2.3 Specific components are incomplete in construction features or restricted in performance capabilities. Such components are intended for use only under limited conditions, such as certain temperatures not exceeding specified limits, and shall be used only under those specific conditions. 2.4 A component that is also intended to perform other functions such as overcurrent protection, ground- fault circuit-interruption, surge suppression, any other similar functions, or any combination thereof, shall comply additionally with the requirements of the applicable UL standard(s) that cover devices that provide those functions. 3 Units of Measurement 3.1 Values stated without parentheses are the requirement.

This may include covers, gaskets, boots, and similar protective means. That portion or portions of a device providing such protection may differ for the unmated and the fully connected conditions. 5.3 GASKET – A deformable material clamped between stationary faces to provide a degree of protection as specified in Table 9.1. This may include surfaces or features formed integrally from parts of the environmental enclosure made of deformable material. 5.4 SEALING MATERIAL – A pourable or extrudable substance, capable of some degree of hardening and bonding to substrates after application and used as a formed-in-place seal of joints or openings to reduce the likelihood of the passage of gases, vapors, or liquids. CONSTRUCTION 6 All Devices 6.1 When a receptacle or inlet is provided with or integrates into its design an outlet box, cabinet, junction box, or other portion of the environmental enclosure which includes a means for connection to a conduit, raceway, or other wiring system, in addition to the requirements in this supplement, such an outlet box, cabinet, junction box, or the like, shall comply with the applicable construction and performance requirements in UL 514A, UL 514C, or UL 50E, as appropriate.UL 498E 2020 pdf download.
