Burndy KS Series Copper Split-Bolt Connector, Mechanical

Burndy KS Series Copper Split-Bolt Connector, Mechanical

The Burndy KS Series Copper Split-Bolt Connector is a family of solid copper mechanical splicing connectors engineered for reliable run and tap connections between copper conductors. Offered across 16 models — KS15, KS17, KS173, KS20, KS203, KS22, KS223, KS23, KS25, KS26, KS27, KS29, KS31, KS39, KS44, and KS90 — the KS Series spans a wide range of conductor sizes and combinations to cover common stranded and solid copper wire pairings found in panelboards, junction boxes, service equipment, and other tight wiring enclosures. As a mechanical-style connector, every KS Series model uses a bolt-and-nut split-bolt design to create a secure, low-resistance electrical connection without the need for specialized compression tooling or crimping dies, making the series a practical choice for field technicians who need a fast, reusable splicing method. The copper body across the series is matched to copper conductors to help maintain consistent conductivity across the connection point.

Key Features

• Broad Model Range: 16 available models (KS15 through KS90) accommodate a wide span of copper conductor sizes for both run and tap splice configurations.
• Solid Copper Construction: Copper body delivers strong conductivity and long-term durability, helping the connection resist oxidation and maintain performance over time.
• Mechanical Connection Design: Bolt-tightened split-bolt design allows quick, tool-friendly installation with a standard wrench, avoiding the need for compression crimping equipment.
• Compact, Space-Saving Profiles: Each model in the series is sized for easy fit into panelboards, gutters, boxes, and other confined wiring compartments where clearance is limited.
• Run & Tap Versatility: Every connector in the series supports both straight-through run splices and tap-off connections from a single main conductor, reducing the number of connector types needed on a job.
• Copper-to-Copper Compatibility: Designed specifically for copper conductors, pairing connector material with conductor material to support a consistent, galvanically compatible splice.
• Field-Serviceable: The bolted mechanical connection can be re-tightened or removed for reconfiguration, unlike a permanent compression splice.
