There are several electrical devices and equipment installed outdoors and most of the people do not even notice. From the junction boxes to electricity transformers, all of these are protected by an enclosure. For design engineers, they are fully knowledgeable about how much is happening in the background. Engineers know that our electrical devices are what keeps and maintains our comfortable lifestyle. However, to protect these devices, the engineer should choose the proper electrical enclosure.
With this in mind, which is the NEMA rated electronics enclosure cabinets are considered weatherproof?
Commonly, these are the NEMA rating ideal for weatherproof applications:
- NEMA 3 and its subsets
- NEMA 4 and NEMA 4X
- NEMA 12
But for this article, we will discuss NEMA 3 and its subset, NEMA 3R.
