4.5.4 TABLE 4 B2, C and E correction factors for cable grouping :
B2 C E
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
4.5.5 Calculation
The total current included for usint Table 1 should be the maximum rated current for the machine divided by the prod-
uct of the different correction factors. Other correction factors may also be applied ; consult 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 insuant : 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. The Table 4 gives a correction factor of
0.85.
Total current : _____
60A ______= 84A
...........................0.91x0.92x0.85..............
Taking Column C in Table 1 (wall fixing), we obtain a minimum cable section of :
3x 25 mm²
