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!
aha, now I feel smart!
