a 12-15Kv 30mA unit would be a standard choice. ( if you
get shocked by
this transformer there is a chance you will live, anything
larger and
the chance drops to 0).

I strongly disagree. It's inaccurate to declare that any shock over 30mA gives zero chance of survival. Were that true, I probably would have died two or three times by now. I'm sure several of my fellow list members can recall painful, but nonlethal incidents in their professional and/or hobby endeavors.
I'm not a physician, but I do teach basic electronics using professionally prepared materials. According to USAF doctrine, the lethality of an electric shock is determined by numerous variables including the part of the body that receives the shock, the age and physical condition of the victim, the duration of the shock, the amount of current, and the promptness of emergency medical treatment.
Under tragically ideal conditions, 120vac might kill an unfortunate homeowner, while a power line worker who gets his hands blown off by contact with a 66kv line survives. I have survived very uncomfortable shocks from 115vac/400Hz aircraft current, as well as fierce "bites" from NSTs, while the national news outlets report several Taser (only 2-7mA) fatalities every year. Likewise, how often have we read about a lucky golfer who survives a lightning strike with nothing worse than a painful flash burn!
Except under carefully staged conditions, (like an electric chair!), a HV electric shock is a crapshoot, with the odds tipped strongly in favor of survival. I know many people who have been shocked, but I don't know anyone who has died of electrocution in my professional, social, or family circles.
I'm all for preaching safety, but the dangers shouldn't be overstated any more than they should be understated.
Cheers,
Greg
