Class 1 appliance with no exposed metal work to connect test lead too
Former Community Member
OK 3rd problem class one appliance with no exposed metal work to connect test lead too how can I carry out the earth bond test given it is a class 1 appliance and not a class 2 appliance like this
In addition, the latest 5th Edition of the IET CoP for In-Service Inspection and Testing of Electrical Equipment makes it quite clear:
"10.5 The protective conductor continuity test
This test is required to verify the integrity of the protective conductor, especially the connection between the protective conductor and the accessible earthed metal parts of the equipment. This test should be carried out on equipment that relies on a connection with earth for its safety (protective earthing)."
That is, it is accepted that it's not possible to test to exposed-conductive-parts that are inaccessible without dismantling the appliance. From the perspective of recording the test, recording"Not Possible" (or electrician's "LIM" and a limitation note) would be advised I guess.
Whether a particular organisation, or their insurer, is happy with that approach is of course another question.
