Black Electrical WiresThese wires are often used as a switch leg that transfers power to switches and outlets in all circuits. Black wires are never used for a ground or neutral wire and are meant to be used as the power feed for a switch or an outlet. They are most commonly found in residential buildings.
What Color Is a Neutral Wire?
Is black positive or negative?

This happens when the hot and neutral wires get flipped around at an outlet, or upstream from an outlet. Reversed polarity creates a potential shock hazard, but it's usually an easy repair. Any $5 electrical tester will alert you to this condition, assuming you have a properly grounded three-prong outlet.Is black wire a line or load?
The color for the Line wire is usually black and the Load wire is usually red, black, or blue (less common).Which is live black or white?
US AC power circuit wiring color codesSee Table below. The protective ground is green or green with yellow stripe. The neutral is white, the hot (live or active) single phase wires are black , and red in the case of a second active. Three-phase lines are red, black, and blue.

The line side of an outlet is where you connect the incoming source power. The load side is where the power leaves the device (or electrical box) and travels down the circuit.Can Reverse polarity cause a fire?
Yes, if you accidentally reverse the polarity on an electrical outlet, the device you plug in to the receptacle isn't safe and could cause a short circuit, shock, or fire.Which wire is hot when both are black?
