CROSS-REFERENCE - AWG TO METRIC SIZE (WITH AMPACITY) OF INSULATED CONDUCTORS

Temperature Rating Based on Insulation Type

Copper Aluminum or Copper-clad Aluminum

Wire Size

Note: Given values for wire sizes are not equivalents but give the nearest commercially available sizes between AWG and Metric standards Quantities

before the " | " is for AWG/MCM and those after the vertical bar is for Metric System. The table is most useful when available wire sizes are in Metric

System (mm2) but design specifications are given in AWG or conversely. Ampacities may overlap between AWG-Metric wire sizes using certain insulation

types. Due consideration must be practiced in selecting conductor size based on the nearest ampacity such that greater margin of safety is achieved (say,

by choosing wire size which has one step higher ampacity). Ampacities applicable to not more than three conductors are in raceway, cable, or earth,

rated up to 2000 V and at ambient temperature of 30°C. MCM is the same as kcmil . MCM to mm² conversion can use the relationship 1 kcmil =

0.5067 mm².
