Earth Electrode

This webinar looks in detail at one particular change to Amd2 of BS 7671 that may pass many by. Regulation 411.4.2 now recommends that an additional connection to Earth by means of an earth electrode is made to the main earthing terminal.  

We will consider why this change has been made and what other requirements need to be considered where such an earth electrode is installed.
