Im taking my AM2 on Monday and have a few questions just to get my testing on point. Firstly when testing continuity of cpc would a the assessor expect each cpc to be connected to the line conductor in a connector block for example (separately from the earth bar to eliminate parallel paths)? Or would a link from the earth bar to the load side of the circuit breaker for each circuit be acceptable?
Also when testing polarity do you think that the assessor would be happy for this to take place while testing Continuity of Cpc or would he/she expect it to be done after insulation resistance (as the sequence of tests is written)?
Also when testing PSCC on a 3phase install GN3 says if the meter being used can test between for example two phases (L1+L2) then the highest reading should be divided by 0.87 am i reading this correctly? As i have always only been told to double the highest reading when using a meter than cannot test between two phases.
With safe isolation (dont want to fall at the first hurdle) should the main distribution board be safely isolated and locked off before removing the cover? Because either way it will have to be reenergised (with the lid off) when testing PFC anyway or am i wrong?
Thanks
