100 Van Camp Road P.O. Box 468 Bowling Green, OH 4402 Standard Power Distribution Blocks With High Short-Circuit Current Ratings offers 600 Volt Power Distribution Blocks with high SCCR s in response to new 2005 NEC and UL508A marking requirements The requirements of the 2005 National Electric Code (NEC) and UL508A now require many electrical panels to carry a Short Circuit Current Rating (SCCR). Analyzing the SCCR of individual components and overcurrent protection devices is a method of determining the SCCR of an electrical assembly. s Power Distribution Blocks are standard products that have been used in electrical control panels for over 5 years. These blocks have now been tested and approved for higher SCCR. The higher ratings are based on proper wire sizes and the appropriate circuit protection device. UL508A does allow default SCCR for Power Distribution Blocks of 10,000A with no additional testing. s Power Distribution Blocks (UL File # E62806) are recognized under UL Standard 1059 and have been investigated by UL for Short-Circuit Current Ratings (SCCR) as described in the UL Guide Information for category XCFR2; Terminal Blocks-Component. 's new Power Distribution Blocks (UL File # E09401) are listed to UL 195. The feeder spacing requirements of UL508A are achieved with these blocks. UL 195 Listed Power Distribution Blocks meeting spacing requirements for UL 508A service entrance clearances. Short-Circuit Current Ratings (SCCR) with fuses up to 100,000 ka and circuit breakers up to ka. Power Distribution Block with hinge cover UL 1059 Recognized Power Terminal Blocks with SCCR ratings with fuses up to 200,000kA and circuit breakers up to ka. For rating details see detailed data sheets at www.marathonsp.com. These data sheets contain valuable product information including a photo of the product, technical drawings, short circuit current ratings, electrical and mechanical ratings and agency approvals.
