To order blocks with cover installed, add “CH” to end of part number - if ordered with cover installed, blocks are UL Recognized
The requirements of the National Electric Code (NEC)
and UL508A now require many electrical panels to carry a
Short Circuit Current Rating (SCCR). These new Power
Distribution Blocks are listed to UL1953. The feeder spacing
requirements of UL508A are achieved with these blocks.
