In addition to the design of the building feed, e. g. a transformer-multiple feed, the design process also involves the design of the conductor cross-sections of the protective conductors and the protective bonding conductors of the earthing system in accordance with IEC 60 364-5-54.


In this webinar, we look at three different examples of how to construct the earthing system of a transformer multiple feed and estimate the largest possible fault currents over the protection conductors and protection bonding conductors. The conductor cross-sections are then determined using an example.



  • Regulations and standards
  • Examples of Transformer multiple feedin's
  • Estimation of maximum fault current over protective conductors and protective bonding conductors
  • Dimensioning of protective (bonding) conductors on an example


  • Basics of electrical engineering


We are looking forward to meeting you in the event!
