Marathon 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.

Marathon’s Power Distribution Blocks are standard products that have been used in

electrical control panels for over 35 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.

Marathon’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.

Marathon's new Power Distribution Blocks (UL File # E309401) are listed to UL 1953. The

feeder spacing requirements of UL508A are achieved with these blocks.

UL 1953 Listed Power Distribution Blocks

meeting

spacing requirements for UL 508A service entrance

clearances. Short-Circuit Current Ratings (SCCR)

with fuses up to 100,000A and circuit breakers up

to 65,000A.

UL 1059 Recognized Power Terminal Blocks

with

SCCR ratings with fuses up to 200,000A and circuit

breakers up to 65,000A.

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.
