The subtle relationship between AWG and B&S: Why can't we confuse them?
The American Wire Gauge (AWG) has been used in North America since 1857, primarily to measure the diameter of non-ferrous electrical conductors. The function of AWG is to help determine the current carrying capacity of a wire, but the distinction between it and the B&S (Brown and Sharp) specification is often overlooked. What is the subtle connection between AWG and B&S, and why shouldn't we confuse them? This article will reveal the relationship between the two.
Origin of AWG
The origins of AWG can be traced back to the number of wire drawing operations during the manufacturing process of electrical wires. The more times each diameter of wire needs to be drawn, the thinner the wire diameter. Standardization on the AWG system helps to increase efficiency when selecting wire for a specific application.
Differences between B&S and AWG
Although the AWG specification and the B&S sheet metal specification appear similar, they serve very different applications. AWG is designed for round solid electrical wire, while B&S is mainly used for metal sheets.
Using B&S to describe wires is technically incorrect rather than using AWG.
AWG Specifications
Each range of AWG represents a specified wire diameter, and as the number goes up, the wire diameter decreases logarithmically. The AWG table is designed for single solid conductors, but for stranded wires, calculations are based on the cross-sectional area of the equivalent solid conductor. This means that stranded wire will have a slightly larger overall diameter than solid wire of the same AWG.
Calculation Method of AWG
The AWG calculation involves the diameter and cross-sectional area of the wire. The different AWG skills allow engineers and technicians to quickly calculate the required specifications and corresponding performance.
The importance of AWG in practical applications
In practical applications, such as electrical engineering, the selection of cables is crucial to ensure safety and efficiency.
Whether it is a residential or commercial electrical installation, making the correct choice of the appropriate wire gauge is extremely important.
Confusion between the public and the professional world
For many non-professionals, mixing AWG and B&S can lead to confusion in understanding, which may affect overall safety and performance. Understanding the difference between the two can help users choose appropriate wires to avoid unnecessary losses.
SummaryThere is a subtle relationship between AWG and B&S, and confusing them may have a negative impact on electrical safety. Proper understanding of these standards not only enables professionals to make informed choices, but also educates the public to avoid potential dangers caused by misunderstandings. In an age of increasing reliance on electrical technology, have you ever wondered what impact correctness has on safety when using these standards?
