will make some assumptions, to shown how the calculation is done. Given: 50 HP, three phase. Assumed: 480 volts delta, 0.92 PF, 0.95 EF, and WYE-DELTA start-run configuration. 1 HP (electric motor) is 746 watts, so 50 HP is 37.3 KW. Divide by PF 0.92 and by 0.95 EF to get 42.7 KVA. Divide by 480 V and by 3 to get 29.6 A per winding. Multiply by 1.732 (square root of 3) to get 51.3 A per phase. Now, 51.3A is a lot of current, requiring large windings and, therefore, a large motor. I would consider a higher voltage motor, such as 4160. Rerun the calculations and you get 5.9A per phase. Does this justify a 4160 service? Its marginal, but you begin to see the issues involved in choosing a motor.
What is the amperage of a 400 HP 4160 volt 3 phase motor?
The formula you are looking for is I = kW x 1000/1.73 x E x pf. I = 1.5 x 1000 = 1500. 1500/1.73 x 400 x .86 = 1500/595 = 2.5 amps. 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. A feeder for a motor has to be rated at 125% of the motors full load amps 2.5 x 125% = 3.1 amps A #14 copper conductor with an insulation rating of 90 degrees C is rated at 15 amps.
How can you get 230v single phase from 240v single phase supply?
Most modern homes have 240 Volts supplied. The 240 volts are measured between the two main busbars in the electric panel. The way the panel is organized you just need a 240 breaker that spans both busbars. They are double the height of a 120 V breaker. If you have an electric dryer, stove or whole house air conditioner you are likely already using 240 V. If for some strange reason you don't already have 240 V then you would need a transformer rated to your intended use.
What is 4160 Volt electrical wire insulation rated for?
You can use an insulation rating 5000 volt to run 4160 volt supply.
Is it common to use a 4160 V 3 Phase motor with a variable speed drive?
No, a 4160 volt motor with a high inertia load will use a resistor bank in the starting of the motor.
What is 4160 - 800?
4160 - 800 = 3360

What is the Y in 480Y voltage?
The Wye (also know as Star - especially in the motor rewind industry) is a 4-wire system which provides two different supply voltages. The center-point of the Wye is the system neutral and is usually solidly grounded. Where it is desirable to limit the phase-to-ground fault magnitude the center-point of the Wye may be connected to ground through and neutral grounding resistor or a current limiting reactor. Because the system is tied to ground it is easy to provide system ground fault protection. Three-phase loads can be connected phase-to-phase and singlephase loads can be connected from any phase to the system neutral. On a wye system, the phase unbalance currentis carried by the system neutral. On a Wye system the line current is equal to the phase current i.e. ( ILine 1 = IPhase A) and the line-to-line voltage is equal to the vector sum of two individual phase voltages i.e. (E Line1-2 = E PhaseA + E PhaseB' ). In a Wye system the phase-to-phase voltage is 1.732 x the phase-to-ground voltage. Some typical Wye system voltages are: 120/208Y, 277/480Y, 2400/4160Y, 4160/7200Y, 7200/12470Y, 7620/13200Y,and 19920/34500Y
What is the voltage-to-ground on a 4160 V delta circuit?
There should be no voltage to ground on a delta system. That is the reason that these types of systems have to have a set of grounding lights to warn when the system inadvertently grounds. A delta system is a three wire connection, no neutral. A voltage to ground is only available on a three phase four wire (star or wye) connection system. The fourth wire being a neutral which is grounded thereby giving a voltage from each leg to neutral.
