Nsi Industries AL1/0-48 Aluminum Compression Lug 1/0 Awg

Product Description

The NSI INDUSTRIES AL1/0-48 is an aluminum compression lug designed for terminating 1/0 AWG aluminum or copper conductors. It accepts a 1/2 inch bolt for secure mechanical connection to busbars, equipment lugs, or other termination points. Rated AL9CU, this lug is listed for use with both aluminum and copper conductors, making it a versatile termination solution. The tan color coding aids in quick identification of conductor size during installation. Electricians and electrical contractors use this lug in panel terminations, service entrance work, and equipment grounding or power connections where aluminum conductors are common.

This compression lug is suited for residential and light commercial electrical installations where 1/0 AWG aluminum conductors require a reliable, code-compliant termination. Typical applications include service entrance panels, meter bases, load centers, and large equipment connections. The AL9CU rating means it is approved for direct contact with both aluminum and copper conductors, reducing the need for anti-oxidant compounds at the termination point, though local code and best practices may still require their use.

Key Features

• AL9CU rating allows use with both aluminum and copper conductors
• Sized for 1/0 AWG conductors
• 1/2 inch bolt hole for secure mechanical attachment
• Tan color coding for fast conductor size identification on the job
• Compression-style termination for a consistent, low-resistance connection

Compatibility

Designed as an OEM-style compression termination lug for 1/0 AWG aluminum or copper conductors requiring a 1/2 inch bolt connection point.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the circuit before installing or removing any compression lug. Use a calibrated compression tool appropriate for aluminum lugs to achieve a proper crimp — under-crimping can result in a high-resistance joint. Inspect the conductor end for oxidation and apply anti-oxidant compound as required by local code or the authority having jurisdiction.
