8H

Overview

The Blackburn 8H is a Type H high strength split bolt connector designed for solid or stranded copper conductors ranging from 10 to 8 AWG. Constructed from bronze alloy, it features a hex head split bolt and nut with a 3/8-inch thread size. The unit provides a 0.146-inch split width and measures 1/2 inch in length by 25/32 inch in height. Rated for 600V applications, it supports splicing, tapping, and terminating connections in power and grounding systems.

Feature Summary

• High strength construction utilizing corrosion-resistant bronze alloy for the bolt, nut, and pressure bar
• Designed specifically for secure copper-to-copper electrical connections
• Hex head installation mechanism allows for standard tool engagement

Applications

• Splicing solid or stranded copper conductors
• Tapping into existing copper wiring circuits
• Terminating conductors in power distribution systems
• Grounding electrical connection installations

Procurement Notes

Verify that the required conductor size falls within the 10 to 8 AWG range for both solid and stranded copper wires. Confirm the application voltage does not exceed 600V. Ensure the installation environment is compatible with bronze alloy materials. Check for specific UL listing requirements such as E9809 if mandated by local codes. Match the hex nut size to available tools.

Selection Notes

Select this component when joining copper conductors between 10 and 8 AWG in power or grounding circuits. It is suitable for environments requiring high mechanical strength and corrosion resistance. Consider the bronze alloy material for durability. Ensure the installation method accommodates the hex head split bolt design. Verify compatibility with solid and stranded wire types before procurement.

Part Context

This part belongs to the Blackburn series of split bolt connectors, now under the ABB T&B brand portfolio. The Type H designation indicates a high-strength variant optimized for copper conductors. These connectors are standard components in electrical infrastructure for reliable mechanical and electrical joints without soldering.

Replacement Considerations

Compatible manufacturer model number is 8H. ABB offers equivalent high strength split-bolt connectors for copper to copper connections. Verify dimensional compatibility and material specifications when substituting.
