same material. If the materials are different, ensure that the conductor of the PE cable with a
proper cross-sectional area 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.
● The cable diameter must comply with local cable standards.
● The factors that affect cable selection include the rated current, cable type, routing mode,
ambient temperature, and maximum expected line loss.
