Nsi Industries GL414 Compression Cable Lug 4 Awg 1/4 Inch

Product Description

The NSI INDUSTRIES GL414 is a short-barrel compression cable lug designed for terminating 4 AWG copper conductors in electrical systems rated from 600 volts up to 35 KV. Constructed from high-conductivity tin-plated copper tubing, the GL414 provides low contact resistance and solid corrosion resistance at the termination point. The lug measures 1.5 inches in overall length with a 0.71-inch barrel and accepts a 1/4-inch stud through a single-hole pad. A peephole in the barrel allows visual confirmation of full cable insertion before crimping, reducing the chance of an incomplete termination. Licensed electricians and utility contractors install this lug using a compatible compression tool indexed to die set 3/8/346/29.

The GL414 is suited for terminate, splice, and tap applications across residential, commercial, and industrial electrical installations. Its 35 KV rating makes it appropriate for both low-voltage and medium-voltage power distribution work. For any application exceeding 2,000 volts, the lug must be installed per the cable manufacturer's voltage stress relief instructions. The gray color coding and stamped die index simplify field identification and quality control during inspection.

Key Features

• Short-barrel design with 0.71-inch barrel length for compact termination points
• Peephole confirms complete cable insertion before compression is applied
• Tin-plated copper construction reduces corrosion and keeps contact resistance low
• Rated for use from 600 volts up to 35 KV when properly installed
• Die index 3/8/346/29 marked on lug for fast, accurate tool matching
• UL 486A/B and UL 487 listed for both Canada and the United States

Compatibility

Designed as an OEM-style compression lug for 4 AWG copper conductors requiring a 1/4-inch stud termination in systems operating up to 35 KV.

Installation Notes

Installation should be performed by a licensed electrician following applicable NEC requirements. De-energize and lock out the circuit before installing or replacing any compression lug. Use only the compression tool and die set specified by the die index marked on the lug barrel. For medium-voltage applications above 2,000 volts, follow the cable manufacturer's instructions for voltage stress relief before and after the termination.
