American Wire Gauge (AWG) is a number that gives the thickness (mm) and the flat area (mm2) of the wires. The higher the number the thinner the wire.
The summary of the typical AWG sizes, their corresponding variants in mm, corresponding sizes in Europe (EU mm2) and the continued permissible load in Amps (A).
AWG 0 (1/0) – 53.47 mm2 – EU 50 mm2 - 200 A
AGW 2 – 33.63 mm2 – EU 35 mm2 – 140 A
AWG 5 – 16.77 mm2 - EU 16 mm2 – 64 A
AWG 7 – 10.55 mm2 – EU 10 mm2 – 40 A
AWG 9 – 6.63 mm2 – EU 6 mm2 – 24 A
AWG 11 – 4.17 mm2 – EU 4 mm2 – 16 A
AWG 13 – 2.62 mm2 – EU 2.5 mm2 – 10 A
AWG 14 – 2.08 mm2 – EU 2 mm2 – 8 A
AWG 15 – 1.65 mm2 – EU 1.5 mm2 – 6 A
AWG 17 - 1,04 mm2 – EU 1 mm2 – 4 A
AWG 20 – 0.51 mm2 – EU 0.5 mm2 – 2 A
For current loads we use the 4 – 6 – 8 Amp rule.
This rule says that it is OK and fully safe to have 4 Amps for every 1 mm2 of a quality copper wire. It is also possible to load 6 Amps for every 1 mm2 especially for short time loads (in minutes). For peak currents the load of 8 Amps for every 1 mm2 is permissible only for individual wires in open area for very short time (in seconds).
