3 The differences are whether the Power Distribution Blocks are enclosed or not, and whether they areUL1953 Listed PDBs or UL1059 Recognized PTBs, whichhave different minimum spacing requirements. The table onthis page can assist in the selection of the right series foryour application these are important?Assembly short-circuit current ratings (SCCRs) are nowrequired in the 2008 NEC and UL 508A Listed IndustrialControl Panels. Marking the SCCR on Industrial ControlPanels (NEC ), Industrial Machinery ElectricalPanels (NEC (A)), and HVAC equipment (NEC (B)) is now required by the National Electrical or PTBs not marked with a SCCR, typically are theweakest link and may limit an assembly to no more than 10kASCCR.

4 The PDBFS and PDB Series have increased spacingrequired where used in feeder circuits in equipment listed toUL508A (UL1059 PTBs must be evaluated for proper spac-ings). Also, for building wiring systems, the PDBFS Seriesand PDB Series Power Distribution Blocks can be used tomeet the new 2008 NEC requirements in section (B)for PDBs in **PanelsPanelsULNEC PageULEnclosedSCCR*1 AirUL 508 AUL (B)2 SurfaceBranchFeeder(RequiresCircuitCircu itUL 1953)Series PDBFS295UL 1953 ListedYes YesYesYesYesYesYesYe sSeries PDB296UL 1953 ListedNo**YesYesYesYesYesw/optionalcover Selection Table IP20 finger-safe under specific conditions, see datasheet 1149.
