Appendix E Line and Load Cable Sizes
(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 (that is, 8 kV is not commercially available in many areas of the world, therefore Rockwell Automation
provides an 8 kV (minimum rating) and a 15 kV rating, when applicable. Enclosure openings accommodate the thicker
insulation on the higher-rated cable. IEC ratings show the equivalent to the NEMA sizes. The exact cable mm
2
size that is
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 (for example,
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 that are shown do not account for the size of the conduit hub.
Verify size of conduit hubs against the “Drive enclosure openings” shown.
