Re: Neon Sign Transformer

The beehive is called a high voltage bushing.   The two 1/4 inch studs near
each other are the 120 VAC inputs.  The 1/4 inch stud on the other end of
the case is your ground which must be connected to the green power line
ground.  Test with a small climbing arc fashioned from two old cut up
clothes hangers.  Set base at 1/4 inch spacing and top at 4 inch spacing ---
10 inches tall overall.  Be careful --- this thing can kill you if you touch
