Nema Rating Quick-Reference Guide


We pulled together a quick-reference guide that lists the definitions of popular electrical enclosure NEMA ratings.

Electrical enclosures provide a barrier between the wire terminations/controls within the enclosure and the objects, environment, and personnel outside the enclosure. Different standards are required depending on the environment that the enclosure will inhabit. These standards are known as NEMA (National Electrical Manufacturers Association) ratings.

*** We strongly recommend that you confirm the enclosure rating & suggested application with your supplier prior to making your purchase and installation***
