Frequently Asked Questions (FAQs) About 33 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 33 AWG compare to 32 AWG?

33 AWG wire is smaller than 32 AWG, with a diameter of 0.18 mm compared to 0.202 mm for 32 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 33 AWG wire?

33 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., 6 A for 10 seconds in 33 AWG), the wire will overheat and melt, potentially causing a fire hazard or circuit failure.
