NEMA Safety Classification
NEMA (National Electrical Manufacturers’ Association) is a cooperative organization for the American electrical industry. The NEMA speci-
fications and testing methods are used by Underwriters Laboratories (UL) for testing and classification of enclosures. The table below gives
a comparison of the NEMA classification and the nearest corresponding IP rates.
