If I require Nema 7 rated electrical components, do I specify Nema 4 or 4X for Ingress protection?
Nema 7 is typically specified for indoor service for hazardous locations classified as Class 1, Groups A, B, C or D, as defined in by the NEC. Nema 4 or 4X are enclosures specification for outdoor service and non-hazardous locations. If the application is outdoors (non-hazardous), then you must specify either Nema 4 or 4X.
