Copper Crimp Lug · 2/0 AWG · 5/16 in Stud · Colour-Coded Compression Lug · ITC Electrical 39C2/0-516
Copper compression lug for 2/0 AWG conductor termination with a 5/16 in stud hole. Commonly used for panel, equipment, and power distribution terminations where a crimped copper lug is required.
What this product is for
This copper crimp lug is used to terminate 2/0 AWG copper conductors onto a 5/16 in stud connection. It is suited to switchgear, panels, distribution equipment, and other power terminations that require a compression-style lug.
Use for
- Terminating 2/0 AWG copper conductors
- Bolting onto 5/16 in hardware
- Panelboards, control equipment, and distribution connections
- Service and feeder conductor terminations where the conductor and tooling match the lug specification
Avoid for
- Conductors smaller or larger than 2/0 AWG
- Stud sizes other than 5/16 in
- Applications where an aluminium lug or bi-metal lug is required
- Installations without the correct crimp die and approved installation method
Best for
Best for electricians and maintenance teams needing a straightforward copper compression lug for 2/0 AWG terminations on equipment with 5/16 in studs. The colour-coded format helps with lug and die selection where matching tooling systems are used.
Installed in
Typically installed in electrical rooms, industrial equipment, commercial distribution assemblies, motor connections, and retrofit panel work. Final suitability depends on conductor type, crimp tooling, and local code requirements.
Why this product exists
It provides a secure mechanical and electrical termination between a large copper conductor and a stud-mounted connection point. Compression lugs are commonly chosen where a compact, permanent termination is preferred over mechanical set-screw connectors.
Compared with similar products
Compared with mechanical lugs, a compression lug typically provides a more compact finished termination but requires the correct crimp tool and die. Compared with larger stud-hole lugs, this version fits 5/16 in hardware, which matters when space and pad drilling are fixed.
