Why do people twist CPC's?

The latest video from “Doctor Electric” on YouTube has really annoyed me(titled "Best ZS Ever)!

What is it with these YouTube “Sparks” that they think they can just start up a channel and think they're god?

On this video Doctor Electric shows viewers how to twist the CPC's to get a better ZS!! UNBELIEVEABLE!!!

    Did you notice, in the Draft for Public Comment of Amendment No. 2, Regulation 543.7.1.204 (independent termination where two protective conductors are used to provide reinforced earthing for high protective conductor currents) is proposed for deletion?

     

    In a word, no.

    And there’s me having been putting ring circuit CPCs into adjoining earth bar terminals when there’s space with the conductors tied together with cable ties, as I do with line and neutral to make it clear which pairs go together.

    All these little habits and rituals I have created for myself being an anorak are going to prove futile ?

    So, to be clear, current BS 7671:2018+A1:2020 does require two independent terminals for high protective conductor currents where (up to 10 sq mm CSA) you use either a ring final circuit cpc, or a second cpc in the form of a ring, to meet the requirements.

    Of course, I'm just pointing out what was in the DPC for AMD2:2022 - we will have to wait until 2022 to find out what the final version will be.
