What is the diameter of 4 0 aluminum wire?

AWG refers to the American Wire Gauge standard, (also known as the Browne and Sharpe wire gauge) and it's been in common use since the 1800s. You may guess that 4/0 AWG is just another way to say 4 AWG, you'd be wrong. It goes like this. 4 AWG, 3 AWG, 2 AWG, 1 AWG, 0 AWG, 00 AWG, 000 AWG, 0000 AWG.

Four AWG battery cables should be used on power inverters rated up to 1500 watts and most commonly used on 900, 1000, 1100, 1200 watt inverters. Smaller sized inverters generally come with a short 6 AWG cable which is included with the inverter.

Voltage drop of the circuit conductors can be determined by multiplying the current of the circuit by the total resistance of the circuit conductors: VD = I x R.

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.

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.

“Twelve-gauge wire is good for 20 amps, 10-gauge wire is good for 30 amps, 8-gauge is good for 40 amps, and 6-gauge is good for 55 amps,” and “The circuit breaker or fuse is always sized to protect the conductor [wire].”

8 AWG may carry a maximum of 70 Amps in free air, or 50 Amps as part of a 3 conductor cable. David, if that cable is NM (Romex) then it actually cannot carry 50 amps.
