____ up the ends of the ____ final circuit conductors as L1, N1, E1, L2, N2 and E2. ____ the end to ____ resistance of each ring ____. The resistances for L1 L2, N1 N2 and E1 E2 loops are referred to respectively as r1, rn and r2. A ____ reading confirms that there is ____ circuit on the ring conductors under test. The ____ values should be substantially the same (within 0.05Ω) if the conductors are the same size. If the protective conductor has a ____ CSA the resistance r2 of the protective conductor will be proportionally ____ than that of the line and neutral loops, ____ for 2.5/1.5mm2 cable. If these ____ are not achieved then either the conductors are ____ identified or there is something wrong at one or more of the ____ in the accessories.
