Which conductor is connected to the neutral point of a system meant to carry current under normal conditions?

The neutral conductor is specifically designed to be connected to the neutral point of an electrical system, and it serves several critical functions within that system. Primarily, the neutral conductor provides a return path for current in a circuit that balances the loads across the phase conductors. In a typical single-phase system, the current flows through the live conductor to the load and returns via the neutral conductor.

This arrangement is essential for the correct operation of electrical systems, ensuring that the voltage levels remain stable and balanced. It is also crucial for safety because it helps prevent the potential buildup of dangerous voltages in the system, which can occur if the circuit is unbalanced.

In contrast, the ground conductor is primarily a safety feature, designed to safely redirect any fault currents to the earth, thus preventing electric shock or fire hazards. Live and phase conductors are responsible for carrying the current from the source to the load but are not connected to the neutral point like the neutral conductor is. Thus, the neutral conductor is fundamental to the function and safety of electrical systems in normal operating conditions.
