  • Grounding neutral wire in household electrical distribution box

    Grounding neutral wire in household electrical distribution box

    White: The neutral wire, responsible for sending unused electricity back into the breaker panel. These two conductors serve fundamentally different safety functions, even though they may sometimes connect. In a typical residential electrical wiring, electric current flows through the “hot” wire to the load (an electrical appliance or device) and returns to the source (which is the distribution transformer in this case) through the neutral wire. (Exhibit 1) The hot and the neutral make the circuit “complete” to light. If grounding is necessary, we can connect the neutral wire to ground at the electricity supply stations. Ground wires, connected to the earth, act as a safety path for fault currents to prevent shocks.
