Cable Dimensions and Tightening Torque
 ● Data and models recommended in this section are for reference only. 
The user selected cable diameter must not be larger than the terminal 
width in the following gures.
 ● Selection of IEC cables is based on:
 
–
Standards EN 60204-1 and IEC 60364-5-52
 
–
PVC insulation
 
–
40°C ambient temperature and 70°C surface temperature
 
–
Symmetrical cable with copper mesh shield
 
–
A maximum of 9 cables are allowed in a 
cable tray.
 ● For North America, the recommended cables in the preceding table must 
be copper wires rated 600 V, 75°C.
