Power Distribution Blocks with
SCCR and Feeder Spacing
Short-Circuit Current Ratings
and Feeder Spacing
SCCR Information:
The requirements of the 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 Recognized and Listed Power Blocks 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 protec-
tion device (fuses or circuit breakers). UL508A does allow default SCCR for Power Distribution Blocks of 10,000A
with no additional testing.
For detailed SCCR product information, please visit www.marathonsp.com/PDFs/SCCR.pdf
Feeder Spacing/Adapter Plates for Feeder Spacing:
Recently, the National Electric Code (NEC) and UL508A began requiring that Power Blocks used in Feeder Circuits must
carry voltage spacing greater than the traditional Industrial Control requirements. Marathon offers Power Blocks solutions
that meet feeder spacing requirements.
• Marathon’s Listed Power Distribution Blocks cover a range of small to large wire termination capabilities and meet
the requirements for use in feeder circuits per UL508A up to 600V.
• We also offer a line of adapter plates for Marathon’s Recognized Power Blocks that allow the customer to mount
three single-line Power Blocks on a base which assures the requirements of feeder spacing are met.

Power Terminal Blocks
Power Blocks
General Information:
Barrier Style Power Terminal Blocks are available in eight sizes. They are identified by the first three digits of the catalog number. The
140, 142, 143, 144 and 145 series are manufactured with general purpose phenolic rated at 150oC. The 141, 132 and 133 series
are manufactured with high impact thermoplastic rated at 125oC.
Conductor Opening Diameter of Opening
* Enclosed blocks have larger openings (see page 42)
Ratings and Standards:
The voltage ratings of terminal blocks are based upon the minimum spacing between electrically conductive parts line to line through
air and over surface and line to ground through air and over surface.
Class A
Service equipment including deadfront switchboards, panel boards, service entrance devices.
Class B
Commercial appliances including business equipment, electronic data processing equipment and the like.
Class C
General industrial and machine tool controls which can be further defined as equipment falling under
UL 508. Ratings based on UL 1059 may be higher in some cases depending on application.
Applications:
Designed for use with solar, wind, alternate energy, transportation, heating, air conditioning and refrigeration, elevator systems,
material handling equipment, control panels, motor control, switchgear and any area where power needs to be distributed to more
than one load.
