Does anyone know a good site for explaining different kinds of electrical wire? Or want to create a "Tutorial for electrical Dummies"? All my questions would take too much space. But. . . I went to Lowes and they have a chart almost from floor to ceiling. Some individual wire, have positive, negative, ground wires inside the casing. Some have a large mass of copper wires to make one really thick wire. I have seen suggestions of two gauge, four gauge, etc. Thick as my thumb! How to attach connectors? What to use for charging house battery bank with alternator, generator, solar?<br>Any suggestions will be greatly appreciated. <br>
