What it is
Panduit’s Bob Voss explains UL 1400-1, the first standard developed specifically for Fault Managed Power Systems, and how Panduit became the first company to earn certification. The interview covers system-level safety requirements including fault detection, power limitation, and thermal management, plus the impact on project timelines and AHJ approvals.
Why it matters
UL 1400-1 certification directly addresses code/AHJ friction by providing independent verification of fault detection and energy limitation capabilities. For electrical contractors and facilities teams, UL-listed FMPS products simplify permitting and inspections, leading to faster approvals and fewer project delays. The standard sets testable safety thresholds for Class 4 power that reduce fire and electrical hazards during installation and operation.
