If you mean 550 mega-amperes (as you wrote it, million amperes) it not only will kill a person, it will vaporize a person!

If you mean 550 milliamperes that depends on how it is applied to a person:

  • Currents of only 10 microamperes (millionths of an ampere) can kill if applied directly to the heart.
  • Currents of more than 30 milliamperes of AC (rms, 60 Hz) or 300 milliamps of DC can kill if applied to the skin.

Note: milliamperes is written mA, mega-amperes is written MA.
