What is a Gray Neutral Wire? The neutral wire (whether gray or white) is used to connect a conductive piece of metal (known as the neutral bus bar) to the electrical panel so that it can attract the current and distribute it throughout the facility.

What happens if you connect the wrong wires on a light fixture?
But here’s the catch: If you connect the circuit wires to the wrong terminals on an outlet, the outlet will still work but the polarity will be backward. When this happens, a lamp, for example, will have its bulb socket sleeve energized rather than the little tab inside the socket.
