0558009294 - ESAB 4/0 Cable Ferrule Kit (5-Pack)

ESAB Non-Insulated Ferrule for 4/0 Cable (Pack of 5)

The ESAB 0558009294 is a pack of five non-insulated ferrules designed specifically for terminating 4/0 AWG welding cables. In industrial and MRO environments, maintaining the integrity of high-amperage power connections is critical for both safety and equipment performance. These ferrules serve as a vital component in cable assembly, acting as a sleeve that encases the stripped end of a stranded cable. By holding the fine copper strands together, the ferrule creates a solid, unified mass that can be easily inserted into mechanical lugs, terminal blocks, or screw-type connectors without the risk of individual strands splaying or breaking off.

Manufactured to ESAB's high standards, these ferrules are essential for ensuring low-resistance connections. When a stranded cable is tightened down directly by a set screw without a ferrule, the rotating action of the screw can sever fine strands, reducing the effective cross-sectional area of the cable and creating hot spots. Using this 4/0 ferrule mitigates that risk entirely. The non-insulated design ensures that the ferrule does not interfere with the electrical contact inside the connector, while still providing the mechanical benefits of strand containment. This product is supplied in a pack of five, making it suitable for repairing multiple leads or fabricating a complete set of welding cables.

These components are particularly useful in heavy-duty welding setups, power distribution panels, and grounding applications where 4/0 cable is standard. They ensure that the full current-carrying capacity of the cable is utilized by maintaining 100% strand contact at the termination point. For maintenance teams and fabricators, keeping these ferrules on hand ensures that cable repairs meet professional standards for durability and electrical efficiency.
