These connections were behind the flush mounted dryer receptacle. They fed 2 240 volt AC receptacles run on the surface in NM-B cables. This is 12-2 NM-B.
This is the receptacle end of the AC outlet fed from the dryer circuit.
This was fed by a 20 amp 12-3 NM-B. The splice was buried without a box behind the sheetrock. It fed 2 duplex receptacles wired with 14-2, one on each circuit.
