 The specifications are valid only if the conductors of the PE cable and AC power cable use the same
material. If the materials are different, ensure that the conductor cross-sectional area of the PE cable
produces a conductance equivalent to that of the cable specified in the table.

The specifications of the PE cable are subject to this table or calculated according to IEC 60364-5-54.
