The American Wire Gauge chart is based on the number of dies originally required to draw the copper down to the required dimensional size.

For the 00, , etc. Similar to dB in signal and power levels. This estimate is based on nick-free soft annealed Cu wire having a tensile strength of pounds per square inch. Select Copper or Aluminum Copper Aluminum. Enter 1-way circuit length in feet the calculation is for the round trip distance. This chart of American Wire Gauge AWG wire sizes and rated ampacities is data intended for the pleasure of our readers only. Typographical errors, etc.

If you work in a sector involving the measurement of cables or wires, you may have come across the terms AWG and mm 2. Both units of measurement are used to indicate the thickness or diameter of cables and wires, but they are not interchangeable. To convert between these two units, you will need a conversion table. The higher the AWG number, the thinner the cable. On the other hand, mm 2 stands for square millimeters and is used as a standard unit of measurement for the diameter of cables and wires in most parts of the world that use the metric decimal system. A thin cable has higher resistance to the flow of current due to its smaller cross-sectional area. Conversely, a thicker cable has lower resistance and can efficiently carry higher currents. These tables usually list AWG sizes in one column and their corresponding mm 2 measurements in another column. You can use these tables to find the equivalent between the two units for any given size. Download the conversion table in PDF format here. When looking for the maximum permissible currents for each cable according to AWG, it is important to highlight that the UNE-HD standard specifies the formula for calculating permissible currents.

Installation of electrical wire can be hazardous and, if done improperly can result in personal injury or property damage. Ampacities are based on the NEC and do not reflect any temperature correction or ampacity adjustments that may be required. Please consult a qualified electrician or professional engineer to determine the appropriate values for your specific application. Home News Careers. Ampacity Charts Wire Gauge Chart. Find Retailers.

This converter has two text fields and control buttons that are used to execute different actions during the calculations. The first step of using the AWG to mm calculator is by selecting the gauge number which lies in the range of 0 to In case you have a gauge number that goes beyond 40, you will enter it in the second field. Enter gauge. It executes the conversions within a single click displaying the result in millimeters mm. You will also get the cross sectional area in square millimeters which is calculated automatically with the diameter in millimeters. The diameter of the gauge number 36 is 0. For example; If the American wire gauge is 56 AWG , find the diameter in millimeters and the Cross sectional area in square millimeters. The gauge number is more than 40 and hence you will enter the value in the blank text field.

Picking exactly the right wire size is not an easy task at all. Different AWG American Wire Gauge wires have different diameters, cross-sections, and allow only a limited number of amps to flow through them. To adequately figure out what size AWG wire you need, you require at least a wire gauge chart. AWG is a logarithmic stepped standardized wire gauge system used since Example of a good simplification: The higher the AWG gauge wire numbers like 14, 16, 20, 40 , the thinner the wire. This overview article about AWG gauge wires will give you all the info you need about wire sizing. In the 1st Chapter , we focus on the wire gauge chart, denoting diameter mm , cross-section mm2 , and amperage maximum allowed amps for each AWG wire.

Calculating Ampacity Needs: To calculate the load requirement for a circuit, first add up the wattages of all devices planned for the circuit. The distance your wire needs to go can impact the gauge size you need. What are the benefits of using copper vs aluminium conductors? As you might guess, the rated ampacities are just a rule of thumb. Essentially, a thicker wire will have less resistance and carry more voltage at a longer distance. These metals are both ductile and Gauge load amp wire chart. If you work in a sector involving the measurement of cables or wires, you may have come across the terms AWG and mm 2. The following chart is a guideline of ampacity or copper wire current carrying capacity following the Handbook of Electronic Tables and Formulas for American Wire Gauge. Google Author Verification.

In reality there is no exact correspondence between these two types of measurement since the specifications of both systems differ in terms of specification and resistance, however with the following application you can have a very good reference. It is an American standard for the size of conductors and cables. The AWG standard includes copper, aluminum, and other wire materials.

Enter 1-way circuit length in feet the calculation is for the round trip distance. Current is measured in amperes amps. Aceptar Read More. The frequency listed in the table shows the frequency at which the calculated skin depth is equal to the radius of the wire, and is an indication that above this frequency you should start considering the skin effect when calculating the wire's resistance. Wire gauge capacity. Entertainment Industrial Military. Selecting the appropriate wire size for a circuit is crucial to prevent overheating, which can lead to damage and fire hazards. Trailer controllers: interface 12V and 24V vehicles and trailers. To determine the gauge wire you need, consider what carrying capacity and amount of current the wire needs to conduct to work for your application. Wire gauge current. Contact your local electrician to find out what is legal! Choosing a wire size will depend on the gauge and length you need. This is why AWG wires are always slightly bigger in diameter than solid wire. Ampacity Chart.
