Impact of AC Electric Current on Human Body
| Amount of current | Effect on body |
|---|---|
| 1 mA or less | No sensation is experienced with current less than 1 mA |
| More than 5 mA | Painful shock is experienced |
| 10 to 15 mA | Exposure to current may cause muscle contractions, which can cause some people to experience “freezing” of the electrical circuit. |
| 15 to 30 mA | Exposure to electrical current may cause muscle contractions, which can cause most people to experience “freezing” of the electrical circuit. |
| 30 to 50 mA | Breathing difficulties may occur, which could lead to unconsciousness, due to exposure to electrical current |
| 50 to 100 mA | Exposure to electrical current can potentially result in ventricular fibrillation of the heart. |
| 100 to 200 mA | Exposure to this level of electrical current has very high chance of ventricular fibrillation of the heart |
| More than 200 mA | Exposure to electrical current greater than 200 mA can result in severe burns and muscle contractions, which can lead to the heart stopping beating rather than fibrillation. |
| 1 Amperes and Higher | Exposure to this level of electrical current can cause permanent damage to body tissues |
