Messing up the wires can lead to a non-functioning outlet at best, and a dangerous short circuit or electrocution at worst.

Hot Wire (Black Wire)

The hot wire, typically black (but sometimes red), carries the electrical current from the power source to the outlet. It's the wire that's "live" and potentially dangerous when the circuit is energized.

It's usually found connected to a brass-colored screw on the outlet receptacle. Handle with extreme caution, even when the power is off, as induced voltage can sometimes be present.

Neutral Wire (White Wire)

The neutral wire, always white, provides the return path for the electrical current, completing the circuit back to the power source.

It's typically connected to a silver-colored screw on the outlet receptacle. Although it's not considered "hot" under normal circumstances, it can still carry current and should be treated with respect.

Ground Wire (Bare Copper/Green Wire)

The ground wire, either bare copper or green, is a safety wire. It provides a path for stray electrical current to flow back to the ground in the event of a fault, such as a short circuit.

This helps to trip the circuit breaker, preventing electrical shock and reducing the risk of fire. The ground wire connects to the green grounding screw on the outlet and often to the metal electrical box itself. Its proper connection is vital for safety.

The Outlet (Standard Outlet/Electrical Outlet/Receptacle) Body

The outlet itself, also known as a receptacle, is the point of connection for your electrical devices. It features two or three slots (depending on whether it's a grounded outlet) and screw terminals for connecting the wires.

The screw terminals are color-coded to match the wires they're intended to connect to: brass for hot, silver for neutral, and green for ground.

Outlets also have current and voltage ratings, usually printed on the back. Standard household outlets are typically rated for 15 amps or 20 amps at 125 volts. Make sure the outlet you're using is appropriate for the circuit it's connected to.
