A 200 amp circuit that is 25 feet long should use wire of which AWG rating?

Question

Quizplus · Accepted Answer

For a 200 amp circuit, especially one that is relatively short at 25 feet, a 2 gauge (ga.) wire is appropriate. This is because larger amperage circuits require thicker wires to safely conduct the electricity without overheating. The American Wire Gauge (AWG) system shows that lower numbers indicate thicker wires. Thus, for a high capacity circuit like 200 amps, a 2 gauge wire is suitable, whereas options A, B, and D represent wires that are too thin to safely handle such a load.
