Q:

What is a three-phase electrical wiring diagram?

A:

A three-phase electrical wiring diagram is a clear, visual representation of a common method of power generation and distribution. Three-phase electrical wiring is the most common means of distributing alternating-current power on power grids world-wide.

A pictorial diagram is a simplified graphical representation of the components of the circuit, and a schematic diagram uses standardized symbols. Both types of diagrams depict the connections and parts of the circuit such as wires, power source and signal connections, but do not show the components' specific layout. Circuit diagrams are used for the design, construction and maintenance of electrical equipment. Though the symbols for electrical components have gone through many iterations over time, they are now largely standardized internationally.

    How do you wire a three-phase plug?

    A:

    First open the plug, and locate the inscriptions: 1, 2, 3 and 0 with a line on top of a T shape picture inside. Take the insulation wires, and strip about ¼ inch on the ends. Insert the wires according to the labeled slots: black goes in 1 or L1, red and blue in 2 or L2, white in 0 and green in the picture.

  • Q:

    How do you wire a three-phase motor?

    A:

    Wiring a three-phase motor begins with turning off the circuit that supplies power to the motor. Open the motor wiring box, and check for a nameplate with the wiring information. Connect all of the wiring with the right size, and number that coordinate with the conductors you want to use. You can either use the Wye wiring or Delta wiring for a three-phase motor.
