Notes on the table:
We do not know the cable type used by you, its length
and the installation conditions (temperatures, grouping).
The table above can therefore only be regarded as a
guideline.
The supply cable cross-sections given in the table
comply with VDE 0298, part 4 - table 13, column 7.
(Rubber hose line at 30 °C/86 °F and max. line length of
50 m). In the case of differing conditions (line length,
temperature and grouping), establish the cross sections
in accordance with DIN VDE 0298, part 4 or BS7671
taking into account the cable type.
Important
If local regulations are stricter than the values
specified above, observe the stricter regulations.
