NEMA are rating standards used in North America to see what protection enclosures offer. In this conversion chart, NEMA standards are converted to the corresponding IP (ingress protection) rating. Note that NEMA ratings meet or exceed the IP rating. The reverse may not be assumed. Example: NEMA 2 may be IP11 or higher but IP11 may not be assumed to exceed a NEMA 2 rating.
