Am new member so sorry if i'm going over similar threads.
Am taking the 2391 practical soon and would like as much info. as poss. on what to expect.
Am i right in saying you have to do a P.I.R. test ( not inspection ) on a 3 phase board feeding a number of ccts which include a 230v. board which also feeds a number of ccts ??
If so do you carry out all tests on the 3phase board and note results and then carry out tests on the 230v. board and note results. ??
Any info. will be appreciated which will help on this infamously nerve racking exam !!!
