HANDBOOK

The feeder cable sections mentioned in our literature are given only as a guide.

To obtain a value perfectly suited to your own application and which takes account of the differ- ent correction factors in respect of your plant, refer to the tables below.

Table 1 (in accordance with EN Standard 60204-1)

Values given for :

-Cable with copper conductors

-Cable with PVC insulation (for other insulants see Table 3)

-Ambient temperature 40 °C max. (for others see Table 2)

-Three-phase cable under load without including starting currents

-BT / C/ E cable layout.
