Blue 14 AWG Wire Ferrule - 8mm Length - 25 PackWire fraying can quickly become a problem when dealing with IEC (European)-style terminal blocks. As the wire frays, the connection becomes weaker, and the problem will need to be addressed. But all that can be prevented. How? By utilizing wire ferrules. Wire ferrules are a type of terminal that prevents wire fraying. It covers the stranded wire and creates a solid, connected piece. In a sense, wire ferrules make stranded wire behave like solid wire. This is important, especially when working with IEC terminal blocks.How are wire ferrules properly used? The first step is to strip the wire to the correct length. Now slide the ferrule over the exposed wire. Make sure that the nylon casing butts up to the wire insulation. Once set, crimp using the proper tool. Using the proper tool is important, as, without the proper pressure, the wire may not create a solid connection. Proper crimping pressure and technique are key to ensuring continued performance. Once properly crimped, users can add heat shrink for added protection if they choose. Features:Prevent strand separation while minimizing strand breakageInsulated ferrules provide additional electrical insulationIncrease connection reliability when terminating stranded wire in terminal blocksSpecifications:Package Size: 25Wire Size (AWG): 14Insulation Color: BlueFerrule Length: 8mm (0.31 in.)Stripping Length: 10mm (0.39 in.)
