Frequently Asked Questions (FAQs) About 1 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.
What is ampacity?
Ampacity refers to the maximum amount of electric current a wire can carry safely without overheating, as defined by the National Electrical Code (NEC).
Why does ampacity vary with temperature?
Ampacity depends on the insulation's temperature rating (e.g., 60°C, 75°C, 90°C). Higher temperatures allow the wire to carry more current, but the insulation must withstand the heat.
What is fusing current?
Fusing current is the amount of current that will cause the wire to melt or "fuse" after a specific time (e.g., 10 seconds, 1 second, or 32 milliseconds).
Can I use 1 AWG wire for high-current applications?
Yes, 1 AWG wire is suitable for high-current applications, with an ampacity of up to 150 A at 90°C, depending on insulation and conditions.
