What happens when you connect a motor to a three-wire connection?

The symmetric phase displacement among the phases makes the three wire connection a balanced symmetric system. If you have connected the motor the same way it was originally connected to the same or an equivalent source and nothing happened, there are several possibilities.

What is three phase power used for?

Three-phase power is used in factories and some residential applications. Three-phase motors are more efficient than single phase motors and are commonly found in applications requiring more than 7.5 horsepower.

How do you wire a motor to a 230-volt wire?

Connect motor lead 3 to the blue L3 conductor. Connect the ground wire to the motors ground terminal. Loosen the ground terminal screw, insert the ground wire into the terminal and tighten the screw firmly. Close the motors wiring box. Make the connections for low voltage, 230-volt wiring. Connect motor leads 1, 7 and 6 to the black L1 conductor.

How do you wire a dual voltage 3 phase motor?

These instructions cover a dual voltage, three-phase motor, the most common type. Turn off the power supplying the circuit to be wired to the motor. A three-phase motor must be wired to a three-phase supply. Open the motor wiring box and identify the wires within.

What are the different types of three-phase motors?

1 Nine-Wire Three-Phase Motors. The most common type of three-phase motor is that which has nine labeled (and often colored) wires coming out of the box on the side. 2 Internal Wye Windings. ... 3 Low Voltage Wiring. ... 4 Power = Voltage2 / Resistance. ... 5 High Voltage Wiring. ...

How do you wire a three-phase power system?

Wiring any other three-phase system will be done exactly the same way. You should have three distinct terminals or wires coming out of the system which allows you to make a connection. Run a phase to each terminal and you should have power within the system.

What is a 3 phase power system?

A three-phase system is simply a system which will have three conductors which will carry current and have a certain voltage. Depending on the source, this system may also have a neutral wire for returning current back to the transformer. The most common use of three-phase power is for motors.

How do you wire a 240 volt motor to a switch?

The wiring diagram will show that two of the motor wires are connected together for 240-volt wiring. Connect the ground wire from the switch to the ground terminal in the wiring box. The ground terminal should be a green screw, or possibly a green wire. Strip the wire ends with a wire stripper and fasten them together with a wire nut.

How do you wire a 230V outlet?

230 volt wiring requires 10-gauge or larger wire which, because of its size, is hard to bend. To ensure secure connections, its a good idea to crimp ring or fork lugs onto the ends of the wires and use these to connect the wires to the terminal screws. Procedure for Wiring a 230V Outlet

How do I wire a dual-voltage motor?

Read the nameplate on the motor and confirm that it is a dual-voltage motor. It will specify two voltages, one high and one low. The high voltage will be 200 volts or more; the low voltage will be 125 volts or less. Open the wiring box cover by removing the screws and verify there are four wires inside the box for wiring the motor.

How many volts does it take to wire a motor?

It usually shows how to wire the motor for common configurations such as 110 to 125 volts or 220 to 250 volts, and occasionally 208 volts. By following the wiring diagram, you can easily set the motor between voltages. Turn off power to the circuit at the circuit breaker before working on a motor.
