314.3 exception 1?
Expert:  ProGrade replied 5 months ago.
314.3 exception 1 would apply if grounding bushings are employed or if there is a metal grounding provision integrated into the plastic box...much easier & safer to use a metal box unless you have other considerations and want to employ the grounding bushings
