About BLACKBURN

Blackburn is a brand historically associated with electrical connectors and grounding components for utility, industrial, and commercial power systems. The product line includes mechanical lugs, split bolts, and multitap connectors, with a focus on reliable wire termination and splicing. Blackburn products are commonly specified in distribution panels, switchgear, and grounding networks where durable, reusable connections are required. The brand's catalog covers a range of conductor sizes and stud dimensions to accommodate various installation needs.

3G Electric supplies Blackburn connectors and lugs as part of its industrial equipment portfolio. The available products include straight mechanical lugs with unplated copper bodies, designed for terminating or splicing stranded copper wire. These lugs accept wire sizes from 14 AWG to 500 kcmil and feature stud sizes from 13/64 inch to 13/32 inch. The unplated copper construction provides conductivity and is suitable for applications where a bare copper contact is acceptable. The mechanical design allows for field installation without the need for specialized tooling, although proper torque values should be observed to ensure a secure connection.

Blackburn mechanical lugs are used in electrical panels, switchgear, power distribution blocks, and grounding systems. The range includes models such as the STC0414, STC3104, L125BB, STC0614, STC1102, STC5011, L70, and STC0208, each targeting specific wire size ranges and stud sizes. For example, the STC5011 accommodates 1/0 AWG to 500 kcmil wire with a 13/32 inch stud, while the L70 handles 14 AWG to 4 AWG with a 9/32 inch stud. These lugs are typically made from copper for conductivity and may be used with copper conductors only, as indicated by the product specifications.

3G Electric supports the Blackburn line by maintaining inventory of these connectors and providing logistics support for global delivery. The company serves plant engineers, maintenance managers, and procurement specialists who require specific part numbers and technical specifications. 3G Electric's catalog includes detailed product data, such as stud size, wire range, and material, to facilitate correct selection. For applications requiring multitap connectors or split bolts, 3G Electric can source additional Blackburn products beyond the mechanical lugs listed. The focus is on supplying the correct component for the electrical connection task, with attention to compatibility and installation requirements.

Frequently asked questions

Common questions about BLACKBURN from 3G Electric.

What wire sizes does the Blackburn STC5011 mechanical lug accept?

The Blackburn STC5011 straight mechanical lug accepts stranded copper wire sizes from 1/0 AWG to 500 kcmil. It features an unplated copper body and a 13/32 inch stud size. This lug is designed for terminating copper conductors in applications such as power distribution panels and switchgear. The slotted head allows for tightening with a standard screwdriver or wrench. Proper installation requires stripping the wire to the correct length and torquing the connection to the manufacturer's specification to ensure a low-resistance joint.

Are Blackburn mechanical lugs suitable for aluminum wire?

The Blackburn mechanical lugs listed in 3G Electric's catalog are specified for copper wire only. The product data indicates 'For Wire Material: Copper' and the body material is unplated copper. Using these lugs with aluminum conductors is not recommended unless explicitly stated by the manufacturer, as dissimilar metals can cause galvanic corrosion and connection failure. For aluminum wire applications, alternative connectors rated for aluminum-copper transitions should be used. Always verify the compatibility of the connector with the conductor material before installation.

What is the stud size for the Blackburn L125BB mechanical lug?

The Blackburn L125BB straight mechanical lug has a stud size of 21/64 inch. It accommodates stranded copper wire sizes from 8 AWG to 1/0 AWG. The lug body is made of unplated copper. This model is commonly used in power distribution panels and electrical enclosures where a 21/64 inch stud is provided. The mechanical design allows for easy installation and reusability. Ensure the stud is clean and the lug is properly aligned before tightening to avoid damage to the threads.

Can Blackburn mechanical lugs be used for grounding applications?

Blackburn mechanical lugs are often used in grounding and bonding applications where a reliable connection to a ground bus or electrode is required. The unplated copper body provides good conductivity. However, for direct burial or high-corrosion environments, additional protection may be necessary. The lugs are suitable for connecting grounding conductors to steel structures, ground rods, or grounding bars, provided the wire size and stud size match the application. Always follow local electrical codes and grounding system design requirements when selecting connectors.

What is the difference between Blackburn STC and L series mechanical lugs?

The Blackburn STC and L series are both straight mechanical lugs with unplated copper bodies for copper wire. The primary difference lies in the specific wire ranges and stud sizes. For example, the STC series includes models like STC0414 (14-4 AWG, 17/64 inch stud) and STC5011 (1/0 AWG-500 kcmil, 13/32 inch stud), while the L series includes L125BB (8 AWG-1/0 AWG, 21/64 inch stud) and L70 (14-4 AWG, 9/32 inch stud). The series designation may also reflect different mechanical designs or head styles, such as slotted head versus hex head. Selection should be based on the specific wire size and stud size required for the application.
