The total current included for using Table 1 should be the maximum rated current for the ma-
chine 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 fi xed directly to the wall (Column C), with 2 cables side by side. Table 4 gives a
correction factor of 0.85.
60 A
Total current : ----------------------- = 84 A
0.91 x 0.92 x 0.85
Taking Column C in Table 1 (wall fi xing), we obtain a minimum cable section of : 3 x 25 mm².
