Note
Recommended connection cross-sections
The recommended connection cross
-sections are determined for copper cables at 45 °C
ambient temperature and cables with a permitt
ed operating temperature at the conductor of
°C (routing type C - factor for bundling 0.75 considered) according to DIN VDE 0298-
Protective conductor cross-section (S: Cross-section of the supply connection phase
conductor, MS: Cross-section of the external protective conductor):
Minimum cross
-sections:
S < 16 mm² → MS = S
16 mm² ≤ S ≤ 35 mm² → MS = 16 mm²
S > 35 mm² → MS = 0.5 × S
-sections:
MS ≥ S
