Maximum 9 cables routed horizontally in direct contact with one another on a cable rack
Current-carrying capacity of PVC-insulated, 3-wire copper and aluminum cables with a maximum permissible conductor
temperature of 70°C at an ambient temperature of 40°C according to IEC 60364-5-52
With higher amperages, cables must be connected in parallel.
Note:
The recommendations for the North American market in AWG or MCM must be taken from the appropriate NEC
(National Electrical Code)/CEC (Canadian Electrical Code) standards.
5.4.3 Grounding and PE conductor cross-section
The PE conductor must be dimensioned to meet the following requirements:
· In the case of a ground fault, no impermissibly high contact voltages resulting from voltage drops on the PE
conductor caused by the ground fault current may occur (< 50 V AC or < 120 V DC, IEC 61800-5-1, IEC 60 364,
IEC 60 543).
· The PE conductor should not be excessively loaded by any ground fault current it carries.
· If it is possible for continuous currents to flow through the PE conductor when a fault occurs, the PE conductor
cross-section must be dimensioned for this continuous current.
· The PE conductor cross-section should be selected according to EN 60 204-1, EN 60 439-1, IEC 60 364.
