Methodology
Every figure on this page is a safe working load with the standard’s safety factor already applied. Loading depth is the internal usable cable fill depth of the side rail.
NEMA classification per NEMA VE1-2009: 20AA < 20A < 20B (increasing capacity).
Test reports and vendor prequalification documents are on the certifications page. For a load case outside these tables, send it to our engineering team.
