Outdoor Junction Boxes

Outdoor electrical junction boxes are designed to keep sensitive electrical connections protected and secure in any environment, even underground. Meeting a variety of NEMA and IP ratings ensures our waterproof junction boxes are robust and durable for outdoor use, but they can also be used for indoor applications. Outdoor junction boxes come in a variety of styles including options with hinged covers or knockouts, and options that can be wall mounted or pole mounted. With plastic, aluminum, and steel options available in a variety of sizes, it's easy to find the perfect electrical junction box solution. Read our guide on junction box types.

Looking for tips to help you choose the ideal junction box for your application? Find out more key info on junction boxes below.

Key Features and Applications of Outdoor Junction Boxes

Depending on its size, your facility might have dozens, hundreds, or even thousands of key electrical connections that need protection from environmental conditions. Numerous types of connections require junction boxes — from electrical wiring splices to electrical outlet boxes to switch boxes and beyond. Read our guide on junction box types to learn more about the many specific types of junction boxes on the market, including boxes for light fixtures, receptacles, and other applications. 

It’s critical to match the design features your application requires to a high-quality junction box that fulfills them. For example, a metal junction box is typically a must-have if your electrical connectors require RFI shielding and/or you’re using a metal-sheathed cable. Meanwhile, a plastic junction box is generally the standard choice for applications with non-metallic cable and cable clamps. However, the PVC boxes common in residential applications often aren’t up to the rigors of outdoor and industrial use, which makes materials like polycarbonate a better choice for heavy-duty applications.

Weather and hazard resistance is also a major factor for junction boxes used in demanding applications. Features such as weatherproof gaskets provide critical protection, and NEMA or IP ratings serve as useful guidelines for finding an enclosure with the right protective features. To learn more about choosing an enclosure with the right protective qualities, check out our guide to evaluating junction boxes.
