@chiplard No! ambient temperature is for cable calculations.
So what is Table 2E in the OSG for then?

@chiplard No! ambient temperature is for cable calculations.
OSG is the mini BS7671Quote from Appendix 2 of OSG - first paragraph.
The tables in this appendix provide max permissible measured earth fault loop impedences Zs............... .............The values are those that must not be exceeded in the tests carried out under 10.3.6 at an ambient temp of 10 deg C. Table 2E provides correction factors for other ambient temperatures.
What is that trying to explain then?
