Split-Bolt Connector 1/0 to 4 AWG

The Thomas & Betts Blackburn 10H split-bolt connector joins copper conductors ranging from 4 AWG up to 1/0 AWG. It provides a secure mechanical connection for run and tap wires in electrical installations. The bronze body with plain finish suits standard copper wiring applications. A hex head design allows tightening with common tools.

For copper conductor splicing up to 600 volts

This connector suits electricians and installers joining equal or unequal copper wires within the 4 AWG to 1/0 AWG range at voltages up to 600 V. It is not for aluminium or other non-copper conductors. Buyers needing insulated bodies, smaller wire gauges, or higher voltage ratings should look at alternative connector types.

Handles 4 AWG to 1/0 AWG copper at 600 V

The connector comfortably accommodates run and tap wires from 4 AWG through 1/0 AWG with a torque rating of 65 in-lb. It runs out beyond 1/0 AWG maximum wire size or above the 600 V limit. Overall length is 1.59 in and head width is 0.75 in for space planning in enclosures.

Questions about this item

What minimum copper wire gauge must I already have to use this 1/0-to-4 AWG split-bolt connector?

The connector accepts copper conductors from 4 AWG up to 1/0 AWG for run and tap, so you need at least a 4 AWG copper wire.

Can I reuse my existing 6 AWG copper conductors with this connector rated for 4 AWG minimum?

No, the minimum equal, run and tap wire size is 4 AWG; 6 AWG is too small for a secure connection.

How can I verify the connection is properly torqued after installing the hex-head split-bolt?

Tighten the hex nut to 65 in-lb using a torque wrench on the 0.938 in hex; the joint should show no movement at 600 V rating.
