Ive a couple of queries about the AM2. Having tried twice now I failed the c1 safe isolation and even failed part of it that I passed the first time doing the same thing. When isolating the luminaire o the 3 phase board I asked permission then opened the breaker and locked it with a sign on and put the key away. I took the board cover off and proved the test meter then checked L-N, L- E and N-E then reproved ithe meter. Then I replaced the board cover and used the step provided to remove the luminaire cover. Proved the test meter and checked L, N E at the fitting in the same sequence as before and with each wall switch in a different position the reproved. I replaced the luminaire cover. I did the same for the 3phase DOL starter but using the 10step sequence for testing and by replacing covers on the board in the same way. To isolate the whole board I did the same but just one the main breaker using the 10step sequence then replaced the cover. I aslo failed the instal on the data section. I fitted it all but when testing began I realised line 1 and 6 didnt light up the meter. I redid both and they didnt work and redid them again after getti g line 1 to light up but not 6. I asked the examinor who did the same and then said the face plate was faulty so not to worry about it and he would note that on the exam notes so i left it as he instructed. Any ideas? Cheers
