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. The key is to position junction boxes in locations that are a) properly mounted, b) allow at least 7" of wire ends to enter the box; and c) allow routing of the dryer and supply in a neat and workmanlike manner compatible with any . The only way to extend the circuit is to retrofit ground to the original location, see NEC 250.130(C). This is a 10 AWG wire to any junction box containing a #10 or larger wire which is going back to the same panel. It can also go to the bare wire from the panel to your ground rods. Never cut that wire, use a split-bolt to attach to it.

The EE says that you cannot splice circuits in a junction box - the case in point being a branch circuit running from a breaker in a panel to a junction box and then spliced to conductors running to two separate loads (in this case lights on opposite sides of a room). All splices need to be made in permanently accessible junction boxes. Wire nuts can be used for copper to copper splices. Aluminum to copper will require special connectors like a Polaris. Older 3 wire circuits should not be extended for 120/240 units that require 4 wires.The proper approach is to add a junction box at each splice - we never splice 120/240V wires without including them in a box. You can reduce the wiring work a little by using plastic boxes instead of steel - avoiding having to also connect the box to the ground wire. On construction sites, a box shall not be required for splices or junction connections where the circuit conductors are multiconductor cord or cable assemblies, provided that the equipment grounding continuity is maintained with or without the box.

Splices in electrical wire that carries electrical current in a building (such as for lights or electrical outlets) must be completed using an approved mechanical connector and must be enclosed in an approved junction box which itself is secured to the structure. 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. STEP 1 : Prepare and install the junction box. Use the electrician’s or linesman’s pliers to remove two of the knockouts on the new junction box, which will house and protect the spliced wires.
