Mechanical lug · 300-800 kcmil AL-CU · 1 conductor 1-hole 5/8 in stud · Ilsco T· 800

What this product is for

The Ilsco TA-800 is a one-conductor, one-hole mechanical terminal lug for terminating large aluminium or copper conductors in power distribution equipment. It is used where a bolted mechanical connection is preferred for service, feeder, grounding, or equipment terminations.

Use for

Use for 300 to 800 kcmil conductors, panelboards, switchgear, transformers, wireways, and other equipment with a 5/8 in stud connection. This lug is dual-rated for aluminium and copper conductors and is commonly selected for field-installed power terminations.

Avoid for

Avoid using where a two-hole lug is specified for added pad stability, where the conductor size falls outside the listed range, or where the equipment manufacturer requires a different lug pattern or torque value. Do not substitute based on appearance alone.

Best for

Best for electricians and contractors needing a one-hole mechanical lug for large conductors in commercial and industrial distribution work. It suits applications where serviceability, conductor range, and AL-CU compatibility matter more than a compression connection.

Installed in

Typically installed in electrical rooms, service equipment, distribution sections, MCCs, switchboards, and industrial control or power assemblies. Verify fit, stud size, conductor class, and required clearances before ordering.

Why this product exists

This lug provides a field-installable bolted termination for large conductors without requiring a compression die system. The wide conductor range can help reduce SKU count on service trucks and in stock rooms.

Compared with similar products

Compared with compression lugs, a mechanical lug installs with standard tools and can simplify maintenance or replacement. Compared with two-hole lugs, this one-hole design takes less mounting space but may offer less resistance to rotation, so equipment requirements should guide selection.
