Are my assumptions correct?
'-' means touching.
#1
Mains L - Human body - GND/Earth = SHOCK
#2
Mains N - Human body - GND/Earth = "SAFE"
#3
Mains L/N - Transformer - Human body - GND/Earth = "SAFE"
#4
Mains L/N - Transformer - Human across transformer - GND/Earth = SHOCK
#5
Mains L/N - Transformer - Oscilloscope GND Probe = DAMAGE/SHOCK
#6
Mains L/N - Transformer - Oscilloscope (connected to mains via isolating transformer) GND Probe = "NO DAMAGE/SAFE"
#7
Mains L/N - Transformer - Mains Tester/Screwdriver = NO MAINS INDICATION/NEON OFF
