What gauge of wire is associated with the rating of 130?

The correct answer is associated with the wire gauge range of #6-2/0 and 3/0-397.5, which indicates that it can effectively handle the rating of 130 amps. In electrical applications, the diameter and material of the wire directly influence its current-carrying capacity, or ampacity.

The ampacity of a wire is determined by factors such as the gauge of the wire, insulation type, ambient temperature, and how many wires are bundled together. The gauge of wire has a standardized table that associates specific sizes with their maximum allowable current ratings. For instance, #6 gauge wire is capable of handling up to approximately 65 amps under normal conditions, while 2/0 gauge can handle up to about 150 amps, making their combined range suitable for a rating around 130 amps. This means when considering wire size, the larger the gauge number, the thinner the wire, and in contrast, a smaller gauge number represents a thicker wire that can handle more current.

When evaluating the other options, the ranges indicated for #4-2/0, #8-2/0, and #10-3/0 do not encompass the required ampacity for the rating of 130 amps, thus confirming
