| Jun 7, 2022 at 17:21 | comment | added | P2000 | @user253751 that would be a great question to ask here, or better, on the DIY site. | |
| Jun 7, 2022 at 10:11 | comment | added | Criticizing Israel not allowed | yes... your answer says why there shouldn't be one, but I'm not satisfied with the explanation. | |
| Jun 6, 2022 at 1:58 | comment | added | P2000 | @user253751 boot-leg grounds are illegal for various reasons. There should be no deliberate chassis to neutral connection. The chassis should be grounded or left fully insulated. A neutral interrupt then does not result in a hazardous chassis. So back to your original comment "then it becomes live": a faulty neutral would have to coincide with a short to chassis. That also makes two problems. | |
| Jun 5, 2022 at 19:36 | comment | added | Criticizing Israel not allowed | Your answer suggests the normal condition is hazardous. As far as I'm aware a properly functioning neutral line shouldn't have a high enough voltage to cause any hazard. The hazard occurs when it is not properly functioning. | |
| Jun 3, 2022 at 17:23 | comment | added | P2000 | @user253751 chassis should never deliberately be connected to neutral for the reason mentioned in my answer, whether there is ground available or not. If we remove the deliberate connection scenario, what other scenario would you consider? | |
| Jun 3, 2022 at 15:06 | comment | added | Criticizing Israel not allowed | Imagine that a metal equipment chassis is connected to neutral, deliberately. Also imagine the neutral wire is accidentally not connected. The chassis is live and touching it will shock you. | |
| Jun 3, 2022 at 15:01 | comment | added | P2000 | @user253751 neutral disconnects are indeed generally a problem, but I am not following your specific case here: where is your wire disconnected and where are you touching it? | |
| Jun 3, 2022 at 9:05 | comment | added | Criticizing Israel not allowed | Also, the neutral can get disconnected because of some problem, and then it becomes live and shocks you. If neutral and ground are separate wires, then you only get shocked if two problems happen at the same time. | |
