What Are The 4 Wires In 3 Phase

By | January 12, 2023



In today’s world, it’s common to come across electrical systems that use three-phase power. Three-phase power is usually used to run large industrial applications or powering commercial buildings. But how does three-phase power work? One of the key components behind a three-phase power system is the four wires that make it all possible. Understanding these four wires and how they work together can help you to better understand the inner workings of a three-phase power system and what it takes to maintain one.

The four wires in a three-phase power system include the line wire, the neutral wire, the ground wire, and the equipment wire. All four wires are connected together to form a circuit that provides the power to operate a motor, motorized equipment, or other electrical components. When all four wires are connected properly, the current flows in one direction and the voltage remains consistent throughout the entire length of the circuit. This ensures that the power delivered to the equipment is the same, regardless of the length of the circuit.
