Hi,
Im just having a read through 3012:2019 to preempt some of the proposed changes coming for Domestic Construction SwitchBoards (BTS).

J3 (h) & (i) are self explanatory (Board must be 1200mm from ground and fixed into position with 2 stays) BUT is the 3.0m pole (for underground mains) mandatory or a guideline only? (Table J1)

Thanks

currently "3012" is not cited as mandatory [ESR 25].
I am not aware of any suggestion that this will change when the citation in Schedule 2 changes to the newer edition.
That makes the entire document advisory.

App J is stated to be "normative"; and the effect of this is that it has the same status as the main text.
So a 'shall" statement in the appendix must be complied with in order to comply with the Standard as a whole.

However Table J1 has the word "typical" in the title; and nothing? in any clause makes any specific items on the Table mandatory,
so it can't be anything more than guidance.
