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.

Burndy ASA800U – Frequently Asked Questions

1) What does the Burndy ASA800U stacking adapter actually do on a connection point?
The ASA800U is a Hystack mechanical stacking adapter that lets you land two or four hole copper or aluminum terminals on one connection point instead of running separate landing hardware. Its 2-slot body accepts two terminal connections, so you can build up a multi-terminal assembly on a single stud or pad in switchgear, panelboards, and utility distribution gear.
2) Can I use the ASA800U with aluminum conductors, or is it copper only?
Both. The ASA800U is dual rated Al/Cu, so copper and aluminum terminals can be landed on it, including mixed conductor types on the same connection point. The body is aluminum with a tin plated finish, which is what makes the dual rating and the aluminum contact possible.
3) What is the largest conductor the ASA800U will handle?
Up to 800 kcmil. That is the conductor rating on the Burndy ASA800U, and it also allows 1.37 inch insulation outside diameter, so heavy insulated feeder cable clears the adapter without the jacket fouling the landing. If your feeders are larger than 800 kcmil, you need a different size in the Hystack line.
4) Does the ASA800U work with 2-hole and 4-hole lug patterns?
Yes, the adapter accepts 2-hole or 4-hole copper or aluminum terminals, so you are not locked into one NEMA hole pattern when you stack. Confirm your lug pad hole spacing matches what you are stacking, but both patterns are supported on the ASA800U.
5) Will 1.37 inch insulation OD clear my cable jacket?
The ASA800U is dimensioned for 1.37 inch insulation outside diameter. Measure over the jacket of your 800 kcmil cable, not the conductor, since oversized or double jacketed cable can exceed that and interfere at the adapter. Anything at or under 1.37 inches seats without interference.
6) Is the Burndy ASA800U a compression fitting or mechanical?
Mechanical. The ASA800U is a mechanical stacking adapter, so it assembles and comes apart with hardware in the field. No die set or crimp tool is involved, which matters if you expect to reconfigure or add a terminal to the stack later.
7) How many terminals can I stack on one ASA800U?
Two. The 2-slot configuration takes two terminal connections. If you need to land more than two terminals at one point, you will need additional slots, not additional torque on this one; the slot count is fixed on the ASA800U.
8) Is the tin plating on the ASA800U necessary for aluminum terminations?
Tin plating is what keeps the ASA800U from setting up galvanic and oxidation problems at the interface. On an aluminum body it gives a corrosion resistant, stable low resistance contact surface, which is why the adapter can carry both copper and aluminum terminals. For outdoor or industrial environments that is the finish you want on a stacked connection.
9) What part number do I order for the 800 kcmil Hystack stacking adapter?
Order Burndy ASA800U. That is the manufacturer part number for the 800 kcmil, 2-slot, tin plated Al/Cu Hystack stacking adapter, and it is a single configuration with no finish or size options to specify.
