    AM2 exam is Monday Morning Need Help with PFC testing on 3 phase and rcbo testing on lightingcircuit

    This sould like the perfect response which Ive been looking for thanks! So let me get this right when doing the IR test on the sockets as it will be on a RCBO I am right in saying disconnect the load side from the fused spur and put the load side into the supply side of the spur. But put it...

    AM2 exam is Monday Morning Need Help with PFC testing on 3 phase and rcbo testing on lightingcircuit

    Thats great thank you! Can I ask what setting is it set on on the Megger MFT1770 tester I think its called. As in what would you set it to on the test meter to measure PFC. As my exam is monday I dont want to fail on this.

    AM2 exam is Monday Morning Need Help with PFC testing on 3 phase and rcbo testing on lightingcircuit

    So I would remove the conductors from the RCBO which I understand. But what I am asking is how would you test tripping times of the RCBO as it will be on the lighting circuit. But you cant expose any live parts of the lighting circuit etc. Then you cant expose any live parts on the board...

    AM2 exam is Monday Morning Need Help with PFC testing on 3 phase and rcbo testing on lightingcircuit

    Hi everyone, Not going to lie I am crapping my self for my AM2 exam on Monday Morning at 8:00. So I just need a few questions answered:- tell me if I am right or wrong. I will be using a megger tester by the way. PEFC testing 3 phase ( 3 probe test) :- Clamp croc clip on the neutral bar...

    How do you measure 3 Phase Supply confirming it is correct as in 400V between phases etc.

    So How would you test the lighting circuit RCBO? Like step by step?

    How do you measure 3 Phase Supply confirming it is correct as in 400V between phases etc.

    I understand that so what I said before is correct with two probe PSCC test Lines to Neutral PEFC test Lines to Earth. Also how would you complete RCD testing on a RCBO which is installed on a lighting circuit? I know how to do it for sockets. But not sure how to do it for lights as you cant...

    How do you measure 3 Phase Supply confirming it is correct as in 400V between phases etc.

    So when I do my am2 I will be aloud to simply use a two lead test on both? PEFC and PSCC there is only RCBO,s which I believe are on the lighting circuit and the ring main circuit. Obvs highest fig doubled and record on the test sheet as Ipf value.

    How do you measure 3 Phase Supply confirming it is correct as in 400V between phases etc.

    I know there is no place to record it but, the whole point of the two tests is to see under fault conditions if the protective devices installed can withstand the fault current (IpF) and can clear the fault current safely and not blow them to bits. So on my am2 exam I will simply use the megger...

    How do you measure 3 Phase Supply confirming it is correct as in 400V between phases etc.

    So testing wise I would do :- L1-N L2-N L3 -N L1-E L2 -E L3 -E I would expext to have 230volts? Again as you said tick in the confirm supply polarity. I also have another question carrying out Ipf test you ofcourse have PEFC ( 3 lead test) Simply test between Incoming L1- E L2-E L3- E...

    How do you measure 3 Phase Supply confirming it is correct as in 400V between phases etc.

    I have my AM2 exam and the question I have is how would you confirm supply polarity? Would you do the following tests:- L1-L2 L1-L3 L2-L3 L1-N L2 - N L3-N L1-E L2- E L3-E doing this you should expect 400V reading? Finally, test Neutral to Earth and expect to be 0 volts. Would the main...

    Just had Refresher Course for AM2 Exam is Monday need help with PSCC and PEFC!

    So another question how would you measure Zs at Main DB if you are not allowed to physically measure but, you have to calculate it using Zs=Ze+ (R1+R2) etc. But, where would you take your R1 and R2 reading etc? Just baffled.

    So I am writr in what I was saying earlier? That PSCC Simply test between L1- N L2- N L3-N double highest reading etc PEFC L1- E L2- E L3- E the highest value is noted. I then take the highest figure out of both tests and record this on my schedule of test results etc as Ipf? Also thanks...
