Table 4

(B2, C and E correction factors for cable grouping)

	B2	C	E
Number	Seated in	Wall Fixing	Cable
of cables	Cable Duct	or Cable Trough	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 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.
