The Conversions Tech Copper Short Barrel One Hole Compression Lug is engineered for terminating 250 MCM copper conductors in industrial and commercial electrical systems. The short barrel profile reduces overall footprint for crowded termination cabinets, switchgear, and control enclosures where space is constrained. Electro-tin plating provides oxidation resistance for long-term reliability in standard indoor and outdoor electrical installations.

FAQ
What crimping tool die should I use with this lug?
Use die index I-62 with compatible compression tools. Verify proper die alignment and full compression cycle per tool manufacturer instructions.
Is this lug rated for 90°C conductor ampacity?
Yes, the 90°C temperature rating supports full ampacity of 250 MCM copper conductors per NEC ampacity tables when installed in properly rated enclosures and conditions.
Can this lug be used in wet locations?
The electro-tin plating provides corrosion resistance; however, suitability for wet locations depends on overall enclosure rating and installation method. Verify compliance with NEC Article 312 and specific job specifications.
