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
