Nsi Industries L2038 Copper Compression Long Lug 2/0 Awg

Product Description

The NSI INDUSTRIES L2038 is a tin-plated copper compression long lug designed to terminate 2/0 AWG conductors in medium- and heavy-duty electrical installations. The closed barrel construction provides a sealed, moisture-resistant crimp connection that resists vibration and contamination once compressed. A chamfered barrel port guides conductor insertion, and the single mounting hole accepts a 3/8-inch bolt. Black color-coding and a legible die index stamp allow quick identification during installation. Electricians and electrical contractors install this lug using a standard compression crimp tool — no solder required.

This lug is suited for secondary power distribution in residential, commercial, and industrial settings. Typical applications include service entrance terminations, power plant distribution panels, switchgear connections, and terminations on heavy electrical equipment. The long-barrel design provides additional conductor engagement length compared to a standard lug, making it a preferred choice where pull-out resistance and connection integrity are critical in high-demand circuits.

Key Features

• Tin-plated copper construction for improved conductivity and corrosion resistance
• Closed barrel design seals against moisture and contamination
• Chamfered entry port guides 2/0 AWG conductor insertion
• Single mounting hole sized for 3/8-inch hardware
• Black color-coding with legible die index for fast field identification
• Compression crimp installation creates a vibration-resistant, homogenous bond

Compatibility

Designed as an OEM-style compression termination lug for 2/0 AWG copper conductors in single-hole mounting applications across secondary power distribution systems.

Installation Notes

Installation must be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize and lockout/tagout the circuit before terminating any conductors. Use a calibrated compression crimp tool with the die size specified by the manufacturer for 2/0 AWG lugs to ensure a proper crimp. Inspect the barrel after crimping to confirm full conductor seating and no cracking of the plating.
