What Are Split Bolt & Grounding Connectors?

Split bolt and grounding connectors are mechanical electrical connectors used to join, bond, splice, and ground conductors. They help create safe, reliable electrical connections in grounding systems, industrial equipment, utility infrastructure, and electrical installations.

Common types include:

• Split Bolt Connectors for splicing and tapping conductors.
• Ground Rod Clamps for connecting wires to ground rods.
• Pipe Ground Clamps for bonding pipes and conduit.
• Service Post Connectors for stud-mounted conductor connections.
• Flat Bar Clamps for grounding bus bars and flat surfaces.
• Bronze Grounding Clamps for corrosion-resistant applications.

Common Applications

Split bolt and grounding connectors are commonly used for:

• Electrical grounding and bonding
• Ground rod and rebar connections
• Industrial equipment and machinery
• Utility and substation grounding

How Do Split Bolt Connectors Work?

Split bolt connectors create a secure electrical and mechanical connection by clamping conductors together with controlled pressure. While installation requirements vary by application and product, the general process includes:

1. Select the correct split bolt for the conductor material, wire size, and number of conductors.
2. Position the conductors inside the split bolt body.
3. Tighten the bolt and nut according to the manufacturer's specifications.
4. Apply the required torque to create a strong, low-resistance electrical connection.
5. Inspect the connection to ensure it meets grounding, bonding, or splicing requirements.

A properly installed split bolt helps provide reliable conductivity, secure conductor retention, and long-term performance in grounding and bonding systems.

Copper vs. Aluminum Split Bolts

Copper split bolts are commonly used for grounding, bonding, splicing, and copper conductor connections.

Aluminum split bolts are designed for aluminum conductors and approved copper-to-aluminum applications when specified by the manufacturer.

How to Choose the Right Grounding Connector

When selecting a grounding connector, consider the following:

• Conductor material: Copper or aluminum
• Wire size: Confirm the supported conductor range
• Connection type: Split bolt, clamp, service post, or other connector
• Installation environment: Indoor, outdoor, underground, or direct burial
• Corrosion resistance: Choose materials suited to the application environment
• Approvals: Verify applicable UL, CSA, or project-specific requirements

Why Proper Grounding Matters

Proper grounding and bonding help maintain electrical continuity, improve electrical system safety, and provide a reliable path for fault current. Selecting the correct grounding connector and installing it according to manufacturer specifications helps support dependable, long-term electrical performance.
