What is the correct order of amperages associated with copper wires sized 8, 10, 12, and 14 from highest to lowest?

30, 15, 40, 20
40, 30, 20, 15
15, 20, 30, 40
20, 15, 40, 30

The correct answer is: 40, 30, 20, 15

The correct order of amperages associated with copper wires sized 8, 10, 12, and 14 from highest to lowest is based on the National Electrical Code (NEC) guidelines, which specify the maximum allowable amperage for different wire sizes. For copper wires, the typical ampacity is as follows: - 8-gauge wire can safely carry 40 amps. - 10-gauge wire can carry 30 amps. - 12-gauge wire is rated for 20 amps. - 14-gauge wire is rated for 15 amps. When arranged from highest to lowest, the correct order is 40, 30, 20, and 15, which corresponds to the 8, 10, 12, and 14-gauge wires respectively. Therefore, the answer accurately lists the amperages in descending order, illustrating the principle that larger gauge wires can carry more current than smaller gauge wires, complying with NEC standards. This understanding is crucial for ensuring electrical safety and compliance in residential and commercial settings.
