Primary cabling
The primary cabling is cabling in the LAN area. It supplies the secondary cabling of several buildings. (All information without guarantee)
Switch-off behaviour
The shortest cable route should always be selected for installation. Cable runs that are too long limit the required tripping current in the event of a fault. This can delay or prevent switching off. The maximum cable length that can be used between the power supply and the end device depends on the following criteria: Maximum current of the power supply, internal resistance of the circuit breaker, line resistance. The cable resistance depends on the cable length and the conductor cross-section. (All data without guarantee)

Rated voltage
The rated voltage is the value of a voltage that is specified by the manufacturer for a component, device or piece of equipment and to which the operating and performance characteristics relate. The term "rated voltage" has been used in electrical power engineering since 1981 in order to better clarify differences to the nominal voltage in the standards. The rated voltage is greater than or equal to the nominal voltage and specifies the maximum value of the electrical voltage in normal operation. (All data without guarantee)
Rated current
Current of a device or equipment for which the device or equipment is specified by a standard or by the manufacturer. As a rule, the value of the current resulting from the rated apparent power and rated voltage, forexample, the current specified by the manufacturer (preferably at an ambient temperature of 40 °C) that a connector can carry continuously. The rated current flows simultaneously through all its contacts, which are connected to the largest possible conductors. The upper temperature limit is not exceeded. (All data without guarantee)
