How are Wires Sized?
Wire gauge is what measures the size of a wire through its diameter or cross sectional area. How much gauge a wire has will lead to how much current will be able to flow within the wire. This measurement will also govern the resistance of the wire and also the weight per unit of length.
What Electrical Wires are Installed in Homes?
