Copper / Aluminum HYSTACK™ Terminal Stacking Adapters

TYPE CUSA HYSTACK™ Terminal Stacking Adapter

The HYSTACK™ adapter is specially designed to get terminals to the back end of a bus bar or other areas that require terminals to be elevated off the mounting surface. These HYSTACK™ adapters are made from high conductivity copper and tin-plated to provide optimum corrosion resistance. It will accommodate #10 AWG through 750 kcmil HYLUG™ terminals. Features & Benefits • For use on terminals made from copper • Designed specifically for stacking standard terminals; uses include: • Place the stacking adapter on the mounting plate and a terminal on top of the stacking adapter and bolt down • Placing a stacking adapter on a terminal pad that will be mounted to a bus bar or mounting plate and a terminal on top of the stacking adapter, and bolt down • May be used with standard NEMA two and four hole terminals; to stack four hole NEMA terminations use two stacking adapters assembled side-by-side • Stacking adapters are clearly marked

TYPE ASA-U HYSTACK™ Terminal Stacking Adapter UL Listed 90° C, Up to 35 kV 

The HYSTACK™ adapter is specially designed to allow standard terminals to be stacked on two or four hole NEMA transformer or equipment terminal pads. HYSTACK™adapters are tin-plated, high conductivity aluminum to provide optimum corrosion resistance. Only three sizes accommodate terminals from 250 kcmil through 1000 kcmil to help keep costly inventories to a minimum. Features & Benefits • For use on terminals made from copper or aluminum material • Designed specifically for stacking standard terminals; uses include: • Place the stacking adapter on the mounting plate and a terminal on top of the stacking adapter and bolt down • Placing a stacking adapter on a terminal pad that will be mounted to a bus bar or mounting plate and a terminal on top of the stacking adapter, and bolt down • May be used with standard NEMA two and four hole terminals; to stack four hole NEMA terminations use two stacking adapters assembled side-by-side • Only three sizes necessary to accommodate terminals from 250 kcmil through 1000 kcmil, minimizing inventory requirements • Stacking adapters are clearly marked
