## Short Circuit Current Ratings (SCCR) 

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

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

- Enclosure size – Investigated with a minimum 16x12x6 enclosure.  Use in smaller enclosures is subject to end use evaluation.
