Ferrules ensure reliable electrical connections when terminating stranded flexible wires in terminal blocks, circuit breakers or other control devices. They prevent fraying and breaking of individual wire strands. Ferrules are available uninsulated and insulated with color coded plastic sleeves for single or dual wire applications. Insulated ferrules also support the conductor, preventing breakage due to bending, wire stress and vibration.
Ferrules are the preferred alternative to twisting wire strands or tinning the wire end. European Electrical Standards such as EN60204-1, and VDE 0611, specify that "Means of retaining conductor strands shall be provided when terminating conductors at devices or terminals which are not equipped with this facility. Solder shall not be used for this purpose." Conductors with tinned ends should not be terminated in compression clamps because solder will cold flow under pressure and eventually result in poor or loose connections.
