And in the Waikato, from what I’ve seen, in the walls, it’s common practice for the thermal insulation installers to slice the batts in the middle, open up the insulation and slide it around the cables. Most of the N/S I see is PVC (probably because it cheaper the XLPE), so table 10. Thanks for the reply’s - The reason I say 40A MCB protection for a 16mm2 N/S is I’m using worst case scenario. So this is why most mains in a standard new home when given a 63A supply use a 16mm² single core N/S X-90 rated for partially surrounded

In terms of CCC, all the single core N/S I see is X-90 as it's XLPE so table 11 is the appropriate one to use, looking at Cu 54A for full and 86A for partially So although every case is different, normally partially surrounded can be achieved with some consideration
In regards to down walls insulation is normally pushed over the cable to one side and the cable becomes wedged between the lining and insulation making it partially surrounded.Īs per 3.4.3 of 3008, to be completely surrounded the cable has to be covered completely for more than 400mm As you know it's all about how you choose to run the cable and you definitely need to consider how the insulation is likely to be placed in regards to this. So yes we have to consider it but that doesn't mean it's going to be completely surrounded.
