OSG pages 67 to 71, is dealing with cpc continuity and ring final circuit continuity tests. the cpc continuity is basically to measure the R1+R2, and at the same time the continuity of the cpc and phase wires. The ring final circuit continuity test seems to do the same thing but in three steps configuration, the part that I'm interested in is when the phase is connected to the cpc. What is the difference between this test and the cpc continuity test, I looked in the BS 7671, but it did not make it more clear. (the testing process itself is no problem) I'm sure that i miss something here.
Can someone explain.
thanks
