4 ELECTRICAL CONNECTION

4.1 Conditions for the electrical connection

Specifications for the sub-distribution:
• Each charging point must have its own supply line
with appropriate fuse protection.
• All versions of the wallbe Pro require a suitable cir-
cuit breaker and residual current circuit breaker.
• All variants of the wallbe Pro require a suitable re-
sidual current circuit breaker. Since the wallbe Pro
already has a DC fault detection > 6 mA, you do not
need a cost-intensive RCD type A (EV) or type B.
• If possible, use an overvoltage protection in the
sub-distribution.
Usable cable cross-sections:
• Use the cable cross-sections given in the table. If you
require larger cable cross-sections, please specify
them when ordering or contact us.
• When using a rigid cable, a maximum cross-section
of 10 mm² is possible with the wallbe Pro, 22 kW,
while only 6 mm² is possible with a flexible cable.
