The electrical boxes in your home are essential parts of the electrical system. However, many DIYers are perplexed by the vast range of packages available.
All of the most commonly used electric boxes for domestic wiring projects are available at home centers and big hardware stores. Understanding the differences is essential for purchasing the correct boxes. There are several factors to consider, including materials, shape, and size.
Metal Or Plastic Electrical Boxes
The majority of electrical boxes are made of metal or plastic. Steel is used in metal boxes, while PVC or fiberglass is used in plastic boxes. Aluminum is commonly used to make weatherproof metal boxes for outdoor use.
A metal box is required if you’re using metal conduit to run wiring to the electrical box, both to anchor the line and because the conduit and metal box system can be used to ground the system. If you’re using a non-metallic cable, such as Type NM-B (non-metallic sheathed cable), you can use either plastic or metal boxes as long as the cable is adequately secured with a cable clamp.
Modern NM-B cable systems typically include a ground wire within the cable, which means the box is not incorporated into the grounding system. You can contact professional packing manufacturers, who can provide you with various storing options to store any of your wirings.

Rectangular Boxes
These are used to contain household switches and electrical outlets in the same way that ordinary rectangular boxes do, but they are enlarged so that two, three, or four devices can be put side-by-side. These come in a variety of “new work” and “old work” styles, some having built-in cable clamps, just like other boxes.
Standard rectangular boxes with a “gangable” construction that allows the sides to be removed and the boxes to be connected together to form larger containers can achieve the same effect.
2,3 and 4 Gang Boxes
These are used to contain household switches and electrical outlets the same way that ordinary rectangular boxes do, but they are enlarged so that two, three, or four devices can be put side-by-side. These also come in various “new work” and “old work” styles, some having built-in cable clamps, just like other boxes.
Standard rectangular boxes with a “gangable” construction that allows the sides to be removed and the boxes to be connected to form larger containers can achieve the same effect. You might require various equipment for this purpose, which include headers, tiny wires, etc.

Round Pan Electrical Boxes
The electric meter box dimensions of round pan boxes, also known as “pancakes,” are usually only 1/2 inch or 3/4 inch deep. They’re most typically utilized for light fixtures that are installed on the ceiling or wall and weigh less than 50 pounds. Ceiling fans can be mounted in some types of specifically approved metal pan boxes, although not all pan boxes can be used for this purpose.
It’s critical that the fixture wires are properly connected and installed inside the round pan box. These are small electrical boxes that can only accommodate two or three electrical connections.
If there are additional wire connections to be made, a full-sized octagon or round electrical box with more volume would be required. The electrical box’s safe fill capacity should never be exceeded by the amount of cables in it.
Octagonal Electrical Boxes
The usual box for ceiling- or wall-mounted light fixtures weighing up to 50 pounds is the octagon or regular-size round box, which is 1 1/2 to 3 inches deep. They can be utilized as junction boxes and provide substantially more wire space than shallow round pan boxes.
Metal boxes are ideal for use with metal conduit in surface-mounted systems. In existing or “old work” applications, round plastic boxes sometimes feature “ears” for attachment to the wall or ceiling surface. Instead of making a huge hole in the drywall to fasten the box to the framing, these allow you to secure the box to the drywall (or other surface material).
Ceiling Fan Electric Boxes
Ceiling fan boxes are available in a variety of styles and sizes. These types of boxes are usually 1/2-inch deep “pancake” versions. They also come in normal 2 1/8-inch deep boxes. They are often round, although they can also be octagonal.
For ceiling fan mounting, ceiling fan boxes must be UL-listed and labelled “For Use With Ceiling Fans.” Do not use regular round or octagonal boxes. To endure the dynamic loads of a revolving fan, ceiling fan boxes require specific fastening.
Depending on the installation method, most ceiling fan boxes can support fans or light fixtures up to 75 pounds. Boxes can be attached to adjustable brace spanning across the ceiling joists or directly (with four screws) to a ceiling joist or wood blocking.
4- Inch Square Electrical Boxes
Square boxes are available in typical depths of 1 1/4 to 2 1/8 inches, but their square corners provide extra internal space, allowing for more wires and connectors. As a result, 4-inch square boxes are frequently used to run several conductors in multiple directions.
They’re also known as junction boxes, and when paired with the appropriate cover plates, they can be put in ceilings or walls to support lighting fixtures or to house switches or receptacles.
Junction Electrical Boxes
A junction box is a word used to describe any common electrical box used to cover wire splices, rather than a specific type of box. The traditional junction box is a 4-inch square box, which provides plenty of room for establishing wire connections with several wires or cables, however other types of boxes can also be utilized.
Outdoor Electrical Boxes
These are used to contain household switches and electrical outlets in the same way that ordinary rectangular boxes do, but they are enlarged so that two, three, or four devices can be put side-by-side.

Outdoor Electrical Boxes
Weatherproof outdoor boxes are weatherproof enclosures that can be mounted to outside walls, roof overhangs, decks, and other buildings. Outdoor receptacles (outlets) and light fixtures are installed with them. Depending on the application, outdoor boxes must have an exterior cover or fixture suited for damp or wet regions.
Plastic outdoor boxes are often composed of high-impact PVC, whereas metal outdoor boxes are built of aluminium rather than steel.
