What Are The 4 Types Of Electrical Boxes?

There are four types of electrical boxes: recessed, surface mount, round, and oval. Recessed boxes are generally less intrusive than surface mounts but can block access to future equipment. 

Different boxes serve different purposes. You may need one for outlets and switches, while another is intended for hanging lights. Some are designed to withstand weather conditions, while others are specifically for outdoor use. 

Depending on your needs, you should look for the type that is most suitable for the location. In addition to your budget and architectural style, you should consider what specific features the electrical box should have. 

Metal boxes are generally larger than their counterparts, so you need to choose the appropriate one for your needs. They are useful for hubs where multiple cables meet.

What Are Electrical Boxes?

An electrical box is an enclosure that contains all the wires. There are a variety of shapes and sizes, but the fundamental purpose of electrical boxes is to provide adequate electrical supply. 

Single-light switches fit into rectangular electrical boxes known as single-gang or one-gang. Two-gang, or gangable, boxes can store more than three devices. Many manufacturers make several types, so it’s worth looking in manufacturers’ catalogues for specifics. 

Another common type is the octagon box, which connects light fixtures. They’re characterized by cover plates that protect the conductors. These boxes are also called junction boxes. 

Round pan boxes are generally only 1/2″ to 3/4″ deep and are typically used with ceiling or wall-mounted fixtures weighing more than 50 pounds. Depending on the location of the device, junction boxes can be used to separate circuits and connect multiple wires.

What Are the 4 Types of Electrical Boxes?

There are four different types of electrical boxes. They are PVC, Metal, Square, and Triple Gang. These types of boxes are all used for different types of wires, such as wall outlets.

  • PVC/ Plastic Electrical Box

PVC electrical boxes are made from polyvinyl chloride (PVC). They have hand-close fasteners, a moulded mounting foot, built-in gridlines, and hinged or flat cover options. These electrical boxes are CSA approved, UL listed, and NEMA certified. The materials they are made of are high-quality, ensuring that you will get a long-lasting product. These boxes are highly durable and can handle high amounts of pressure and heat. Plastic electrical boxes are lightweight and inexpensive. They are easy to install, too. 

  • Metal Electrical Box

When you are installing new circuits or replacing an old one, you may want to use a durable metal electrical box. These boxes have a deep enough interior to accommodate the wiring and include drywall gripper arms. These boxes are designed to be UL listed, which ensures the safety of your electrical devices and supplies. This product is made of high-quality materials for years of dependable service. It also withstands the high heat and pressure of an electrical box. To ensure safety, it is essential to ground metal electrical boxes. By doing this, you are ensuring that your wiring is grounded and is not exposed to dangerous electric currents. 

  • Square Electrical Box

An electrical box is a metal enclosure used to contain electric devices. The types of electrical boxes are square, portable, weatherproof, and fixed. Some types are specialized for outdoor and weatherproof installations. It is important to choose the right type for the project that you’re working on since electrical boxes must protect your wires from damaging neighbouring materials. 

  • Rectangular Electrical Box

Rectangular boxes are typically mounted vertically in walls and are suitable for a single switch or duplex receptacle. They are typically 2″ x 3″ and can vary in depth from 1.5″ to 3.5″. Some rectangular boxes are gangable. You can mount multiple duplex receptacles and switches in the same box. However, you can also install single switches in these types.
