Junction boxes are an essential part of the electrical wiring systems for homes and buildings alike.
The purpose of these boxes, which are often made from metal or plastic, is to house and safely protect
a structure's electrical connections.
This sort of electrical casing typically comes in two sizes. Junction boxes that measure 2 inches x 3
inches, with a depth of 2.5 inches, generally contain three wires. Boxes that measure 2 inches x 3 inches
and have a depth of 3.5 inches are made for five or more wires.
The electrical wires these boxes protect are known as hot (black), white (neutral), and grounding
(green or copper). You may also see some other wire colors, which are used for secondary functions and lighting
