Title
The power losses on the power supply line must be less than +/- 10 percent of the rated power in
accordance with IEC 60038 and local standards. Hence, the cable sections or line length must be
reassessed by professional and qualified personnel in accordance with maximum power loss regulations.
Also, when dimensioning the power supply line, observe the possible reduction factors and the increased
environmental temperatures inside the connection area of the EV charger. See the temperature rating of the
supply terminals. Under certain circumstances, this can increase the cable cross-section and change the
temperature resistance of the power supply line.
Professional and qualified personnel must define the types of RCD and circuit breaker.
When dimensioning the line circuit breaker, the increased ambient temperatures in the control cabinet
must also be considered. Under certain circumstances, this can make a reduction of the charging current
specification necessary in order to increase the system availability.
Figure 7 . The Green Motion Building EV charger wiring diagram
Each EV charger must be connected via a separate RCD/fault-current circuit breaker. No other consumers
may be connected to this circuit.
The circuit breakers and the power cable minimal cross-sections should be defined by professional and
qualified personnel.
During installation, other important issues such as “cascading” of RCDs and selection of a suitable line
circuit breaker must be considered.
