I just got a W/D combo unit that only needs a 120V outlet and my laundry room only has a 240V outlet. Rather than converting the 240V to a 120V, I want to be able to have both 120V and 220V outlets for flexibility and I noticed that my circuit breaker panel actually has a 20A circuit labeled "Washer" and a 30A labeled Dryer which controls the 240V outlet.
I also found a blank plate in the laundry room half way up a wall and I opened it and found wiring. I attached a picture of what I found and there are four pairs of wires in there.
It doesn't look like there is any ground wiring and so I will need to make sure the box is self-grounded, but if it is, does the condition of the wires cause anyone to think that installing an outlet there is more dangerous than normal (assuming I can find the wiring that comes from the 20 A "Washer" circuit)? Thanks in advance.

Here is a picture with the wiring moved out of the way a little bit. I am assuming now that the shiny metal wires in the back are the ground wires, is there any reason there are two and they are twisted together?! Also, not sure what the two white insulated wires are doing connected inside the box too, just wiring for down the line?
So I just tested the wiring with my non-contact voltage tester. After switching the circuit switches in the breaker box off then on, only one black ever came live, and it was the one twisted connected with the white. The bad news is that the circuit switch that turned it on was the 15A circuit for the downstairs bathroom fixtures and outlets. I guess I am going to need to just convert my 220V to a 120V as the most cost-effective solution. Thanks for everyone and their responses.
