Anyone know what this test is? It is listed in the same column beside the insulation resistance tests on the installation test record sheet that needs to be completed by registered electrical contractors in Ireland.
The following test shall be carried out in order to detect erroneous connections between circuits: For each circuit, its protective device shall be switched off and an insulation test in accordance with Table 61A applied between phase conductors of that particular circuit and all other phase conductors.
Note 1: This is an additional test to those specified in CENELEC HD 384.6.61:1992 Note 2: All loads in the circuit under test must be disconnected e.g. appliances switched off, lamps removed.
So while it might spot the old 'one leg of a ring and the immersion connected to the ring fuse, and the other leg of the ring connected to the immersion fuse', it wouldn't necessarily spot (the more common?) borrowed neutral?
