Burndy ASA800U Hystack 2-Slot Terminal Stacking Adapter, Al/Cu, 800 kcmil

Burndy ASA800U Hystack 2-Slot Terminal Stacking Adapter, Al/Cu, 800 kcmil

The Burndy ASA800U is a Hystack series terminal stacking adapter engineered for dual-rated aluminum and copper (Al/Cu) applications, allowing installers to stack 2- or 4-hole copper or aluminum terminals on a single connection point. Rated for conductors up to 800 kcmil with a 1.37" insulation outside diameter, this tin-plated mechanical adapter delivers a secure, corrosion-resistant termination for demanding power connector assemblies used in utility and industrial power distribution. Its 2-slot configuration simplifies multi-terminal stacking without sacrificing connection integrity, and its dual Al/Cu rating gives electricians flexibility when terminating mixed conductor types on the same connection point.

Key Features

• Max Conductor Size: Rated for conductors up to 800 kcmil, supporting heavy-gauge power connections.
• Dual Al/Cu Rating: Compatible with both copper and aluminum 2- or 4-hole terminals for flexible application across conductor types.
• 2-Slot Configuration: Stacking adapter design accepts two terminal connections in a compact footprint, reducing the need for separate hardware.
• Tin-Plated Finish: Tin plating resists corrosion and helps maintain a stable, low-resistance conductive connection over time.
• Insulation Clearance: 1.37" insulation outside diameter accommodates common insulated conductor sizes without interference.
• Hystack Series Design: Part of Burndy's Hystack line of mechanical stacking connectors built for reliable, repeatable terminal assemblies.
• Mechanical Connector Type: Mechanical stacking adapter construction simplifies field assembly and terminal reconfiguration.
