Wires come in standard sizes that are linked to the amount of current that they can safely carry given the conditions in which they will be used (see wire ampacity). When choosing a wire size for a circuit it is also important to consider the voltage drop that the circuit will experience under operation. The two most common standards for wire size are American Wire Gauge (AWG) and mm². These two systems are not directly equivalent.
Standard AWG | Metric equivalent | Standard metric equivalent (mm) |
---|---|---|
18AWG | .82mm² | 1mm² |
16 AWG | 1.31mm² | 1.5mm² |
14 AWG | 2.08mm² | 2.5mm² |
12AWG | 3.31mm² | 4mm² |
10 AWG | 5.26mm² | 6mm² |
8 AWG | 8.37mm² | 10mm² |
6 AWG | 13.3mm² | 16mm² |
4 AWG | 21.2mm² | 25mm² |
3 AWG | 26.7mm² | |
2 AWG | 33.6mm² | 35mm² |
1 AWG | 42.4mm² | 50mm² |
1/0 AWG | 53.5mm² | |
2/0 AWG | 67.4mm² | 70mm² |
3/0 AWG | 85mm² | 95mm² |
4/0 AWG | 107mm² | 120mm² |
