Note
Recommended connection cross-sections
The recommended connection cross
-sections are determined for copper cables at 40 °C
(104
°F) ambient temperature and cables with a permitted operating temperature on the
conductor for 70
°C (laying type C - factor for bundling 0.75 considered) according to
DIN
VDE 0298-4/08.03).
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 x S
Recommended cross
-sections:
•
MS ≥ S
