The four wires in the distribution box are connected to three live wires

In a three-phase 4 wire system, there are three live wires, usually colored red, yellow, and blue, and one neutral wire, usually colored black or white. Each live wire carries a phase of the electrical current, and the neutral wire acts as a return path for the unbalanced. The three-phase, four-wire system is the foundation of modern electrical distribution, powering the infrastructure of cities and industry. Unlike the simpler single-phase power delivered to most homes, this configuration handles significantly larger power demands with superior efficiency. This. Three wires are taken from the phases and the fourth wire (i. The 3 phase 4 wire system is generally used for the secondary distribution. The three-phase distribution board is used to distribute power to the three-phase loads and circuits such as three-phase motors, three-phase machinery, three-phase to single-phase distribution boards, etc. Star winding is so important for getting neutral point so neutral point is important for equipment utilization.
