Frequently Asked Questions (FAQs) About 2 AWG Wire
What does AWG stand for?
AWG stands for American Wire Gauge, a standardized system for measuring wire sizes. The smaller the AWG number, the larger the wire diameter.
How does 2 AWG compare to 1 AWG?
2 AWG wire is slightly smaller than 1 AWG, with a diameter of 6.544 mm compared to 7.348 mm for 1 AWG. It has a lower ampacity (e.g., 130 A at 90°C vs. 150 A for 1 AWG) and higher resistance.
What is the significance of fusing current?
Fusing current indicates the current at which the wire will melt after a specific duration (e.g., 10 seconds, 1 second, or 32 milliseconds). For 2 AWG, this is 1300 A for 10 seconds.
Can 2 AWG wire be used for residential wiring?
Yes, 2 AWG wire can be used for high-current residential applications, such as subpanels or large appliances, with an ampacity of up to 130 A at 90°C, depending on insulation and local codes.
