Figure 4-4 Protective conductor connection, cabinet with mounting plate / equipotential bonding
surface
The protective conductor connections must be dimensioned as follows:
Table 4-1
Conductor cross-section for copper protective connections
Line supply cable in mm² Copper protective connections in mm²
Up to 16 mm² The same as the line supply cable
From 16 mm² to 35 mm² 16 mm²
From 35 mm² 0.5 x line supply cable
For materials other than copper, the cross-section should be increased so that as a minimum,
the same conductivity is attained.
