Copper Cable Lug Types

Different copper cable lug designs are available to match conductor sizing systems, equipment interfaces and installation requirements.

Standard Copper Compression Lugs

Standard compression lugs are used for common copper cable termination requirements. Select the model according to conductor size, stud hole and lug dimensions.

WISETREE offers multiple copper lug series, including SC and other tubular compression designs for different cable and equipment requirements.

DIN Copper Cable Lugs

DIN-designated copper cable lugs are available for projects where a defined dimensional series is specified.

When selecting a DIN product, confirm:

• Cable cross-section

• Conductor construction

• Stud hole

• Required DIN series

• Product dimensions

Refer to the specific DIN product page for detailed size information.

AWG Copper Cable Lugs

For projects using AWG cable sizing, select a copper lug designed around the corresponding AWG conductor range.

Confirm both the AWG size and equipment-side mounting dimensions before ordering.

Long Barrel Copper Lugs

Long-barrel lugs provide a longer conductor insertion and compression section than standard barrel designs.

Where a long-barrel configuration is specified, confirm the required barrel length, conductor size and overall lug dimensions against the product specification.

2-Hole and Multi-Hole Copper Lugs

Some equipment interfaces require more than one mounting point.

For 2-hole or multi-hole lugs, confirm:

• Stud diameter

• Number of holes

• Hole spacing

• Palm width

• Palm thickness

• Equipment mounting pattern

Angled Copper Cable Lugs

Straight lugs are not suitable for every installation.

Where cabinet space, cable routing or terminal orientation is restricted, angled cable lugs such as 45° or 90° configurations may provide a more suitable termination layout.

Confirm the lug angle and equipment connection direction before ordering.

Copper Cable Lug Selection Guide

Use this table for initial product selection. Confirm the final model against the dimensions and specifications of the individual product.

Key Specifications for Copper Cable Lug Selection

Use the following parameters when comparing models or preparing a quotation request.

If your project includes multiple conductor sizes, send the complete cable schedule so the required models can be reviewed together.

Copper Material and Surface Options

Material and surface condition affect electrical contact, corrosion resistance and long-term installation performance.

Different WISETREE copper cable lug series may use different copper specifications or surface treatments according to their design.

Available product options may include:

• Bare copper

• Tin-plated copper

• Model-specific copper grades

• Project-specified surface requirements

Do not assume that the same copper grade or plating specification applies to every product series.

If your project specifies copper purity, material grade, plating or coating requirements, include those details when requesting a quotation so the appropriate product can be confirmed.

DIN and AWG Copper Cable Lug Options

Copper cable lug dimensions can vary according to the cable sizing system and product series.

WISETREE's current range includes both DIN-designated and AWG-related copper lug products.

For DIN Requirements

Provide:

• Cable cross-section

• Conductor type

• Required DIN series

• Stud hole

• Quantity

For AWG Requirements

Provide:

• AWG conductor size

• Stud hole

• Hole configuration

• Required dimensions

• Quantity

Always confirm dimensional compatibility against the individual product specification rather than selecting only by the DIN or AWG designation.

Straight, 2-Hole and Angled Lug Configurations

The equipment-side connection is as important as the conductor-side barrel.

Single-Hole Copper Lugs

Suitable where the equipment uses a standard single-stud connection.

Confirm the stud hole and palm dimensions.

2-Hole Copper Lugs

Use a 2-hole design where the equipment requires two mounting points.

Confirm:

• Stud diameter

• Hole spacing

• Palm width

Angled Copper Lugs

Use an angled lug when a straight connection would create cable routing or installation-space problems.

For 45° or 90° designs, verify the required orientation against the actual equipment layout before ordering.

Custom Copper Cable Lugs

Standard catalogue dimensions do not fit every switchgear, transformer, busbar or equipment interface.

WISETREE can review project-specific copper cable lug requirements according to manufacturing feasibility.

Custom requirements may include:

• Conductor size

• Barrel inner and outer dimensions

• Barrel length

• Palm width

• Palm thickness

• Stud hole diameter

• Hole quantity

• Hole spacing

• Straight or angled configuration

• Overall dimensions

• Surface treatment

• Product marking

• Packaging

For custom copper cable lugs, send a drawing or sample together with the conductor specification, equipment interface and estimated order quantity.

If no formal drawing is available, clear dimensional information can be used for an initial review.

Frequently Asked Questions

How do I choose the correct copper cable lug size?

Start with the copper conductor cross-section, then confirm the conductor construction, barrel dimensions, stud hole and equipment mounting interface. Do not select the lug only by nominal cable size.

What is the difference between DIN and standard copper cable lugs?

DIN-designated cable lugs follow a defined dimensional series, while other copper lug series may use different dimensional systems or manufacturer-specific designs. If your project specifies a DIN requirement, include the exact specification in your RFQ.

How do I select the correct stud hole size?

Match the lug hole to the equipment stud or bolt. When replacing an existing lug, measure or confirm the terminal stud before selecting the new product.

When should I use a 2-hole copper cable lug?

Use a 2-hole lug when the equipment connection requires two mounting points. Confirm both the stud diameter and hole spacing before ordering.

What is the difference between standard and long-barrel copper lugs?

A long-barrel lug has a longer conductor insertion and compression section. Select it only where the project or installation method requires that barrel configuration.

Can the same copper lug be used for stranded and flexible conductors?

Not necessarily. Conductor construction can affect compatibility with the lug barrel and crimping system. Provide the conductor type when requesting product matching.

Do you supply AWG copper cable lugs?

Yes. WISETREE's current range includes AWG-related copper cable lug products. Provide the AWG conductor size, stud hole and required mounting configuration for model selection.

Can copper cable lugs be customized to my drawing?

Project-specific dimensions and configurations can be reviewed according to manufacturing feasibility. Send the drawing, conductor specification, required dimensions and estimated quantity for evaluation.
