Stranded wire gauges should be measured by calculating the equivalent cross sectional copper area. First, measure the bare diameter of a single strand and locate the circular mils value in the row that matches your measurement. Second, multiply the circular mils by the number of strands in the cable.

Ear Gauge to MM Conversion Table

Gauge | Millimeters(mm) | Inches |

14g | 1.6 mm | 1/16″ |

12g | 2 mm | 5/64″ |

10g | 2.4 mm | 3/32″ |

8g | 3.2 mm | 1/8″ |

Secondly, how do you determine wire gauge size? Stranded **wire gauges** should be measured by calculating the equivalent cross sectional copper area. First, **measure** the bare **diameter** of a single strand and locate the circular mils value in the row that matches your measurement. Second, multiply the circular mils by the number of strands in the **cable**.

### What size wire do I need for 30 amps?

Any circuit fused for 30 amps must use a minimum of 10 ga copper or 8 ga alu. Longer runs may require an upgrade of wire size. In your case, use at least 10 copper for your welder regardless how far it is from the breaker panel.

### Can 10 gauge wire handle 35 amps?

To put it simply though, maybe, depending on insulation type and/or designed operational temperature 10 gauge can handle anywhere from 30 – 40 amperes if it is copper and 25 – 35 amperes if it is aluminum. There are some restrictions on the high end which you will need to observe if you are going by the NEC.

### What size wire do I need for 50 amps?

For a 50-amp aluminum wire, use No. 4 AWG. The smaller the number on the wire, the larger the wire diameter.
