3M 30045 Compression Lug 4/0 AWG Pack 10
These 3M 30045 lugs connect 4/0 AWG stranded copper conductors in solar and electrical installations. Each pack contains ten copper lugs rated for up to 35 kV and listed by UL and CSA. The straight tongue fits a 1/2 in stud with a 1 in width and uses die code 15 for crimping.
Install with standard crimp tooling using die code
Crimp the barrel with a compatible compression tool matched to die code 15 for a secure termination. The barrel inside diameter is .54 in and outside diameter is .68 in. No inspection hole is present so visual verification of wire insertion must occur before crimping. Ensure the conductor is copper; the lug is not rated for aluminium.
Verify conductor size stud size
Confirm the existing wire is 4/0 AWG stranded copper and the mounting stud measures 1/2 in. The system voltage must not exceed 35 kV. The single hole pattern requires a matching flat mounting surface. RoHS compliance is confirmed for regulated projects.
