I have my AM2 exam tomorrow and I have a query about where to actually isolate and lock off. On my training day I was shown to lock off the main switch in the board then perform the test sequences with the voltage indicators, put key in pocket after fitting warning notices etc etc. but today I spoke to someone who do their am2 a couple of years ago and said I should isolate and lock off the main isolator external to the board, and put the signs there. On the basis that if you only lock off at the board, then the very bottom of it still has live incomers in it. Where should I lock off?!? AM2 tomorrow any help is much appreciated. Cheers
