FAQ
What crimp tool is required for 4/0 AWG compression lugs?
Use a hydraulic or dieless compression crimp tool rated for 4/0 AWG copper lugs. Follow the tool manufacturer's die selection and compression index settings.
Can this lug be used in wet or corrosive environments?
The tin-plated finish provides corrosion resistance. For outdoor or wet locations, seal the termination with adhesive-lined heat shrink tubing after crimping.
Is this lug compatible with aluminum wire?
No. This lug is specified for copper cable only. Do not use with aluminum conductors.
