Last morning, on a 33 degree morning air I still decided to walk my dog. With this weather, I might need to wear a 2 pairs of pants, a hoodie with a long sleeve t shirt, a fleece ear warmer, and a pair of nice gloves. But I still have to consciously think about neglecting the temperature and how cold I am. I shifted my attention and I started thinking about the wide variety of topics I could blog and talk about.

While I was totally lost in my thoughts, to my surprise my puppy just started digging through my neighbor’s garbage bag and my dog found remains of their last night’s chicken dinner. So the struggle of telling my dog to drop everything has caused me trouble. I know my dog, he won’t just budge and he will not sacrifice the chicken bone he just started chewing on.

Now, with this in mind, we all know that the chicken bone is totally detrimental and dangerous for a dog. The splinters can come from the bone and it can potentially scrape my dog’s poor insides and it is no good. As a very reasonable owner of this pet, I have to give protection by restricting his access to this kind of scenarios. In just a short while, I realized that it kind of makes me a NEMA 1 protection for my dog. Except that I am not an enclosure, I am a human.

The NEMA 1 rating was defined as an electronics enclosure that is originally designed for the indoor use and it gives a degree of level of protection against the ingress of solid objects or potential contaminants (like the falling dirt.) The limited protection it provides also include the restriction of personnel for having access to harmful components.

There are different styles and some materials that are widely available for these kinds of enclosures. The metal, polycarbonate, and ABS has one thing in common: these materials can protect the electronics placed inside the enclosure from all the harm and debri. While it protects the user from the electronic.

Some companies also offers a full product line of NEMA 1 rated enclosure. As a matter of fact, the entire off-the-shelf product line can give protection to the equipment form the debris ingress and it also restricts the access of the personnel using the enclosure by giving protection to the electronics housed inside the enclosure.

Before adding vents, knockouts, and holes on the enclosure that can bring a potential effect on the rating, make sure that the applications are carefully considered when planning for the project. Once the specific rating is very important to the end use, conduct an independent testing of the final design of the product.
