Anywhere electrical lines come together, there’s an electrocution risk to people or animals who could come into contact with live wires. These junctions are also vulnerable to dirt and moisture, which can compromise the electrical system and even create a fire hazard. Junction boxes are essential pieces of equipment used by electricians who shield these connections from debris and minimize the risk of fires and injuries.

What Is a Junction Box?

A junction box is an insulated container with built-in connectors and terminals and small openings for wires to pass through. These boxes are made out of plastic or another non-conductive material, which reduces the risk of anyone coming into contact with a live wire.

In residential electrical systems, most boxes are just a few inches wide, but commercial and industrial applications may require large, custom-built boxes designed to accommodate a variety of wires and connection types.

Where Are They Used?

Junction boxes can be found throughout any electrical system, including in homes, offices, storm shelters, and even vehicles. Not only do these boxes protect your wires, but they also help keep complex systems organized into units, which makes repairs and upgrades significantly easier.

In older homes that have undergone changes or expansion, it’s not uncommon to see junction boxes that are too full. Over the years, electricians may have routed new wiring through an existing box until it can’t handle anything else. 

How Do You Choose a Junction Box?

The right junction box for any particular project depends on the amount of power going through the connection, the types of wire used, and the protection rating you need. For instance, some boxes are designed for indoor use, while waterproof units can be used to power security lights and other outdoor fixtures. If you’re installing a landscaping system, you’ll want junction boxes designed to withstand anything the elements can throw at you.
