240v junction box However, you can make the junction box be dual-purpose. For instance, the best way to conceal such a junction box is to use a large, deep 4-11/16" square metal box (which you need for the cubic inches), then stick a 2-gang "mud ring" on it, then stick plain 120V receptacles or switches there, fed by totally separate 120V / #12 wires. $39.00

For instance, the best way to conceal such a junction box is to use a large, deep 4-11/16" square metal box (which you need for the cubic inches), then stick a 2-gang "mud ring" .Can I run the new line by attaching to the old one using the junction box. They just .My other thought is to just move the NEMA 10-30 outlet (or install a new NEMA 14 . However, you can make the junction box be dual-purpose.

Use appropriate sized wire-nuts and install a blank cover, put the new box where you want it , bring the wire in make sure to have at least 6” and the putter covering or insulation inside the box by 1/4” reconnect your receptacle and you are ready to plug in. Electric driers are usually #10 wire on a 30 amp breaker. Yes of course. All the usual rules for junctions and splices are in play. The box needs to be of an adequate size and type, the box must be readily accessible, the type of splice must be correct and of the correct sized wire and type, etc etc. But there is nothing in particular that is wrong with having a junction box for a 30A 240V circuit.
The NEC doesn't care what material, so long as it's a listed and approved junction box, of an appropriate size for the number and gauge of wires and other items that count towards "box fill" (internal clamps, devices in the junction box, etc.) I prefer steel for durability and better protection against faults, but that's an opinion, not code.
I'm in the process of moving 240V outlet. The outlet has three wires connected. See the image: In the junction box I can see the ground coming out of the outlet. See the image: So where is the ground wire inside the outlet? I'd like to know how this is handled. Update: for some reason I didn't notice ground attached to the neutral. But it is there any junction box with an all-metal-conduit path back to the service panel; any junction box with a #10 or larger ground wire back to the service panel, such as a water heater or air conditioner. any part of the Grounding Electrode System, those copper wires that come out of the panel to go to water pipes or ground rods. There needs to be a junction box in the wall or mounted to the wall. I recommend a 4-11/16" steel square box because it has lots of room for future expansion, but a 4" square by 2-1/8" deep box will also suffice. This is high current stuff that will arc spectaularly, so it's no time to be fooling with plastic boxes. the box screw ear, and receptacle, have hard flush clean metal contact, with the screws bottomed out (not floating on drywall ears; no little plastic squares on the screws). Or the receptacle is labeled "self-grounding" meaning it has a feature to assure good contact with the mounting screw.
As far as selecting an actual box, from experience, I recommend getting a 2-gang plastic box (or something equivalent in size if you want to use metal). The larger the capacity the better because a NEMA 14-30 receptacle with four #10 wires is not only bulky, but can be a very stiff pain to manipulate. Yes, 120V and 240V can cohabitate. Both of those are classified as Class 1 circuits. The highest voltage present in the box will be 240V, and with any normal wiring (NM, THHN in conduit, MC, etc.) all the wiring will have insulation rated well above that voltage. However, depending on the plug on your charger, it may not fit in half a 2-gang. However, you can make the junction box be dual-purpose.
