henley block / fuse seal
It should detect higher impedance leakage than necessary to light even a
neon (since the volt stick measures almost pure electric field, through
air + its plastic cap + whatever insulation is on the cable etc).
However there may well be situations where there's a live conductor
whose field is shielded by a grounded conductor:
If you were to read the instructions it says that.
