Frequently Asked Questions (FAQs) About 29 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 29 AWG compare to 28 AWG?
29 AWG wire is smaller than 28 AWG, with a diameter of 0.286 mm compared to 0.321 mm for 28 AWG. It has the same ampacity (0 A at 90°C) but a smaller cross-sectional area and higher resistance.
What applications are suitable for 29 AWG wire?
29 AWG wire is typically used for extremely low-current applications, such as fine electronics, hobby projects, or small signal wiring, due to its limited ampacity.
What happens if the fusing current is exceeded?
If the fusing current is exceeded (e.g., 12 A for 10 seconds in 29 AWG), the wire will overheat and melt, potentially causing a fire hazard or circuit failure.
