Stranded Aluminum Wire Sizes

Aluminum wires come in different types.

Stranded aluminum wire sizes. Wire gauge refers the physical size of the wire rated with a numerical designation that runs opposite to the diameter of the conductors in other words the smaller the wire gauge number the larger the wire diameter. Covered aerial mv. Wire gauge calculations wire diameter calculations. Types thwn and rhw are the most commonly used ones.
