It is a radial circuit as he only disconnected one line conductor (R1) and also you can have more than one socket outlet on a radial but the R1+R2 readings will rise and fall depending on which direction you test whereas a ring circuit should be the same reading at each socket outlet.....but you've probably got this by now.
are you not testing polarity to the neutral, how do i know that the earth and line are connected to the correct terminals at the socket ?
Title is a bit misleading, I was hoping to see the test of a Radial circuit, not a Ring Final Circuit.
