The Conversions Tech short barrel one-hole compression lug is engineered for high-current electrical terminations in commercial, industrial, and utility applications. This copper compression lug accommodates 300 MCM conductor with a 5/16-inch bolt size for secure attachment to busbars, switchgear, and equipment terminals. The standard straight barrel design with chamfered cable entry facilitates installation, while the integrated sight window provides visual confirmation of proper conductor insertion prior to crimping.

FAQ
What crimping tool and die are required for this lug?
This lug requires an I-66 die index for proper compression. Use a manufacturer-calibrated hydraulic or battery-powered crimping tool rated for 300 MCM copper compression lugs. Verify die compatibility before installation.
Is this lug rated for outdoor or wet location use?
The electro-tin plated copper construction provides corrosion resistance. For outdoor or wet location applications, additional environmental protection such as tape or heat-shrink insulation may be required per NEC and local code. The 90°C temperature rating and 35kV rating apply to the lug itself.
Can this lug be used with aluminum conductor?
No. This lug is specified for copper conductor only (300 MCM copper). Using with aluminum conductor requires a different product series with appropriate material compatibility and oxide-inhibiting compounds.
