Most Frequently Asked Questions about NEMA 1 Electronics Enclosure

One of the fastest and quickest ways to be able to identify if an electronic box will certainly meet your company’s needs is to identify its NEMA rating. The rating system is designed to help the companies determine which enclosure should they get for a certain engineering application. The rating will also give the user the vital information about its protective performance – but it is really important to have a firm and full understanding of the NEMA ratings before they companies can choose one.

In this article we will look at the most frequently asked questions about NEMA 1 Electronics Enclosure.

What does NEMA rating mean?

NEMA ratings is an established system of electrical enclosure ratings set by National Electrical Manufacturers Association to help the companies identify different qualities of each electronics enclosure. This rating shows how different types of NEMA ratings can give protection from certain environmental hazards such as dirt, dust, and water ingress. Included in this rating is also the corrosion protection.

For companies or design engineers to learn about what these different NEMA ratings mean, they should check out the official NEMA ratings website and chart to have a full understanding of how the different level of NEMA ratings can give certain protection it indicates. In line with this, make sure that all the guidelines have been read carefully because unlike IP ratings, they do not come with numerical orders that determine the rate of protection each enclosure can give.

What does NEMA 1 mean?

When it comes to varying degrees of protection NEMA enclosure gives, NEMA 1 offers the most basic level of protection. This type of enclosure is used to protect equipment from ingress of small amounts of falling dirt. NEMA 1 also gives protection for employees from having accidental contact because there might be live components inside the enclosure. With this in mind, NEMA 1 electrical box rating provide a good amount of protection from liquid ingress that can come from hose-directed or splashing water.

Where can I use NEMA 1 Electrical Boxes?

Companies use NEMA 1 enclosure in applications where they need the most basic level of protection for their equipment. Basically, almost all types of electronics equipment can be housed inside the NEMA 1 enclosure. For example, you can put in an industrial control panels inside the electrical box or controls to different security systems.

In a typical scenario, you will be able to see NEMA 1 enclosure for engineering applications which does not need protection against hazardous environmental hazards, but they will be needing the most basic level of protection for their equipment.

Is NEMA 1 Electrical Enclosures Applicable for Outdoor Applications?

NEMA 1 electrical boxes are recommended for indoor engineering applications. NEMA 1 can be sufficient in some outdoor environments, but if a company needs a level of protection for their equipment once used outdoors, the best idea is to use the enclosure rating that is primarily designed for outdoor use. Such as NEMA 3, NEMA 4 or even NEMA 6 electronics enclosure.

What is the key difference between NEMA 12 and NEMA 1 electrical enclosure?

NEMA 12 rated electrical boxes offer a much higher degree of protection compare to NEMA 1 enclosure. Keep in mind that NEMA 1 electronics enclosure can only offer so much as long as you need protection for your equipment for any indoor type of application.
