  • 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 Specifications” noted are suitable for achieving a SCCR of 10,000A . (the default rating of terminal blocks).
  • Enclosure size – For SCCR’s greater than the default of 10KA, the minimum enclosure size is 16x12x6. When using the default rating, there are no enclosure limitations other than proper fit of the product.
