By my understanding, the correct answer in the test only of existing CoC situation if there is no point already in place would currently be "N/A" under the current legislation.
The accessible earthing terminal is obviously applicable and the answer must be "Yes" for a 9.2.a CoC (new installation), as in that case the entire contents of SANS 10142-1 is applicable to the entire installation.
What is less clear cut to my mind is when it comes to a 9.2.c CoC (addition or alteration to an existing installation). Here the full code is applicable to the alterations and additions, but the section 5 "reasonably safe" standard applies to the existing balance of the installation.
