Don't you still have to fill in a Generic Schedule of test results?No,like I say it is not a requirement to measure it on a EICR
Even though you have agreed limitations with the client etc.

Yes you fill in test results, as far as ADS is concerned you need the measured Zs for the circuits.Don't you still have to fill in a Generic Schedule of test results?
Even though you have confirmed limitations with the client etc.
It’s not a limitation, it’s not required full stop for a EICR but it’s not precluded either.sorry Im getting bit confused here wires crossed I think
You don't need a reading of R1+R2 for periodic inspection if you agreed that limitation with you client but there is a Schedule of test results ?
But the question has no information to state the cables will be running at 70C, nor the information (if any) to calculate what temperature it might be operating at.
What if it were XLPE SWA at 90C instead?
What if a long run of 16mm that would barely show any rise?
The examiners deserves a boll0cking for that.
It's my understanding that the values in the OSG are adjusted for temp which accounts for the difference you'll find in tables for max Zs etc....because the OSG is your go to while 'in the field' and BS7671 would be your go to when carrying out 'design'.Chris Kitcher does use 1.2 in his video and gives an explanation so yeah your right

so at a guess the mV/A/M values from OSG etc are actually at Max working temp already i.e 70°C
