Number of cables Seated in Cable Duct Wall fixing or Cable trough Cable tray
1 1.00 1.00 1.00
2 0.80 0.85 0.87
4 0.65 0.75 0.78
6 0.57 0.72 0.75
9 0.50 0.70 0.73
The total current included for using Table 1 should be the maximum rated current for the machine divided by the
product of the different correction factors. Other correction factors may also be applied ; consult the cable
manufacturers.
Calculation : Example
• The machine has a rated current of 60 A.
• The ambient temperature is 45 °C ; Table 2 gives a correction factor of 0.91.
• Rubber cable insulant : Table 3 gives a correction factor of 0.92.
• The cable is fixed directly to the wall (Column C), with 2 cables side by side. Table 4 gives a correction factor of
0.85.
