What they don't tell you is that the bullet info is only good for rifles and pistols. Shotguns have their own system. (The number, or gauge of a shotgun is the number of lead balls the size of the barrel it takes to equal a pound. So a 12-gauge is larger than a 20-gauge.) And some rifles have odd sizes and numbers. (I know of an 8 mm magnum.)
This site has only basic info, if you want more, try their links or do an Internet search.

I find that very hard to believe. Welders (and fairly large high current ones) often use 1 gauge wire. Did you leave out a zero and mean 10 gauge wire? If not, what exactly are the lights you have and what exactly happened with this wire?
