Split Bolt Connector · 2 to 3/0 AWG copper conductors · dual conductor copper alloy · Techspan S3/0

What this product is for

The Techspan S3/0 is a copper alloy split bolt connector used to join or tap two copper conductors. It is suited to electrical maintenance, grounding, bonding, and power distribution work where a field-installed mechanical connector is required.

Use for

Use for copper-to-copper conductor splicing or tapping within the listed conductor range of 2 to 3/0 AWG, solid or stranded where specified by the manufacturer listing. This style is commonly selected when electricians need a compact bolted connector that can be installed and reworked on site.

Avoid for

Avoid using this connector outside its listed conductor range, on incompatible conductor materials unless specifically rated, or in applications that require an insulated or compression-style connector. Follow local electrical code and the manufacturer installation requirements.

Best for

Best for service and grounding connections, equipment bonding, and general copper conductor taps where mechanical tightening and future access are important. It can also be a practical choice for repair work where crimp tooling is not preferred.

Installed in

Typically installed in electrical rooms, service equipment, junction boxes, grounding systems, and other dry or protected locations, depending on enclosure and code requirements. For exposed or corrosive locations, use only where the overall connection method is suitable for the environment.

Why this product exists

Split bolt connectors provide a straightforward mechanical method to join conductors without compression tools. For many contractors, they remain a common choice for accessible copper splices and taps because installation is simple and conductor contact is direct.

Compared with similar products

Compared with compression connectors, a split bolt can be easier to install and service in the field but depends on correct tightening and proper taping or insulating where required. Compared with insulated mechanical connectors, it is more compact and often more economical, but it is not an insulated finished connection by itself.

Typical trade guidance: split bolt connectors are often chosen where future access or re-entry may be needed. Actual suitability depends on conductor type, enclosure, insulation method, and local electrical code.
