32、hat are alsointended for securement to boxes with threaded entries, HUBs or fittings with internal female threads (e.g.conduit bodies, couplings). The requirements employ existing UL 514B requirements combined with newmarking requirements. The performance requirements are intended to be applied to t
33、he assembly of themale threaded fitting to an internally threaded mating product. The new markings ensure thatmanufacturers can properly identify the intended use of the externally threaded fittings and to provideinstallers and AHJs with the necessary information to easily determine the acceptabilit
