  • #2: Decoding Article 625: EV Charging Equipment Installation Requirements
    2025/04/21

    In this episode, we delve into the National Electrical Code (NEC) Article 625, focusing on the Ground-Fault Circuit Interrupter (GFCI) protection requirements for Electric Vehicle Supply Equipment (EVSE). We explore the key distinctions between personnel protection requirements and GFCI protection requirements. Whether you’re an electrician, contractor, or EV owner, this episode provides essential insights into ensuring safe and code-compliant EV charging setups.

    Key Topics Include:
    - GFCI Protection
    - EVSE Personnel Protection
    - EVSE GFCI Protection
    - Implications of hardwired vs cord-and-plug connected EVSE
    - EVSE Equipment Maintenance

  • #1: Fault Current Fundamentals - Understanding SCCR, Common Issues & NEC Compliance.
    2025/03/18

    In this episode of CQD Spotlight, Kyle Krueger, NECA - Exec Dir, Codes and Standards and Thomas Domitrovich, Eaton-Director, Codes and Standards, dive into the critical concepts of Short Circuit Current Ratings (SCCR), available fault current, and interrupting rating requirements as outlined in the National Electrical Code (NEC). From HVAC equipment and elevator control panels to fault current calculations and series ratings, we cover real-world scenarios that electrical contractors, inspectors, and engineers face daily.

    🚨 Key topics include:
    ✔️ Understanding the difference between SCCR and interrupting ratings
    ✔️ HVAC equipment compliance and why it often causes last-minute headaches
    ✔️ Elevator control panels – why they can be problematic and how to navigate regulations
    ✔️ Fault current calculations and their impact on electrical system safety
    ✔️ Solutions – including conductor length, 1:1 transformers, fusible disconnects, and series ratings
    ✔️ The importance of collaboration between electrical and mechanical teams to prevent installation issues

    This episode is packed with real-world insights and practical advice to help you navigate SCCR challenges and avoid costly mistakes. If you've ever faced last-minute compliance issues with available fault current ratings, this is a must-watch!
