Conversion factors for deviating ambient temperature, grouping, installation under the ceiling, multi conductor cables and insulated wires - see DIN VDE 0298 part 4.

¹⁾ The current ratings are valid for cables with concentric conductor, only for multi conductor versions
²⁾ For further installation methods – see DIN VDE 0298 part 4
³⁾ See DIN VDE 0298 part 4
⁴⁾ Not permitted for the installation on a wooden wall and not for application of the conversion factors, see DIN VDE 0298 part 4
