coax (grounding shield & AC?)

"Don't run it with AC with the grounded shield on it."

Hi, just wondering why it is not good to use the coax with grounded 
shield on for AC? I use coax for high voltage wire on my jacobs 
ladder. I did notice that if the grounding shield was left normal by 
the high voltage terminals of the NST it would pick up some of the 
electricity. A small, weak, arc on the other end of the shield would 
jump to anything conductive, such as your hand. Cutting the 
shield/coil of wire off about 1" from the terminals stopped the 
problem though. Is this the reason, or something else?
Thanks,
Matt G.

With DC it will handle approx 50 kV just as it is.



With 60 Hz AC strip the outer coax off and run a separate ground

cable, eg, 12 AWG. Don't run it with AC with the grounded shield on it.
