@Ed Evans ,

Test centres are not obliged to provide a choice of manufacturers when it comes to test equipment. They are only obliged to provide a certain number of devices for a given number of bays. I had no choice... if I had a choice between say Megger and Kewtech or Fluke and Kewtech... I would have opted to use the Megger or Fluke.

The AM2 test centre specification only states the equipment they must provide... it does not stipulate candidates must have a choice.

I was also curious about what MFT they would provide it is definitely reassuring knowing you get a selection rather than turning up and "here is your tester" only to be something totally alien to you.

Ed Evans - would you first tackle the faults making sure you have continuity from DB to the said area on all conductors/cpc & then if yes move on to using other testing methods if you cannot find the fault e.g I.R testing etc

Don't expect a choice of test equipment. See my post above and read the test centre specification document. It tells you what centres are obliged to provide. Don't expect it to be the best quality either, the tool kits get alot of abuse.

As for the fault finding... I would go straight for a test that is the most appropriate for the fault. You can assume everything else is perfect apart from the fault you are trying to find.

Ah I see, sorry I misread, thanks for the information sparky its always nice to learn as much info as possible.
I guess when the time comes I would enquire about what mft they use not keen on the kewtech like yourself
I definitely need to get some practice in the fault finding department before even booking the am2.

Hi mate,
The training center provides you will all the tools and test equipment you need. From what I can remember when I did mine there was a selection of testers and I was asked to preform safe isolation and had to select the tester and a proving unit.
Usually the examiner will put faults on the test rig and you have to find them.
when you do your installation he dismantles. Your accessories/ wiring and checks your connections to see if there’s any conductor showing.
but if your the type of guy asking questions on this forum before you do it you’ll be fine.
good luck

you are given normally a fluke, megger and possibly a metrel multifunction tester. Do NOT use these for safe isolation.

Do not start with the same continuity tests as if it possibly is taking out the cb then continuity would show as ok, wouldn't it?

read the descriptor, step, back and think what the cause could be. You will have plenty of time doing this as you will not be wasting time looking for a test result that would not prove anything.

for example: the cat 5 (bt) fault one of them is 2 lines crossed over. S, continuity red to red ok
blue to blue open. But that is not the fault because if the blue at one end went to the green it would show open because the blue is going to the green. but it is not open it is crossed.

you are given at least 3 major brand multifunction testers.
all the AM2 installations are identical.
the fault finding is done as follows:

1 the assessor is told what fault to switch on, you cannot see the switch.
2. you are given a description of a fault ie: the breaker trips when the central heating is called for. This gives you the area to look in ie the solar thermal system.
you will be given a total of 7 faults in total which you are supposed to find in the order you are given. Your answer should identify the fault, where it is and what you would do to rectify it. the assessor does not pick the faults as he is given them by NET.
the fault finding is done after you have carried out safe isolation as it is done dead. good luck
Thank you for this really helpful

Thanks mate
Also when i go through all the different tests in the inspection and testing section I will connect the cpc and neutral leads together because it is a 3 phase board and i will be doing 3 phase tests for example ze and pfc tests , is that correct?
thanks
