When dealing with IEC (European)-style terminal blocks, preventing wire fraying is crucial for maintaining strong connections. Wire ferrules serve as an effective solution, encapsulating stranded wire to form a stable and solid connection, which mimics the behavior of solid wire. This is especially important when interfacing with IEC terminal blocks.

To use wire ferrules correctly: First, strip the wire to the appropriate length. Then, slide the ferrule onto the exposed wire, ensuring the nylon casing sits against the wire insulation. Use a proper crimping tool; achieving the right pressure is essential to establish a solid connection. After crimping, users might opt to add heat shrink for additional protection.
