Bootlace ferrule insulated, copper conductor with polypropylene insulation, model EB933975675#

Insulated bootlace ferrule designed for terminating stranded copper conductors. This ferrule combines a tin-plated copper tube for a reliable crimp connection with a polypropylene insulating sleeve that prevents stray contact and offers mechanical strain relief. It is intended for use where a secure, low-resistance termination is required for electrical panel wiring, terminal blocks and device connections in industrial and domestic installations.

Advantages

The polypropylene insulation provides consistent electrical isolation and resists abrasion while the copper tube ensures stable conductivity and corrosion resistance after crimping. The design yields compact, uniform terminations that reduce the risk of stray strands and improve screw-terminal clamping. The insulated sleeve also simplifies identification and reduces the likelihood of short circuits during installation or maintenance.

Suitable for

• Terminating stranded copper conductors for circuit breakers and terminal blocks
• Electrical panel wiring and junction connections
• Signal and control wiring in industrial equipment
• Domestic electrical installations where secure screw connections are required

Key specifications

• Conductor material: copper tube for crimp termination
• Insulation material: polypropylene sleeve
• Intended conductor type: stranded copper conductors
• Function: provides electrical isolation, strain relief and improved screw-terminal contact
• Typical applications: panel wiring, terminal blocks, device connections

How to use

Strip the conductor to the appropriate length, insert the stranded copper conductor fully into the ferrule tube and crimp using a suitable insulated ferrule crimping tool sized for the ferrule and conductor. Ensure the crimp is square and firm to avoid loose strands. After crimping, insert the ferrule into the terminal or screw connection and tighten to the manufacturer’s recommended torque. Verify mechanical stability and electrical continuity after installation.

Usage recommendations

Use the ferrule with the correctly sized crimping die for the conductor cross-section. Avoid reusing ferrules after deformation; select the proper ferrule size for the conductor to maintain low contact resistance and reliable mechanical performance.
