Kcmil meaning

A circular mil is a unit of area, equal to the area of a circle with a diameter of one mil one thousandth of an inch or 0, kcmil meaning. It corresponds to approximately 5, kcmil meaning. It is a unit intended for referring to the area kcmil meaning a wire with a circular cross section. KCMIL stands for thousand circular mils, which is a unit of measurement used in the electrical and wire industry.

Some countries have different ways of measuring electrical wire size, making it tough to standardize one set of measurements. In other countries overseas, like Britain, you might see the now withdrawn Standard Wire Gauge SWG or the more widely used IEC , the dominant gauge sizing system found in most of the world. A wire is sized by cutting a cross-section of AWG-sized wire and measuring its diameter. When a wire is larger than , it has to be measured in MCM thousands of circular mils , or kcmil. Understanding how AWG sizing works goes a long way toward helping answer other common electrical questions, including how much current it can safely handle. Wire gauges also relate to carrying capacity, telling us how much current a copper conductor can safely carry without damaging itself or its insulation. When electricity is carried by a conductor, it generates heat as a by-product.

Kcmil meaning

A circular mil is a unit of area , equal to the area of a circle with a diameter of one mil one thousandth of an inch or 0. It corresponds to approximately 5. It is a unit intended for referring to the area of a wire with a circular cross section. The area in circular mils, A , of a circle with a diameter of d mils, is given by the formula:. In many NEC publications and uses, large wires may be expressed in thousands of circular mils, which is abbreviated in two different ways: kcmil [1] or MCM. As a unit of area, the circular mil can be converted to other units such as square inches or square millimetres. The formula for the area of an arbitrary circle in circular mils can be derived by applying this conversion factor to the standard formula for the area of a circle which gives its result in square mils. To equate circular mils with square inches rather than square mils, the definition of a mil in inches can be substituted:. Likewise, since 1 inch is defined as exactly A AWG solid wire is defined to have a diameter of exactly 0. The cross-sectional area of this wire is:. Some tables give conversions to circular millimetres cmm. However, this unit is rarely used in practice.

Kcmil meaning

Both kcmil and AWG denote the cross-section of wires electrical conductors, to be exact. Here is what each of these wire size units means:. Well, first of all, we have to understand that all kcmil wires are bigger have a larger diameter than AWG wires. Here is an example that demonstrates that and the labels we are going to use to convert kcmil to AWG. To help everybody out, we have created simple kcmil to AWG calculator 1st calculator that converts automatically and AWG to kcmil calculator 2nd calculator that does the reverse.

This way, there is less risk of the conductor overheating, allowing it to safely carry current and maintain its durability for longer. Browse Definitions. A AWG solid wire is defined to have a diameter of exactly 0. Term » Definition. Oliver British. Can Silicone Damage Automotive Paint? How do you prevent heat issues from impacting conductors? Priya Indian. Category : Units of area. Likewise, since 1 inch is defined as exactly Veena Indian. Is There a Copper Shortage Looming? New Life for Old Mines? Unlike clothing sizes which can vary wildly from retailer to retailer, AWG sizing is standardized across all wire manufacturers in the U. Rest assured that the wire you buy from one company will be the same size as copper wire bought from another manufacturer.

We generally use these thick wires when we need more than amp service. Which kcmil wire exactly we need for carrying high currents is determined by the kcmil wire size chart check the chart further on. Example: What is the ampacity of kcmil copper wire?
