What do the three wires in a standard electrical outlet represent?

The three wires in a standard electrical outlet represent hot, neutral, and ground. The hot wire carries the electrical current from the power source to the outlet and is typically insulated in black or red. The neutral wire completes the circuit by bringing current away from the outlet back to the power source and is usually insulated in white. The ground wire is a safety feature designed to protect against electrical faults by providing a path for electricity to safely dissipate into the ground, typically insulated in green or bare.

Understanding the function of each wire is essential for proper wiring and electrical safety. The hot wire delivers power, the neutral wire provides a return path, and the ground wire ensures that the system is safe from electrical shocks or surges. This structure of wiring is standard for most household electrical systems, ensuring consistent and safe operation of electrical devices.
