Personnel who work in or on industrial control panels (ICP) while they are energized may have an increased risk of an arc flash event. Providing optimum protection to these workers requires attention to providing adequate Short Circuit Current Rating (SCCR) for the panel, enhanced component short circuit protection and minimizing arc flash energies within the panel.
This 2-part webinar will:
- Review the importance and safety implications of adequate SCCR for ICP.
- Provide an overview of low voltage UL listed current limiting fuses.
- Show what fuses are best for arc flash mitigation and how to ensure the lowest incident energy for workers exposed to the arc flash hazard.
- Review strategies for improving short circuit safety and minimizing risk
- Show what current limiting fuses can provide Type 2 protection.
- Review NEC SCCR requirements for installation of panels.
- Demonstrate how UL 508A Supplement SB is used to determine panel SCCR.
- Give examples of how the use of current limiting fuses can increase component SCCR and panel SCCR.
