As he measured 0V between mains earth and the earth rod, the issue was not caused by any problems in mains wiring. I suggest also measuring resistance, just to be sure. |

Or just the caps? --- End quote --- This is an OK leakage current thru Y caps (on a high side though). If PSU has no earth connection as many laptop power bricks, it acts as intended. Desktop PCs are always grounded. Double insulated devices which do not have an earth connection normally should have lower leakage current, like < 0.4mA. |

If anyone, including you, has doubts as to the safety of an electrical installation anywhere, call someone qualified, not a random person on a forum. It does appear that the equipment in the first portion of the video is connected via an ungrounded socket (not that such a thing has any business being used), which would indeed explain matters. Whether that is safe or not depends on further details we are lacking. |

Looks like some extremely outdated garbage even with no recess for a plug, not to say earth connection. I don't think anything like this can be possibly legal these days. Electrician most likely won't be able to do anything with this as cable in the wall most likely does not contain an earth conductor. And therefore cannot be fixed without doing total rewiring. |

Thanks you for your answers. Do you rekkon something is wrong with the pc supply? I know i need to have an electrician look at it. In fact it's not even that Long ago i had an electrician say that everything was fine. i just couldnt help but doubt him because og All the shocks that i got. (You where right about the video. Im just a 13yo kid/ee hobbyist that thought something was wrong. It's the first time im working with house wiring. As a 100% self taught engineer i just thought that it couldt be good to get shocked constantly. Sorry for dumb questions and Spelling mistakes as i said im 13, still lerning and it's the first time im doing this kinda stuff. But one time gotta be the first one and i have learned a Lot!! Thanks for that.) "The Expert in anything was once a Beginner" -Helen Hayes |
