(1) Cable sizes are based on overall dimensions of compact-stranded three-conductor shielded cable (common for industrial cable tray
installations). Maximum sizing stated accounts for minimum rated cable insulation requirements and the next higher-rated cable
(i.e., 8 kV is not commercially available in many areas of the world, therefore Rockwell Automation provides an 8 kV (minimum
rating) as well as a 15 kV rating, when applicable. Enclosure openings will accommodate the thicker insulation on the higher-rated
cable. IEC ratings show the equivalent to the NEMA sizes. The exact cable mm
2
size shown is not commercially available in many
cases; use the next smaller standard size.
(2) Minimum cable bend radius recommendations vary by national codes, cable type, and cable size. Consult local codes for guidelines
and requirements. General relationship of cable diameter to bend radius is typically between 7x...12x (e.g., if the cable diameter is 1
in. [2.54 cm] the minimum bend radius could range between 7...12 in. [18.8...30.48 cm]).
(3) As cabling methods can vary widely, maximum cable sizes shown do not account for the size of the conduit hub. Verify size of
conduit hub(s) against the “Drive enclosure openings” shown.
