Know About Various Uses of the Junction Box

A junction box is necessary for almost all contemporary electrical systems. However, commercial electrical systems are usually subjected to harsher environments than residential systems. It’s crucial to specify junction box models for commercial applications that are made to a stricter standard and furnished with industrial-strength features.

What use does a junction box serve in modern business applications? How can a junction box be located that meets the requirements of your application? Following, we’ll discuss some of the most typical junction box business application cases. Additionally, we’ll showcase some of Polycase’s best enclosure options for safeguarding your wire in front of you!

What Purpose Does a Junction Box Serve in Business Applications?

The box shields the connections, which typically include weak spots like wire splices, from the elements and unintentional touch. Any location where two wires converge should be protected by a junction box, as you’ll see in our junction box guide.

Because of this, junction boxes are just as crucial in industrial settings as they are in residential ones. However, compared to residential boxes, commercial junction boxes may need to adhere to a far larger variety of requirements. Thankfully, Polycase provides a wide selection of enclosures that are excellently engineered for use in commercial electrical junction box applications.

Businesses must consider the particular needs of their use cases when selecting an enclosure to provide the appropriate level of protection. We’ll look at some of the crucial elements in the next sections, beginning with the crucial choice of the material to be used.

Plastic vs metal junction boxes

Enclosures for junction boxes can be built of plastic or metal (often aluminum or stainless steel). One of the first significant decisions to be made when defining an enclosure type for a commercial application is whether to use plastic or metallic junction boxes.

Which cable and conduit materials you use will determine your decision. A stainless steel junction box is typically required to provide grounding for metal-sheathed cable and metal conduit. The most common junction boxes for non-metallic cables are plastic ones. We’ll examine some of the best solutions for both metallic and plastic junction boxes that Polycase provides below.

Choosing the Correct Junction Box Size

The junction box’s actual size should be taken into consideration while making your decision. In our reference to junction box size, we go into great detail about this subject, including the recommended sizes for junction boxes according to the National Electrical Code. Because they frequently hold more connectors at once, commercial junction boxes are generally bigger than residential junction boxes.

In conclusion, you must take into account both the box volume and the box fill. Depending on how many conductors you require, use the weatherproof junction box sizing charts to determine the appropriate enclosure size. As putting cables in close physical proximity might cause interference in your system, wire spacing may also be an issue to take into account.
