Frequently Asked Questions (FAQs) About 5 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 5 AWG compare to 4 AWG?
5 AWG wire is smaller than 4 AWG, with a diameter of 4.621 mm compared to 5.189 mm for 4 AWG. It has a lower ampacity (e.g., 75 A at 90°C vs. 95 A for 4 AWG) and higher resistance.
What applications are suitable for 5 AWG wire?
5 AWG wire is typically used for medium-current applications, such as branch circuits, small appliances, or equipment wiring, with an ampacity of up to 75 A at 90°C.
What happens if the fusing current is exceeded?
If the fusing current is exceeded (e.g., 795 A for 10 seconds in 5 AWG), the wire will overheat and melt, potentially causing a fire hazard or circuit failure.
