Three phase systems are extremely common in industrial and commercial settings. They can also be found in large residential complexes and appliances requiring a large amount of power. Although these systems may seem intimidating at first, a walkthrough on 3 phase wiring for dummies will help clarify the whole situation.


Three-phase electric power is a common method of alternating current electric power generation, transmission, and distribution. It is a type of polyphase system and is the most common method used by electrical grids worldwide to transfer power. It is also used to power large motors and other heavy loads.. A three-wire three-phase circuit is usually more economical than an equivalent two-wire ...

Figure 13. Three-phase, three-wire (three wattmeter method: set analyzer to three-phase, four-wire mode.) The three-wire, three-wattmeter connection has the advantages of indicating the power in each phase (not possible in the two-wattmeter connection) and phase to neutral voltages. Blondel’s Theorem: Number of Wattmeters Required


Most US commercial buildings use a 3 Phase 4 Wire 208Y/120V power arrangement because of its power density and flexibility. Compared to single phase, a 3 phase power arrangement provides 1.732 (the square root of 3) times more power with the same current and provides (7) power circuits.


The three-phase currents follow one another a third of a cycle apart. See Figure 4. Figure 4. If a voltmeter is used to test three-phase, full voltage will be found between any two of the three wires. A little over half voltage will be found from any one wire to ground. In Milwaukee, WEPCO used a 230-volt only, grounded, three-phase system.
