Hi everyone,

My resit on my AM2 live testing is monday coming and I need some help/ gudiance on anyone who has sat theres to help me.

Confim polarity by measuring the voltage between each phase to N and each phase to earth, then phase to phase to ensure I am getting 230/400V etc.

So then, Ze test disconnect main earth and test each phase ( 3phases) to earth . Highest value record on test sheet as Ze. Then reinstate the main earth. Make sure test equipment is set to 2 test lead LOW or NO TRIP.

Zs test at db, same as ze but, the main earth is connected. Again test each phase to earth. Record highest value on the test sheet. Again, test meter on 2 test lead Low or No trip.

Then, PFC testing, set the test equipment to 2 test lead high I think it is... then measure PEFC so each phase to earth so L1- E, L2- E and L3-E. Mental note of this value.

Then same test again but PSCC so measuring each phase to neutral. So, L1-N , L2- N, L3-N. Mental note of this value.

The test equipment I am using cant measure phase to phase so. Simply take highest value and double it normally PSCC value.

Record this on test sheet as IpF.

Then cover back on db. Then the board can be fully energised/ lock off taken off. Then carry out RCD tripping times on the ring at the FURTHEST point. Record tripping times on test sheet and functional testing of the test button. Then, functional testing of all other circuits to confirm that they are working as they should be etc.

Then phase rotation ensure I am getting correct phases at the commando outlet point and the motor circuit.

Does that all sound right? If not let me know please as my resit is Monday morning!

Cheers!
 
Ryan,
Which Megger MFT are you using? as you should be able to download from Megger user instructions so you can be sure what the tester can do.Did you attend a course prior to being booked for the test?

I think of the top of my head its a Megger MFT1730 or 1740. Ive been explain how to use it but, kind of forgot what them settings where as in the workplace I use a different tester with different settings alltogether.

I quite understand that as it takes a bit of time of getting used to a tester what it can do. My fundamental question to you is that have you undertook a learning course prior to this test?

I done a refreshers course just before my am2 exam but, they just told us to watch videos on the tester. Which I did do before the exam and in the exam I had to ask again for clarifcation on how the megger tester works etc.
 
I wish you all the best of luck with the retest but I am very concerned regarding the questions that you are asking at this stage and the impression of the teaching given to you unless you have just paid to do the test on the day.
 

Any trainee or apprentice won't go far wrong watching some of this lads vids.

Subscribe to this guy ....:thumbsup:

Worthy of a thread of good practice makes a change to all the rubbish on YouTube.

Cheers
