Although it seems like a strange system, it is designed so that the wire area approximately doubles for every three steps on the gauge scale.įor AWG-metric conversions for the most common sizes of wire, see the chart below. There are also 39 gauge sizes in between. In other international countries, conductors are measured using their cross-section, which is given in square millimeters.ĪWG: In the American Wire Gauge system, 36 AWG wire has a 0.0050-inch diameter. One MCM is equivalent to 1,000 circular mils.įor Britain and Canada, a system called the British Standard Wire Gauge (SWG) is the measurement system of choice. For larger wires, circular mils are used. MCM sizes, also called kcmils (kilo-circular mils), are for even larger cables. With the gauge system, the higher the number is, the smaller the cable will be. In the United States, smaller conductors are measured using the American Wire Gauge (AWG). When purchasing a wire or cable, it is important to understand the differences in sizes to ensure your application performs at its best. In the same vein, you might wonder what MCM means in terms of wire size. A wire with a diameter of 200 mils is 40 MCM. Multi-Conductor Control and Power CableĪ conductor’s size has a huge effect on a cable’s or application’s performance. MCM stands for thousands of circular mils, which is an old wire gauge measurement.XLPE/XL-CPE with Overall Shielded Pairs/Triads.XLPE/XL-CPE with Individual and Overall Shielded Pairs/Triads.XLPE/XL-CPE with Individual and Overall Shielded Pairs.XLPE/PVC with Overall Shielded Pairs/Triads.XLPE/PVC with Individual and Overall Shielded Pairs.XLPE/Arctic-Grade PVC with Overall Shielded Pairs/Triads.XLPE/Arctic-Grade PVC with Individual and Overall Shielded Pairs.VNTC - PVC/Nylon/PVC with Overall Shielded Pairs/Triads.If you require larger MM to AWG sizes converted, please send in a request.
