Use Edison Finger-safe Power Distribution Blocks to manage your power distribution needs, from splitting primary power circuits into a variety of branch circuits to providing a fixed junction tap-off point.- Modular design to select and configure the number of poles required by each application
- Engineered to allow copper conductors and maintain an SCCR rating of 200kA
- The perfect solution to today's power circuit wiring requirements

Edison UL 1953-listed enclosed power distribution blocks are suitable for use in UL508A panels to manage power wiring and branching, as well as provide tap-off points. DIN-rail mounted finger-safe blocks are enclosed to prevent accidental contact with live wiring, offer a high short-circuit current rating of 200kA, and are available in a range of amperage ratings.

We offer distinctly different styles of short-circuit current rated (SCCR) power distribution blocks (PDBs) and terminal blocks (TBs) to match different application needs. The differences are whether the power distribution blocks are enclosed or not, and whether they are UL1953 Listed PDBs or UL1059 Recognized TBs, which have different minimum spacing requirements.

- Assembly short-circuit current ratings (SCCRs) are now required in the 2005 NEC® and UL508A Listed Industrial Control Panels.
- Marking the SCCR on Industrial Control Panels (NEC® 409.110), Industrial Machinery Electrical Panels (NEC® 670.3(A)), and HVAC equipment (NEC® 440.4(B)) is now required by the National Electrical Code.
- Power distribution blocks or terminal blocks not marked with an SCCR are typically one of the weakest links and may limit an assembly to no more than 10 kA SCCR.
- The EPDB series and HPB series power distribution blocks have increased spacing required where used in feeder circuits in equipment listed to UL508A. The PB series UL1059 terminal blocks must be evaluated for proper spacing.
- Also, for building wiring systems, the EPDB series and HPB series power distribution blocks can be used to meet the 2005 NEC® requirements in section 376.56(B) for power distribution blocks in wireways.
