Thomas & Betts BLACKBURN 8H Split-Bolt Connector 8-10 AWG

SKU CH-WVB3-RDQR2

Bronze split-bolt connector joins 8-10 AWG copper conductors at 600 V with 65 in-lb torque and hex-head fastening

  • Product typeElectrical Connectors
  • Handles 8-10 AWG copper conductors for versatile splicing
  • Hex head design allows secure tightening with standard tools
  • Bronze body resists corrosion for long-lasting connections
  • Rated for 600 V maximum voltage in electrical applications
  • Compact 0.78 in length fits tight junction spaces

BLACKBURN 8H Split-Bolt Connector

The BLACKBURN 8H Split-Bolt Connector joins copper conductors from 8 AWG stranded down to 10 AWG solid. It is intended for electricians and technicians making permanent tap, run or parallel splices in residential or light-commercial wiring. The bronze body and hex-head design suit field installation with standard hand tools.

Wire-range compatibility 8-10 AWG

This connector accepts a minimum equal wire size of 10 AWG and a maximum equal wire size of 8 AWG. The same range applies to run and tap conductors. Selecting wire outside this 8 to 10 AWG window will prevent a secure mechanical and electrical joint.

Rated 600 V with 65 in-lb torque

The connector carries a maximum voltage rating of 600 V. Proper installation requires tightening the hex nut to 65 in-lb, which ensures low-resistance contact and limits temperature rise under load. The plain bronze finish provides corrosion resistance in typical indoor and covered outdoor environments.

Questions about this item

What does the 600 V rating mean once this connector is installed in a circuit?

The 600 V rating is the maximum voltage the connector is designed to handle safely in service. It must not be used on circuits that exceed this voltage.

How does the hex head and 0.5 in nut size affect the tooling and torque needed for a secure joint?

A 0.5 in hex socket or wrench is required. The manufacturer specifies a torque of 65 in-lb to achieve a reliable connection on 8 to 10 AWG copper conductors.

What clearance is needed to fit the connector given its 0.78 in length and 0.38 in width?

The body measures 0.78 in long by 0.38 in wide, so the enclosure or splice box must provide at least that much space around the joint for the connector and the tightened nut.
