What are the different applications of 3 wire cables in electrical installations?

Three-wire cables are commonly used in electrical installations for various applications, including power distribution, lighting circuits, and control systems. These cables typically consist of three conductors - a live wire, a neutral wire, and a ground wire. The live wire carries the current to the load, the neutral wire completes the circuit, and the ground wire provides a safe path for excess current to flow in case of a fault. This configuration allows for safe and efficient electrical connections in residential, commercial, and industrial settings.
