While setting up a computer power supply, I'm worried about plugging it into a wall outlet. If something goes wrong and I receive a shock, could the household voltage seriously injure or kill me? Is simply connecting the power supply normally considered dangerous?
1 Answer
The outcome depends on several factors, including the voltage, current path, contact time, skin condition, and whether the shock crosses the heart. A brief household shock may cause only pain or burns, but there’s no safe way to test it and no reliable guarantee that it will be harmless. If someone is shocked and has chest pain, trouble breathing, fainting, burns, confusion, or a persistent abnormal heartbeat, seek emergency medical help immediately.
