### The cable tray shall be selected to a NEMA VE 1 (metal) or NEMA FG 1 (fiberglass) load/span class whose rated working load equals or exceeds the design cable load at the actual support span, with deflection within the manufacturer's published limit. {note}
−### The NEMA load/span class is designated by a support span in feet (8, 12, 16, or 20 ft) and a working load letter (A = 50 lb/ft, B = 75 lb/ft, C = 100 lb/ft), so a 20C tray is rated 100 lb/ft on a 20 ft span; the class shall be selected from the manufacturer's load tables for the project's span and load. {note}

## A metallic cable tray system is a continuous metallic enclosure for the cables it supports, and NEC 392.60 requires it to be grounded and bonded so that it is electrically continuous and can carry fault current; the open construction does not relieve this requirement. {note}
−## The grounding and bonding of the cable tray system shall be coordinated with [[sync/grounding-and-bonding]]. {note}
