Aluminium Mechanical Lug · 1-Conductor, 1-Hole · #4 AWG to 500 kcmil Cu/Al Range · Techspan LA500
SKU: LA500
Single-conductor aluminium mechanical lug for terminating #4 AWG to 500 kcmil copper or aluminium conductors on a one-hole pad connection. Commonly used in panels, switchgear and equipment terminations where a mechanical set-screw lug with a wide wire range is required.
What this product is for
This aluminium mechanical lug is used to terminate one conductor onto equipment or bus connections with a single mounting hole. It fits a broad conductor range from #4 AWG to 500 kcmil, making it suitable for service, distribution and equipment termination work.
Use for
Use for copper or aluminium conductors where a one-conductor, one-hole mechanical termination is specified. Common applications include panelboards, switchboards, disconnects, transformers and other power distribution equipment.
Avoid for
Avoid using this lug where a two-hole lug is specified for added pad stability, where the conductor size falls outside the listed range, or where the equipment termination requires a different stud size, tongue pattern or connector material.
Best for
Best for electricians and contractors needing a field-installable mechanical lug for larger feeders and distribution conductors without using a compression connector. A mechanical lug is commonly chosen when serviceability and broad conductor range matter.
Installed in
Typically installed in electrical rooms, service equipment, distribution sections, control enclosures and OEM assemblies. Typical mounting uses a single-hole pad connection; always confirm the required stud size and torque from the equipment and connector documentation before installation.
Why this product exists
This type of lug provides a practical way to terminate larger copper or aluminium conductors using a mechanical set-screw connection instead of a crimped compression lug. That can simplify installation, replacement and maintenance in the field.
Compared with similar products
Compared with compression lugs, a mechanical lug is typically faster to install and easier to service in the field. Compared with two-hole lugs, a one-hole lug takes less pad space but may offer less resistance to rotation, so equipment specifications should guide the choice.
Specifications
- Product type: Mechanical lug
- Material: Aluminium, typically tin-plated on comparable LA-500 style lugs
- Conductor capacity: 1 conductor
- Mounting: 1-hole
- Wire range: #4 AWG to 500 kcmil
- Conductor compatibility: Copper or aluminium on comparable dual-rated LA-500 style listings
- Typical stud size on comparable listings: 3/8 in (9.5 mm) — verify before ordering
- Typical application voltage on comparable listings: up to 600 V — verify against project requirements
- Installation note: Follow manufacturer torque values and approved conductor preparation methods.
Typical buying guidance: one-hole mechanical lugs are commonly used where pad space is limited, while two-hole lugs are often preferred where vibration resistance or anti-rotation is important. Actual suitability depends on equipment design, conductor type, installation conditions and local electrical code.
