IEC60364‑5‑52:2019Section524 makes recommendations for sizing the neutral conductor.
If no more precise information is av
ailable, the standard recommends dimensioning the
neutral conductor for 1.45 times the current-carrying capacity of the line conductors.
WARNING
Fire caused by neutral conductor (N) overload
The neutral conductor can heat up due to the load fr
om harmonic currents and cause a re.
• Consider the harmonic currents when dimensioning the neutral conductor.
WARNING
Electric shock caused by PEN conductor overload
In TN-C supply network
s, the protective function of the PEN conductor can be adversely
aected by exposure to harmonic currents.
• Consider the harmonic currents when dimensioning the PEN conductor.
