3 Phase 4 Wire Power Cable

The neutral is paired to each of the single phase load.

3 phase 4 wire power cable.

In the 4 wire cord and plug configuration the equipment grounding conductor now serves to do one of the jobs that the neutral was doing previously in the old 3 wire setup. It is also used to power large motors and other heavy loads. That is why even in the 3 wire cord configuration a return path in the form of the neutral wire was attached to the exposed metal.

A three wire three phase circuit is usually more economical than an equivalent two wire. Three phase systems are extremely common in industrial and commercial settings. Set your store to see local availability add to cart. This blog was originally posted on oct.

Although these systems may seem intimidating at first a walkthrough on 3 phase wiring for dummies will help clarify the whole situation. Different regions may use different voltages. Three phase plugs have five holes instead of the standard three alternating current means that the voltage in the wiring changes 50 to 60 times a minute. More options available.

Three phase electric power is a common method of alternating current electric power generation transmission and distribution. Since the voltage is not a constant the load that is attached to the power supply has to be able to deal with an alternating current. It is a type of polyphase system and is the most common method used by electrical grids worldwide to transfer power. The potential of the neutral point can be very well understood from the following figure.
