Square D LK100AN QO Load Centre Neutral Lug, 100 A Rated Current, 40 lb.in Tightening Torque

Description

Features

• This field-installable Square D load center lug kit is engineered for seamless physical integration into both premium QO and standard Homeline load centers. It acts as a direct factory-spec upgrade, allowing residential and commercial electricians to securely mount the accessory directly onto the existing neutral bar or grounding assembly without compromising the panel's interior structural layout.
• Featuring a robust continuous current rating of 100 A, this auxiliary neutral lug is designed to handle high-amperage return currents without overheating. It provides electrical contractors with a code-compliant solution for terminating larger main neutral or grounding conductors inside sub-panels and service entrance enclosures, ensuring system-wide electrical stability.
• Built for high field adaptability, the heavy-duty mechanical barrel accepts a wide range of wire sizes from AWG 6 up to 2/0 AWG. The dual-rated internal clamp geometry is fully certified for use with both copper and aluminum building wire, allowing installers to terminate thick feeder lines easily while maintaining optimal high-pressure physical retention.
• Designed as a rugged bolt-on component, this single-barrel lug securely mounts to the panel's internal distribution bar by spanning and occupying multiple screw positions. This wide physical footprint distributes the mechanical tightening torque evenly, delivering a rock-solid, vibration-resistant electrical bond that prevents localized contact impedance and long-term hot-spot generation.
• To eliminate guesswork during rough-in inspections, the mechanical screw clamp is factory-rated for a specific tightening torque of 40 lb-in across the entire AWG 6 to 2/0 conductor range. This high-torque threshold prevents connection loosening caused by thermal expansion and cyclic cooling, ensuring a gas-tight, low-resistance termination over decades of panel service.
• This authentic Schneider Electric component is fully UL Listed and CSA certified for use in factory-warranted Square D enclosures. Using this verified OEM part ensures your modified panel assemblies pass field inspections cleanly, keeping the underlying infrastructure compliant with strict provincial electrical safety regulations and corporate insurance requirements.
