SCCR INFORMATION:
The requirements of the National Electric Code (NEC) and UL 508A 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.
Many of our recognized and listed power 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 (fuses or circuit
breakers). UL 508A does allow default SCCR for power distribution blocks of 10,000A with no additional testing.

GENERAL INFORMATION
FLEXIBLE STRANDED WIRE INFORMATION:
Traditionally, power blocks and fuse holders have been evaluated for use with rigid (Class B & C) wire only.
The majority of our products have been evaluated for use with flexible stranded wire classes such as Class
G, H, I (DLO) and K per UL 486A-B. This enables customers to be UL and NEC compliant while using flexible
classes of wire without the use of crimp type terminals. We also supply a range of studded products to
allow for the use of crimp terminals, which are recommended for larger wire sizes (greater than #1 AWG).
Flexible stranded wire classes differ in that they also bring
additional considerations to address such as an increase in wire
diameter and the number of strands per a given wire size. The
photo to the right shows two 250 kcmil wires of different classes.
The one on the left is the traditional Class B with 37 strands. The
one on the right is a finely stranded Class K. Although they are
the same wire classification of 250, you can see the Class K is
larger in diameter. This illustrates the need to specify a terminal
to accept a larger standard wire size. The table below shows the
increase in strand count per each wire size.

DESCRIPTION IMAGE
The BFPB Series is a single pole design that consists of a series of
stud fasteners to allow you to terminate various combinations of
crimp lugs or exible bus bar with one conguration. The series is
ideal for use with exible stranded wire terminations or large and
abnormal wiring combinations.
The EPB Series are enclosed versions of our traditional power
block congurations. This series consists of a modular single pole
design that provides touch proof protection for splicer and distribution connector styles.
Splicer and distribution power blocks are our traditional NEMA
style offering. Splicer power blocks provide the same number
of wire inputs as outputs, and distribution power blocks provide
multiple load outputs per each incoming wire.
The HVPB series are high voltage (1500 AC/DC) versions of our
traditional power block congurations. This series consists of a
modular single pole design for splicer, distribution and studded
connector styles.

bare wire terminals with the stud to terminate crimp lugs or bus
bar to distribute power.
Miscellaneous power blocks are part of our traditional NEMA
style offering. These power blocks provide tapped holes or quick-

power.
STANDARDS:
Regal’s Marathon® Special Products power blocks are either UL recognized or listed. Most have either CSA
certification or cUR recognition for Canadian customers, as well as compliance to CE (Component IEC 60947-7-1).
RECOGNIZED power terminal blocks comply to UL 1059 and CSA C22.2 No. 158. All of our power blocks
meet the 600V spacing requirements for application classes B & C and some Class A (135s): See General
Information (pg 4) for class descriptions.
LISTED power distribution blocks comply to UL 1953. These are all rated 600V and are intended to be used
on the load side of service equipment in accordance with the National Electrical Code, NFPA 70. Listed
power blocks provide feeder circuit terminal spacing requirements of UL508A.
