Is there an adapter for a NEMA 14-30 male plug to a NEMA 10-30 female receptacle?

Answer 1

No there is no adapter. Change your old dryer receptacle NEMA 10-30 to a new NEMA 14-30. This will allow you to plug the new dryer cord into the old wiring.

Range receptacle three to four

Look in the back of the dryer receptacle box that is in the wall. The three wires coming in should have a bare ground wire in the cable set. It wasn't brought to the receptacle because there was no place for it on the three wire receptacle. If you find it back there under a screw terminal just add another short piece of wire under the screw and then connect the other end of the short wire to the new ground terminal (G) on the new four position receptacle. The wire should be equal in size to the size of the wire that exists around the ground terminal now. If the house is so old that the dryer cable did not have a ground wire in it the code allows a separate green ground #10 wire to be taken from the breaker panel box to the existing range receptacle. This wire is to be bonded on each end. At the panel end to the ground buss and at the receptacle end around the ground screw at the back of the box unbroken and then to the new four position receptacle ground lug (G).

always use a test meter to ensure the circuit is, in fact, de energized.
