Hi yesterday I sat my FICA test and during the insulation resistance test I’m not sure if I made a mistake
I measured it doing individual circuits I had the main switch at db on but forgot to turn on the mcbs
I measured between Line at MCB and earth and Neutral bar to MCB then neutral bar to earth but not sure if this is giving incorrect readings as i never turned on the MCBs for the circuits?
