yep. IR testing is for the circuit/s alone. should never IR test with RCDs or any other sensitive equipment connected.
Well unless your doing a PIR of course..Test method 2..

i would hope he's clipping to the bare ends of the stripped conductors.

The insulation resistance measured with the test voltages indicated in Table 61 shall be considered satisfactory if the main switch board and each distribution circuit tested seperately, with all it's final circuits connected but with current using equipment disconnected, has an insulation resistance not less than the appropriate value given in table 61.
Did you split the ring and then retest as 2 radials ?
The same thing can apply to CPCs - you IR test L-CPC with the conductors disconnected from the board - >299...........but what if the 'line' conductor has been snagged on some earthed metalwork somewhere - again, it's not gonna show up.
