| Jan 23, 2023 at 16:56 | comment | added | JACK | @fraxinus Right you are. I was addressing the "others are strictly 240v no questions asked." I answered this first and a lot has come out in the wash since then. i didn't come back and change anything because i was watching football. | |
| Jan 23, 2023 at 16:45 | comment | added | fraxinus | @JACK the OA does not need 240 to neutral, they need to power the particular appliance which is pretty much OK with 240V derived from the split phase setup. | |
| Jan 23, 2023 at 16:41 | comment | added | JACK | @user253751 Please read the answer again. You cannot take two residential 120V legs and connect them together to get 240V. You can connect a load between them and get 240V. The transformer is to step up the 120V to neutral circuit to a 240V to neutral (not phase to phase) cirvuit.. | |
| Jan 23, 2023 at 1:09 | comment | added | Wolf Mason | Yeah, going into this, I wasn't exactly clear as what kind of power requirements were needed, hence my reply above stating what is being used. I can repost it here though: The server that requires 240VAC is a Dell M1000e blade enclosure, the PSU's are Dell E3000E-S0 (Here is the link to the pictures of the PSU's: (drive.google.com/drive/folders/…) I understand that connecting 2 120 volt cables together do not equal 240v, it equals fireworks. Hence why I am asking the question. | |
| Jan 22, 2023 at 18:21 | comment | added | manassehkatz-Moving 2 Codidact | Actually OP really isn't clear about total power needed or neutral. Reality is that hardly anything that uses two wires (i.e. excluding 120 240 combos like us clothes dryers) cares whether second wire is hot or neutral. | |
| Jan 22, 2023 at 18:15 | comment | added | JACK | @manassehkatz-Moving2Codidact but the OP's looking for a single 240V line and a neutral for some of his servers. He's not using 240V servers to get more power, he's just trying to get them to work in the US. So for some of them, transformers would work. Our 120V /20 amp circuit would be equivalent to a 240V/10 amp circuit. | |

| Jan 22, 2023 at 17:40 | comment | added | JACK | @SimonB US houses have 240V phase to phase, not phase to neutral. | |
| Jan 22, 2023 at 17:20 | comment | added | Simon B | Why do you need a transformer when most US houses have a 240V supply already? | |
| Jan 22, 2023 at 15:21 | comment | added | manassehkatz-Moving 2 Codidact | Transformers would be a waste, even if 100% efficient. The reason to use 240V servers is to get more total power. A 240V 20A circuit would require a 120V 40A circuit (which would require expensive large wire) to run from a transformer. | |
