Most 3ph Motors are rated for both voltages. High Voltage Wiring (440-480) Connections goes as follows L1=>T1,12 L2=>T2,10 L3=>T3,11 4=>7 5=>8 6=>9. Low Voltage (220-240) goes as follows L1=>T1,6,7,12 L2=>T2,4,8,10 L3=>T3,5,9,11. "L" Denotes Line Side Voltage (Power Coming to the Motor) "T" Denotes Terminal Motor Leads. You may not have #10, 11,or 12 leads as most motors since the 1980's have been internally wired inside the windings to T1, T2, and T3 or 1, 2, and 3 which are the same wires. Usually the Junction box on the side of the motor has this already listed under it's cover. If it shows a Low and a High Configuration, you have a Dual Voltage Motor.

How many PH value for water in LRS for induction motor?
How much pH value of Liquid resistor electrolyte solution
How many amps does a 30HP motor use hooked to 480v 3 pH 60Hz line?
The electrical code states that a 30 HP induction motor at 460 volts three phase will draw 40 amps. <<>> I = 33.34 AMPS IF EFF.= 95% AND P.F.= 85%
Speed control of three phase induction motor by supply voltage control using AC voltage regulators?
No. Use standard utility AC, 3 PH voltage to feed a Variable Frequency Drive (VFD). The VFD is then wired to the motor. The output of the VFD varies average voltage and frequency in a semi-constant proportion to keep Volts/Hertz ratio the same to the motor. The operator can then adjust or select the desired speed from the VFD and the VFD will run the motor continuosly at that desired speed. If you were to control only voltage to the motor without adjusting frequency in proportion, the motor would burn up.
How do you write abbreviation for 3-phase 4-wire?
It is written 3 ph 4 w.
What cable size of wire if the machine is 50hp?
If it is a 480v 3 pH machine, #4 wire will be fine.
40hp motor 480 volts 3 pH equals amps?
108.25
Can you connect 240 3 ph motor to 480 3 ph by dropping a leg?
Absolutely not. The rated voltage of the motor must match the supply voltage or at least be within 10%. The 240 V motor will be damaged or destroyed if hooked up in this manner.
How do you run 380 three pH motor to 220 three phasesupply?
Unless it is specifically designed to run at reduced voltage, you shouldn't connect it directly. You'll need a step up transformer from 220 to 380.
How connect a transformer 380 volt 3 pH to 220 volt mono pH?
any one of the three line to neutral is 220 volts
What is the pH level of motor oil?
The pH of motor oil is approximately 5 or higher.
What were the wind speeds in cyclone yasi?
220 k/ph was the average, but it reached as high as 290 k/ph.
Optimum pH for most cell line is?
Most cells operate around a pH of 7.4
Can enzymes work over a broad range of PH levels?
Most enzymes work best at a certain pH, however there are some enzymes that can operate over a broad pH range.
What types of motor used in water pump?
Depending upon the use, it can be a 3 phaze or 1 phaze induction motor. For domestic use it has to be a 1 phaze Induction motor but for industrial use it can be a 3 ph or 1 ph I.M.
How many PH value for water in LRS for induction motor?
How much pH value of Liquid resistor electrolyte solution
What pH do enzymes in the human blood stream operate at?
The pH balance of the bloodstream is one of the most important biochemical balances in the chemistry of the human body. It is measured on a scale of 0-14.
What Oil filter on 1975 Chevy 350?
A Fram PH-13 or PH-5 should do it on any mid 70's SBC motor. That's what I run.
