Understanding AWG (American Wire Gauge)
AWG, or American Wire Gauge, is a standardized wire gauge system used to specify the diameter of electrical wires. The smaller the gauge number, the larger the wire diameter. For instance, 1 AWG wire has a diameter of 0.2893 inches (7.348 mm). Understanding AWG is essential for selecting the right wire for your electrical projects.
Why Choose Copper Wire?
Copper is a popular choice for electrical wiring due to its excellent conductivity, ductility, and resistance to corrosion. It offers lower resistance compared to aluminum, making it more efficient for transmitting electricity over long distances. Additionally, copper wire is more durable and can withstand harsher environmental conditions.
