IP Rating and NEMA Protection Explained

IP ratings are used to quantify the amount of protection the enclosure offers. Instead of saying water resistant, the IP code can tell us exactly how much water or dust particles a particular device is protected against. Hence an IP rating of IP67 means that the enclosure is dust proof and water resistant up to 1 meter of liquid submersion.

NEMA to IP Conversion

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.
