NEMA Enclosures

 

What is NEMA?

The National Electrical Manufacturer Association (NEMA) sets technical standards and guidelines for the manufacture of safe electrical products, including enclosures. NEMA’s standard rating system defines the types of environments in which an electrical enclosure can be used and the enclosures’ ability to maintain effectiveness in said environments.

NEMA standards benefit both the manufacturer and the user by:

• Improving safety
• Improving economics
• Improving communication between manufacturer and purchaser
• Assisting purchaser in selecting and obtaining the proper product for a particular need

 What are NEMA ratings?

While NEMA sets standards for a broad range of electrical products, the term “NEMA ratings” is commonly used to refer to a specific standard for electrical enclosures. NEMA standard ICS 6 categorizes enclosure types according to their ability to protect against damage due to substances such as water, dust and corrosive chemicals. A new review of these standards is published every five years.

How are enclosures certified under the NEMA rating system?

NEMA does not test products. Manufacturer’s compliance with the NEMA standards is entirely voluntary. Should they wish to adhere to the standards, manufacturers test their own products according to the enclosure standards defined and published by NEMA.
