What is NEMA and IP?

Are NEMA enclosure classes the same as IP?

Although each system uses a very different numbering scheme, some of the IP and NEMA classes are reciprocal.

Which of NEMA and IP should I use?

It depends where you are. In Europe and Asia, IP classes are used to determine sealing protection. In North America, NEMA is more common. However, more and more companies are using IP classes as standard.
