The Conversions Tech 2-hole copper compression lug terminates 300 MCM conductors in medium-voltage industrial and commercial electrical systems. This short-barrel lug features a 1/2-inch bolt size, tin-plated seamless copper construction, and a sight window for visual inspection of conductor insertion depth. The red color code identifies the conductor size at a glance, while the chamfered barrel entry eases installation. Rated for 35 kV and 90°C continuous operation, it suits switchgear, transformers, motor connections, and power distribution equipment where reliable high-current termination is required.

FAQ
What crimping tool and die are required for this lug?
Use a standard 12-ton or larger hydraulic crimper with die index I-66. The chamfered barrel entry accepts the conductor smoothly; crimp through the sight window area to verify full insertion before final compression.
Is this lug suitable for 600V applications as well as medium voltage?
Yes. The 35 kV rating exceeds 600V requirements, making it suitable for both low-voltage and medium-voltage installations. The 90°C temperature rating aligns with standard copper conductor ampacities per NEC.
Why does a 300 MCM lug use a 1/2-inch bolt instead of 3/8-inch?
The 1/2-inch stud size provides higher mechanical strength and clamping force for high-current terminations. Verify your equipment bus bar or terminal block accepts 1/2-inch hardware before ordering.
