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