I have stripped one wire, the black/hot/positive one, for a 120v appliance. I had to cut away the outer plastic that surrouneds all three wires, and now I'm afraid I may have nicked a small hole into one or more of the wires, and am deathly afraid of getting shocked.
Is there a way to test for very small holes in wires? The ole put-water-on-something-inflatable-and-listen/feel-for-bubbles comes to mind, but this is electronics. I suppose I could closely inspect the wires, but am hoping there's a better way.
