AWG线规对照表

  • 把英制的单位换算成了公制单位。
  • 另外特别解释一下『chassis wiring』&『power transmission』

They generally mean that "chassis wiring" is short-lengths and "open" (i.e. air-cooled, not bundled together and overwrapped with lots of insulation which prevents the wire from air-cooling). And "power transmission" means long distances, and bundled together (or pulled with other wires through a conduit pipe) which has a whole different set of factors to consider.
