Wire Vs. Cable
While the terms wire and cable are often used interchangeably, a wire is one electrical conductor and cable is multiple conductors, or a group of wires, encased in sheathing.
Wire Labeling
The information printed on the sides of wire indicates its THHN/THWN, material, max voltage rating and gauge.
Wire Colors
A wire’s color tells you the purpose of the wire. Typically, white wires are neutral wires, green or bare wires are ground wires and any other color is a hot wire that carries an electrical current.
Types of Electrical Cable
Different types of electrical cables each have their own specific purposes and applications. Below are common cables you may use in your projects:
