Junction box enclosures are often composed of aluminum or stainless steel, although they can also be made of plastic (usually poly carbonate or ABS). 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.
The cable and conduit materials you use will determine your decision. With metal-sheathed cable and metal conduit, a stainless steel junction box is often required to provide grounding. 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 Poly case provides below.
Uses in Industry for Junction Boxes
Commercial electrical systems frequently employ junction boxes, and large systems may require hundreds or even thousands of junction boxes. The precise application requirements will determine the response to that query. Let’s examine several typical electrical junction box applications and how the unique dangers of each area affect the kind of box you’ll require.
Retail and Office
The least demanding uses for junction boxes are often in commercial offices and retail buildings. These applications nonetheless require fundamental security against unwanted entry and unintentional contact, as well as junction boxes with a larger interior than those found in typical residential boxes.
Storage facilities and distribution hubs
Although most warehouses and distribution hubs don’t experience extreme weather, they nonetheless require demanding applications. To run lighting systems, climate control, and other necessary equipment, these buildings frequently consume a lot of electricity.
Production Facilities
Electrical systems must be very dependable and secure in the manufacturing sector. High voltage demands are frequently dispersed across several branch circuits using exceedingly intricate systems. Hazards like flying debris and splashing water are also common in industrial plants.
These elements can combine to create a very difficult collection of circumstances. Weatherproof junction box rated NEMA 12 is a viable option for less demanding production applications. On the other side, more risky locations could require exterior-rated boxes like NEMA 3R or NEMA 4X enclosures. And last, a UL 94 flame certification is frequently needed in the industrial industry.
