There are two ways to classify electrical enclosures, IP and NEMA. The first technique is based on the enclosure’s degree of security from external variables such as dust, moisture, and pollutants.
They are employed in diverse contexts and use slightly different evaluation techniques, even if they accomplish comparable goals.

![](https://kdmfab.com/wp-content/uploads/2024/03/Comparing-IP-Enclosure-Protection-Ratings-to-NEMA-Ratings-A-Closer-Look-1.png)
Ratings for NEMA
- NEMA founded in the US.
- NEMA ratings address more environmental factors than only solid and liquid resistance.
- A number code, such NEMA 1, NEMA 4X, etc., that is used to designate NEMA ratings indicates an environmental protection characteristic.
Ratings for IP
- IP is a global standards group founded by IEC.
- The protection of electrical enclosures from solids and water is categorized using IP ratings.
- Whereas the second depicts liquid security, the first shows solid security.
Comparison
- Both ratings are useful tools
- Protection from liquids and solids
- A wider range of environmental factors are frequently taken into account when grading NEMA products.
Ratings for IP Enclosure Protection

The Defense Against Solid Objects
- 0-No defense.
- 1-Resistance to condensation, or the vertical descent of the water droplets, is the first.
- 2-Protection against water droplets that could hit the ground at a 15-degree angle.
- 3-Protection from water that spills from vertical surfaces at a sixty-degree angle.
- 4-A blockage to stop water leaks coming from all sides.
- 5-Impermeability to low-pressure aimed in either direction.
