What is the point of buying grounding wire?
Many stores seem to sell "grounding wire". This is a solid copper wire, similar to normal THHN wires used to do house wiring, except without the plastic jacket. I'm confused why you would bother buying grounding wire. Can't you just strip your normal wire as needed and get the same thing? Grounding wire seems cheaper than jacketed wire, but only by a little. These savings are offset by the fact that you would have to invest in a separate spool of grounding wire, and they are not realized until you've actually used up a large amount of grounding and jacketed wire. I imagine for a contractor who lays down miles of wire, this is significant, but for a casual DIYer the price difference seems moot. I suppose it is convenient that you don't have to strip it. But this is offset by needing to store yet another spool of wire. Also, stripping wire isn't hard. Is there some fundamental way in which "grounding wire" is better for grounding than stripped solid THHN wire? Or is it just a matter of cost + convenience?
