These are the same group of Stud Type Terminals, however, they have their own hinged individual protective covers, which are lifted up for connection and closed down after conductors are connected. This design makes them totally finger-safe, enhancing total safety. As an innovative solution, elmex has developed Stud Terminals OAT 2.5 and OAT 6. These terminals are provided with Hinged Covers within which the nuts remain captive. When the covers are opened up, carrying the captive nuts, the threaded bolts of the terminals are ready to receive the conductor prepared using Ring / Fork type lug crimped with the conductor. When the covers are closed the captive nut positions itself on the threaded bolt. The nuts are then tightened with a screw-driver, to establish the connections. The covers fully shroud the live metal parts and the insulated lug in the conductor clamping area, ensuring safety against electric shock hazards. Since the nuts are captive in the hinged covers, (i.e. No need to open them up), this type of construction facilitates quick and convenient way of making connections.
