Split bolts are essential electrical connectors used for securely joining or splicing conductors in power, grounding, and bonding applications. Made from high-strength copper alloy, split bolts provide excellent conductivity and resistance to corrosion, ensuring long-lasting, reliable performance in both indoor and outdoor environments. These connectors are ideal for copper and Copperweld conductors and come in various sizes to accommodate different wire gauges, ranging from 16 AWG to large conductors used in heavy-duty power systems.

Split bolts, such as the Penn Union S series, are versatile and commonly used in above-ground splicing, grounding, and bonding applications. They feature a unique pressure bar design to provide secure connections under high torque, ensuring minimal electrical resistance and maximum durability. The SW series split bolts can also handle aluminum conductors (though not UL-listed for aluminum), making them useful for specific copper-to-aluminum transitions​

Their simple installation process, reusability, and compliance with various industry standards, including UL and CSA certifications, make split bolts a reliable choice for electricians in commercial, residential, and industrial settings.

Key Features:

  • Corrosion-resistant copper alloy construction
  • Suitable for copper and Copperweld wires (some series allow aluminum)
  • Secure connections through high-pressure contact
  • UL and CSA certifications for grounding and bonding applications

These features make split bolts an essential component for ensuring safety and efficiency in electrical systems.
