FAQ
What crimp tool is required for this 3/0 AWG lug?
Use a hydraulic or dieless compression crimp tool rated for 3/0 AWG copper lugs. Proper tool selection ensures uniform compression and gas-tight termination.
Can this lug be used outdoors?
This bare copper lug is intended for controlled indoor or protected environments. For outdoor or corrosive environments, specify a tin-plated lug or seal the termination with adhesive-lined heat shrink.
Is this lug compatible with aluminum wire?
No. This lug is designed for copper cable only. Do not use with aluminum conductors.
