The utility of standards provide the benchmarking of the system which is intended to be designed. They exhibit the choices to system designers for the selection of product by comparing the specifications.
NEMA- 4X indicates the presence of corrosive atmosphere wind-blown dust in addition to rain-directed water. It completely implies the hazardous or catastrophic area. Besides these, NEMA-4 is applicable for indoor and outdoor areas.
NEMA-12 exhibits its applications at site but non-hazardous area while & NEMA-13 finds its application at site only.
