When installing cables, environmental factors have to be taken into consideration, such as humidity and rain. Youtube channel Summit Electric Supply demonstrates the installation of the Mighty Seal jacketed MC cable connector.
Cable connectors seals have multiple parts. They have a corrosion-resistant zinc die-cast body, an internal cable armor locking device, a zinc die-cast compression nut, a washer, a water-tight neoprene gland, a water-tight knock-out gasket, a reversible zinc-serrated lock-nut, and an insulated throat.
When installing the cable connector, it’s important to consider the length of your conductor, which will go into your enclosure. Next, the pvc jacket will have to be stripped from the cable and expose 7/8ths of the armor.
Next is installing the cable connector itself. First, slip on the compression nut, washer, neoprene gland (has to be on top of the pvc jacket), the zinc die-cast body, seal the compression nut by turning it on tight (with an additional 1 and ΒΌ turn with a wrench), remove the zinc-serrated die-cast lock-nut, insert the cable into the enclosure (making sure the knock-out gasket is on the outside), and attach the lock-nut and screw it on (with an additional quarter turn via a tool).
