Nominal current-carrying capacities
Table 1 shows the current-carrying capacities and voltage drop detailed for every cable. Current-carrying capacities, in amperes, are calculated according to UNE 211435 and for the following conditions:
- Open air installation: three single-core cables in contact and ambient temperature of 40 °C with adequate ventilation (supported by cleats and hangers or on perforated tray).
- Buried installation: three single-core cables in contact directly buried at depth of 0,7m ; 25 °C of ground temperature and soil thermal resistivity of 1,5 °K·m/W.
- In all cases it is supposed a three-phase circuit. Voltage drop is the maximum that may occur. It is calculated for the maximum service temperature and for cos = 1.

Short-circuit current-carrying capacities
The maximum short-circuit current that a cable can withstand depend on the time of reaction of the protection elements installed in the line. The maximum current-carrying capacity in a short-circuit accident, for a specific type of cable, is the result of multiplying the cross section of the cable for the values shown in table 2. These values are taken from IEC 949.
