6.4 Connecting the mains supply
IEC 60364‑5‑52:2019 Section 524 makes recommendations for sizing the neutral conductor.
If no more precise information is available, the standard recommends dimensioning the
neutral conductor for 1.45 times the current-carrying capacity of the line conductors.
Fire caused by neutral conductor (N) overload
The neutral conductor can heat up due to the load from harmonic currents and cause a fire.
• Consider the harmonic currents when dimensioning the neutral conductor.
Electric shock caused by PEN conductor overload
In TN-C supply networks, the protective function of the PEN conductor can be adversely
affected by exposure to harmonic currents.
• Consider the harmonic currents when dimensioning the PEN conductor.
