Hi:

I obtained recently a NST rated 5000 V x 30 mA. It has two high-voltage
terminals with ceramic insulators, two input terminals for 115 V,
and no ground connection at the case or anywhere. It produces a
hot spark between wires attached to the terminals, with about 4 mm
of length, and can power a Jacob's ladder that extends the spark
to about 3 cm. Works best if I start with a distance where sparks
can't jump, and start a spark with an insulated screwdriver.

I imagine that without a ground connection I can operate it with
one of the output terminals grounded. Do someone have experience
with similar NSTs?
