Electrical box come in many shapes and sizes. These boxes are used for outlets, switches, ceiling fixtures, junction boxes, and for keeping wires splices dry. Depending on the size and shape of the box, electrical boxes hold different amounts of wires. There are round, square, retangular, shallow, weatherproof, and extension boxes.

Electrical boxes come in plastic and metal varieties. Plastic boxes are non-conductive and are relatively inexpensive. They come in different styles that either nail on or are the cut-in variety. These cut-in boxes come equipped with wings that hold the box in place tightly against the drywall.

Metal or steel boxes are more durable than plastic boxes and some, like gangable boxes, can be joined to add more devices. These boxes are used in garages and basements where they are likely to be exposed and require more wear and tear traffic. Unlike plastic boxes that crack easily, metal boxes are built to last.
