    Neutral earthing

    Been familiarising myself once again with SANS 10142 with regards neutral earthing.

    Couldn't help but had a little chuckle when reading 7.16.4.5.

    Is that regulation really necessary ?

      To save folk looking up the clause:
      7.16.4.5 The neutral shall not be earthed beyond any earth leakage unit.

      I can imagine how that conversation went in the SANS committee:

      Derlyn: Is that regulation really necessary ?

      Cecil: If we don't put it in, some idiot will f. it up and then blame us for their f-up.

          It's the same as saying .... " the live should not be connected to the neutral or earth anywhere on the installation. 😂😂

              I agree - Sometimes people don't think and bear in mind that some municipalities insist on an Adit unit when the supply is greater than 300KVA - The Adit unit may not pick up the neutral earth bridge due to it being set a lot higher than 30ma
