Split bolt connectors join conductors without soldering, providing secure electrical connections for splicing, tapping, and grounding applications. They excel in low-voltage environments such as tracer splices and cathodic protection systems up to 50V, though some variants support voltages up to 2000V. The split design enables quick wire insertion and installation while maintaining low-resistance connections that minimize voltage drop.
Construction typically uses high-conductivity metals including copper, aluminum, or bronze alloys to ensure optimal electrical flow and corrosion resistance. Some variants come prefilled with silicone for corrosion prevention, while others feature high-strength bronze or copper alloys for enhanced mechanical properties. Plating options such as copper coating or electro tin improve durability across diverse environmental conditions.
The split bolt configuration accommodates wire insertion through a gap that closes when the hex nut tightens, forming secure contact between conductors. Models feature different thread forms including ISO metric or American Unified threads, with bolt dimensions like 19/32 x 1-1/4 inches engineered to provide consistent contact pressure. Pressure bars maintain stability across the connection point.
These connectors handle conductor sizes from #16 to #4/0 American Wire Gauge (AWG) for solid or stranded wires, supporting copper-to-copper or copper-to-aluminum connections. Applications span power distribution, industrial installations, electric fence systems, and direct burial in earth or concrete. Underwriters Laboratories (UL) listing on many models ensures compliance with safety standards.

Frequently Asked Questions (FAQS)
What are the common applications for split bolt connectors?
Split bolt connectors are used for splicing, tapping, and terminating conductors in grounding applications, low voltage tracer splices up to 50V, cathodic applications, and electric fence installations, providing secure and reliable connections.
What materials and wire sizes are split bolt connectors available in?
Split bolt connectors are made from high-quality materials such as copper, aluminum, bronze alloy, steel, or brass, ensuring superior conductivity, durability, and corrosion resistance. They accommodate a range of AWG sizes, including #8 to #10, #6 to #2, and up to 4/0 AWG, for both solid and stranded copper conductors.
How easy is it to install a split bolt connector?
The unique split design allows for easy wire insertion and quick, secure connections, making installation straightforward and time-efficient without specialized tools.
Are split bolt connectors suitable for harsh environments and direct burial?
Yes, many split bolt connectors are designed with corrosion-resistant features, such as being prefilled with silicone or SmartGel, and made from materials like bronze alloy or copper-plated aluminum. Certain models are suitable for direct burial in earth and concrete, as they are built to withstand harsh conditions and maintain integrity underground.
How do I determine how many split bolt connectors I need for a project?
For applications like electric fences, calculate by multiplying the number of end posts by the strands, adding for fence lines over 1,000 feet, and including additional connectors for extra connections. RaxPower offers reliable connectors to meet your project needs.
