Where the CTL4-8 Crimp Lug Is Used

A compression crimp lug terminates a single conductor end to a bolted connection point — the conductor is inserted into the barrel and a compression crimp tool closes the barrel around the conductor, making a permanent, mechanically secure, low-resistance termination. The tongue of the lug is then bolted to the connection point — a terminal block, earth bar, busbar, equipment stud, or similar — using an M8 bolt through the 8mm stud hole.

The CTL4-8 is sized for 4mm² conductor — the cable size used for higher-current circuits in Australian residential and commercial wiring including air conditioning circuits, stove and oven sub-circuits, and other dedicated appliance circuits. The 8mm stud hole suits M8 hardware — used on larger terminal blocks, heavy duty earth bars, switchboard busbars, and equipment connection points where a robust mechanical fixing is required. The tinned copper construction combines the excellent conductivity of annealed copper with a tin electroplated surface that resists oxidation and maintains a clean, low-resistance contact at the bolted joint over the service life of the installation.

Crimp lugs in this range are available across a wide range of cable sizes and stud hole combinations — covering the full range of conductor sizes and connection hardware used in Australian electrical installations.

Q: What is the difference between a crimp lug and a crimp link?
A: A crimp lug (CTL4-8) terminates a single conductor to a bolted connection point — it has one barrel end for the conductor and one tongue with a stud hole for the bolt. A crimp link joins two conductor ends together — it has an open barrel at both ends. Use a crimp lug for conductor-to-terminal connections; use a crimp link for conductor-to-conductor joints.

Q: What stud or bolt size suits the CTL4-8?
A: The CTL4-8 has an 8mm stud hole, suited to M8 bolts and studs — used on larger terminal blocks, heavy duty earth bars, and switchboard busbars.

Q: Is the CTL4-8 sold individually or in a bag?
A: The CTL4-8 is sold individually.
