I think I may have asked this question a while ago but not sure on what the answer was and it's come up again at our monthly tool box talk.

When doing a Minor works for an additional spurred socket or extra light fitting on a circuit, should the R1+R2 measurement be taken from the protective device or the socket/fitting you have spurred from?
 
Why would you be recording the R1+R2?
What is the purpose behind it?
You nee to ensure that the circuit you are adding, altering etc is correct, if the RFC you are adding a spur to, and the R1+R2 was suspect, indicating that maybe it is not wired correctly, then adding a new spur may not be the best option, that's how I read it Spin.
 
18th Ed MWC asks for continuity readings as well as Zs.
Agree Mate, but the question the OP posed, or at least I think this what he is asking, is would you need to take continuity readings of just the new cable installed, or the continuity of the new and existing circuit, my thoughts are post 6.

I think Spin knows the answer but is trying to help the Trainee.
 
but it's not just the form, it's to confirm that there is a cpc to each point
