Frequently Asked Questions (FAQs) About 24 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 24 AWG compare to 23 AWG?
24 AWG wire is smaller than 23 AWG, with a diameter of 0.511 mm compared to 0.573 mm for 23 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 24 AWG wire?
24 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., 29 A for 10 seconds in 24 AWG), the wire will overheat and melt, potentially causing a fire hazard or circuit failure.
