This video will show you how dangerous Electricity is... - http://www.brainfiller.com/ArcFlashwhilerackingabreaker.wmv This post has been edited by woodyblade: Feb 25 2009, 11:34 AM -------------------- Murphy's Law: If Anything Can Go Wrong, It Will, Often At The Worst Possible Time.

Current kills not voltage, I think the accepted industry standard states anything up to 50vac is safe. Anyway I stand by what I've previously stated. Just surprised to see such a video in the 'fun' section of a site who's primary purpose is related to malfunctioning computers.
Perhaps given the standard this video implies I could unearth some footage of burnt and charred bodies to "show fire is dangerous." |

It's neither Amperage or Voltage that kills, its the combination of the two (Resistance is a given as it is produced by your body but will very person to person and moment to moment). 12V at 2000 Amps will kill and 220V at 5A will kill.
However the video is a good warning since when working on the PSU of a PC you are dealing with a "Step-Down Converter" (The PSU drops line voltage from 110-120v to 12-1.5v depending on usage, and converts AC to DC) which is very similar to a transformer (If you've ever seen one of those go off like a 36 inch diameter bottle rocket, you know the kind of power they pack). --------------------  You can't bash an eMachine until you've owned one, then you just use a baseball bat. |

QUOTE(clubhouse @ May 10 2009, 02:02 AM)  Perhaps given the standard this video implies I could unearth some footage of burnt and charred bodies to "show fire is dangerous." My Dad is an electrician been working on the Railway Electrics for nearly 30 years, He sent me a Presentation about burns from Electric which he got from some friends where he works, that isn't suitable for here the images are a bit graphic (Bit of a Sherlock statement  ) but I know how dangerous fire can be and what burns are like.Although I never thought a PSU in a computer is similar, Never built a comp myself so don't know really know anything about the PSU, although I will eventually build a comp in the future, guess it's something else to consider. -------------------- Murphy's Law: If Anything Can Go Wrong, It Will, Often At The Worst Possible Time.
