Product Description

The ABB L1252 is a Type L copper terminal lug designed for single-conductor terminations in electrical distribution and wiring applications. It features a two-hole mounting configuration and a socket-style barrel, accepting conductor sizes from 4 STR through 1/0 STR. The lug measures 2.8125 inches in length, 0.78125 inches in width, and 0.8125 inches in height. Licensed electricians and panel technicians use this style of lug for secure, code-compliant terminations at bus bars, disconnect switches, and similar equipment. The all-copper construction ensures low-resistance connections in both residential and light commercial panels.

The L1252 lug is suited for use in load centers, switchboards, disconnects, and similar electrical enclosures where a bolted, two-hole lug termination is required. Its conductor range covers 4 STR through 1/0 STR, making it appropriate for branch circuit and feeder terminations at typical residential and commercial service ampacities. Installation is performed by licensed electricians following NEC guidelines for conductor terminations and torque requirements.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC Article 110 torque and termination requirements. De-energize and lock out the circuit before installing or removing any terminal lug. Use a calibrated torque wrench or screwdriver to achieve the equipment manufacturer's specified bolt torque for the two-hole mount fasteners. Inspect the conductor end for nicks or damage before seating it fully into the socket barrel.
