Mechanical Lug · 4 AWG to 3/0 AWG Copper · 1-Hole Offset Tongue · Techspan SLU175
What this product is for
This copper mechanical lug is used to terminate one stranded copper conductor in the 4 AWG to 3/0 AWG range to equipment pads, bars or terminals using a single mounting hole. The offset tongue helps when aligning larger conductors to a flat connection point.
Use for
Use for panelboards, switchgear, distribution equipment, grounding and bonding assemblies, and other power connections where a mechanical set-screw lug is specified. Suitable where a 3/8 in stud connection and a compact one-conductor lug are needed.
Avoid for
Avoid using this lug with conductor sizes outside the listed range, with incompatible conductor material, or where a compression lug is specifically required by the equipment manufacturer or project specification. Do not assume suitability for fine-stranded or flexible cable unless the installation requirements confirm compatibility.
Best for
Best for electricians and contractors needing a field-installable copper lug for service, distribution or equipment terminations using stranded copper conductors from 4 AWG to 3/0 AWG.
Installed in
Typically installed in electrical rooms, control panels, switchboards, meter bases, disconnects and other indoor or protected electrical enclosures. Actual application depends on enclosure rating, conductor type and local electrical code.
Why this product exists
This style of mechanical lug provides a practical alternative where a bolted, set-screw termination is preferred for serviceability and field installation. The offset tongue and single-collar body are designed to secure the conductor while landing on a single-hole pad.
Compared with similar products
Compared with compression lugs, a mechanical lug installs without a crimp tool and is commonly chosen for maintenance, retrofit and equipment terminations. Compared with two-hole lugs, this 1-hole version is better where space is limited or the equipment pad is drilled for a single stud, though anti-rotation performance depends on the equipment connection design.
