- For use with conductors prepared with listed connectors such as single hole compression/crimp lugs or listed ring, fork or spade terminals. 

- Conductor size, ampacity, temperature rating and type are dictated by the ratings of the listed lugs utilized and applicable code requirements. 

- For use with Flexibar (flexible busbar) when prepared appropriately. 

- End positions (that mount the busbar to the insulator ends) are intended to be used as terminal positions. 

- It is NOT recommended to stack Lugs with Flexibar on the same stud position(s). 

## Short Circuit Current Ratings (SCCR) 

- The suitable wire/flexibar ranges are limited to the table values only for achieving the SCCR ratings in excess of the default rating of 10,000A. 

- Other conductor combinations within the “Terminal Specifications” noted are suitable for achieving a SCCR of 10,000A (the default rating of terminal blocks). 

- Enclosure size – Investigated with a minimum 24x20x8 Enclosure.  Use in smaller enclosures is subject to end use evaluation.

## Installation & Accessories 

- Mounting (Panel): 

   - Recommended 3/8” fastener with flat washer (max diameter 1”). 

   - Recommended torque for mounting fastener: 50-100 in-lbs (5.6-11.3 N·m). 

- Covers: 

   - Screw-on covers available upon request. 

   - For specific part numbers, see the table on page four. 

   - Covers are clear Acrylite® that come with a peel-off protective film to prevent scratches. 

- Tools needed: 

   - Socket Driver 3/4” for 1/2” Hex Terminal Nuts, or 9/16” for 3/8” Hex Terminal Nuts. 

   - Phillips Drive #2 for Cover Mounting Screw. 

- Safety Guidelines: 

   - Assure all washers and nuts are secured on any unused studs. 

   - Use appropriate/specified hardware (washers & nuts). 

   - Accessory Cover (Optional) is not intended to provide insulation for electrical spacings. 

   - • When stacking lugs: 

      - Wider lugs should be mounted first, with smaller lugs following on top. 

      - Assure Tangs are in contact with the busbar or each other, and barrels are not interfering.
