If you work with electrical equipment outdoors, you’ve probably come across the term “NEMA 3” more than once. It’s one of the most popular enclosure ratings in the industry — but with subtypes like 3R, 3S, and 3X in the mix, it’s easy to feel lost. Here’s a straightforward guide to what NEMA 3 enclosures do, how they’re tested, and what sets each subtype apart. What Does NEMA 3 Mean?

Enclosures typically need a minimum of one cutout for a power cable and often many other modifications, which can include holes, cutouts, tappings, gaskets, pre-assembly, and finishing. For many design engineers, specifying enclosure modifications is the final step in the design cycle, with time-to-market pressure…
