OP
wozz
Forget the phase to phase test , they encourage them to even calculate zs, s it is a live test and is not needed.
I had a lad for 2 weeks work experience and he nearly fainted when i performed one in front of him!.
He had been told on his 5 week course that it was not the done thing now!! Beggars belief.
the only organisation ive heard promoting calc Zs is the NIC.
Im all for reducing risk ect, but i would like to see the wording for my own interpretation.
