FAQ
What crimping tool is required for 250 MCM compression lugs?
Use a hydraulic or mechanical crimping tool rated for 250 MCM copper conductors with the appropriate die size. Follow the tool manufacturer's specifications for compression force and die selection.
Is this lug rated for outdoor use?
The tin-plated copper construction provides corrosion resistance. Suitability for specific outdoor or wet location applications depends on the complete installation meeting applicable NEC and local code requirements.
Can this lug be used with aluminum wire?
No. This lug is designed for copper conductors only. For aluminum wire applications, use a bi-metal lug or aluminum-rated compression terminal.
