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.
- Cable with rubber insulation : 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.
