AM2 assessment

[Mark.W]

Hi peeps,

I recently sat my AM2 and have been told that I did not meet the required standard on 2 sections.

Can someone please explain how to safely isolate the DOL starter. What I did was isolate and lock off the MCb, selected the voltage indicator checked it was working on a proving unit. I then tested L1-L2, L1-L3, L2-L3, L1-E, L2-E and L3-E. There was no N at the motor! I then rechecked the voltage indicator on the proving unit.

I also failed on the installation of lighting circuit, but I'm sure it was fine, it tested out fine and was fully operational at all 3 switches. I took my supply to the light fitting then the PL and SL to the first switch which was connected to the strappers. I linked the commons in the intermediate switch. Not sure what I could have got wrong!

The last thing I failed on was the installation of the swa to the 3ph socket? I terminated the gland either end ran a fly lead from the gland in the DB to MET, and a fly lead to the 3ph socket from the isolator via the earth screw on the isolator cover, all tests were good.

Please can someone she some light on what I could have done wrong?


Many thanks

Thank you Dan, do you have much more information on the heating system I should expect with any wiring diagrams that could help me with the system.

I haven't a clue what you're talking about matey I'm not an electrician. I just clocked that they were added by one of the lads and you'd asked about whatever it is and I remembered.

However hang in there, as some of the lads might be able to help you out.

I wouldn't worry too much about the s plan as you are given a complete schematic on how to connect it. What I would say is try and leave enough time to get it done.

Yeah I'm determined to get everything out of the way quickly as possible, as these heating systems always seem to give me the jitters. Overall I've never been one for anything involving exam conditions!
