I posted on here the other day about some suspicious 240v cable and followed the recommendations to replace it. I was already leaning that way but was kind of hoping to be told I was overthinking it. But you all confirmed what I thought. I ran close to 25’ of 10/2 cable from the second story to the basement. Nothing is wired yet because it is late and I don’t want to turn on the main breaker.

My step dad let me borrow a 50’ fishing tape and 10’ endoscope which were really helpful. I did not have to cut any walls!

    Since you went with 10/2 for a 240v outlet that means your cable will have two hots and a single ground. But the cable you bought will have a black, white and bare/green wire. Make sure that you wrap both ends of the white conductor with red electrical tape to indicate that it is also a hot wire. White normally indicates a neutral, but since you won’t have a neutral wire in this cable, it’s important to mark it. Otherwise someone else may work on this outlet in the future, see a white wire, assume it’s a neutral, wire something up with it as a neutral, and give themselves a pretty bad shock.

      Yup, I already have the electrical tape to mark it. Though I was told I could mark it red or black and both are universal markings for hot wire. Is that wrong? It doesn’t matter here because I have red tape but for future reference it would be good to know

        You can mark it either red or black, but you already have one black wire, so it would be best to mark it red, just to differentiate it.

    I’m an electrician. It is too late but for future reference all new work must be done up to code. An electric dryer requires 10/3 on a 30A breaker that is listed for the panel.

    While this is not code compliant, 10/2 will still work but requires you to install the jumper from the neutral to the ground inside the dryer itself.

      Ya, I know I need to jump the ground when wiring to power cable for the dryer. I was going to do 10/3 since I had the money for it, but lowes and Home Depot were both sold out when I went to pick it up. Whirlpool told me 10/2 would work so I just went with that in the effort of saving time. New dryer is delivered Tuesday so I want the wiring done before then. The 30a double pole breaker was easy though. Probably the least questionable part of this process
