When you say "no reading" does your tester not carry out the test or is it a value of infinte resistance? Btw which tester are you using?
Check your instrument, test leads and adaptors for possible intermittent connections. Otherwise what you are claiming is that when connected in parallel the L & N (measuerd OK at 0.24Ω) both went open circuit at the same time. Also obviously the L/CPC reading was too high.
Think OP is referring to 'step 2' of RFC test, cross connection of live & neutral conductors to confirm correct connection of conductors at each outlet. According to his figures he should be obtain a reading of 0.12 ohms (0.24+0.24/4). Or have I misinterpreted both you & OP?hang on. in the op you say you're not getting a reading L1 N2 etc. well, you should not. you are cross connecting the L's and cpc's so you should only get readings between these. the N's are not relevant.
Making the assumption we are measuring 6242y cable?OP was your reading for r1+r2/4, 0.24, obtained at the CU ends. As Lucien said it's high, should be around 0.15ohms, although the reading for r2, should be around 0.40oms without parallel paths.
Try taking the socket outlet off and connect your probes directly to the cables.Gonna try again
