When selecting an electrically conductive wire for an application, gauge is an important design consideration. However, the right gauge depends on a variety of factors.
For example, electrical circuits with higher amperage ratings require thicker wires to accommodate the load without experiencing excessive heat buildup. Using wires that are too thin for the specified circuit amperage can result in wire failure or ignition.
Avoiding these issues necessitates identifying the total amperage of a system—by calculating the effects of the planned load, the connected load, and the circuit length—and choosing a wire that is appropriate for it. The gauge of a wire imparts more than information about its thickness. Given its gauge, industry professionals can determine the following about a particular wire:.
As each wire gauge carries different physical and electrical properties, they are generally suitable for different purposes. Thinner gauges usually find application in more lightweight applications, while thicker gauges are employed for heavy-duty applications. Some common use cases for different wire gauges are outlined below: Gauge 4…………………………………………………………………. In an ounce of 24 gauge there is about 48 feet of wire. Half-hard is good in this size as it adds a little bit of body and strength to a very slender wire.
In an ounce of 26 gauge wire there is about 76 feet of wire. Mostly used for wire crocheting and wire knitting. Hard to handle, tendency to get tangled. Email address. Sign Up. Added to your cart:. Very thick wire. Create a personalised content profile. Measure ad performance.
