FAQ
What crimp pattern is required for a long barrel lug?
Long barrel lugs accommodate multiple crimps along the barrel length. Use a crimp tool rated for 250 MCM copper conductors with the appropriate die set, following the tool manufacturer's recommended crimp pattern to ensure full barrel compression and proper electrical contact.
Is this lug rated for the conductor size stamped on it?
Yes. The yellow color code and 250 MCM marking indicate this lug is specifically designed and rated for 250 MCM copper conductors. Do not use with aluminum conductors or with copper conductors outside the specified size range.
What does the 35 kV voltage rating indicate?
The 35 kV rating specifies the maximum voltage class for which this lug is designed when properly installed. Verify system voltage requirements and applicable electrical codes for your specific installation.
