12.2 Connection cable
Notice
The cable cross-section can be calculated using the following formula:
A = 0.0175 x L x P/(f
k
x U
2
)
A = Cable cross-section in mm
2
0.0175 = Specific electrical resistance of copper [Ohms x mm
2
/m]
L = Cable length (plus wire + minus wire) in m
P = Power conducted by the cable, in W
f
k
= Power loss factor (generally 1.5 %) = 0.015
U = Voltage, in V
