Wire gauge recommendation

Wire size can be measured in several ways. We could speak of a wire’s diameter, but since its really the cross-sectional area that matters most regarding the flow of electrons, we are better off designating wire size in terms of area.

"For electrical conductor sizing, the American Wire Gauge (AWG), also known as the Brown and Sharpe (B&S) gauge, is the measurement system of choice".

Out of the very article you posted. Once again what is your point?

Wire size graph

What a mess of BBCodes! And that graph is pathetic. Use a real calculator.

Thanks for the rude comment. The link was suppose to go to a image that shows amerpage and length vs. wire size.

You still here johnm1?

You are comparing diameter instead of the cross section area.
With cross section area you can compare to a copper pipe or a solid copper bar.
area = (pi)r² giving an exponential relationship between diameter and area.

Two wires next to each other one inch wide is not the same as a single one inch diameter wire.

On your chart use the area columns to add and compare.

Apples to apples I'm not talking about a pipe or a solid bar am I??

No parallel wire when roping a house right?

I mean if you ran out of #6 or #8 for the air conditioner you don't pull 2x #10.

I understand what you are saying with the #2 and #6. Just not my style.

So..... What you are saying is the rules for 230/120 AC are the same as 12 volt DC??? Really? Stick your fingers on the power wires of a 230 or 120 AC line and if you are still alive put your finger in a 12 DC power port and tell me which one is dangerous???

Crunching the numbers 14.6 volts 75 amps 14 foot (28 total using 6awg) shows a voltage drop of 5.68% (.83 volts) adding a 4awg to the 6awg would a bit larger then 2/0 awg and a voltage drop of 1.10% (.16).
It would likely be cheaper and more effective to move the converter. Can you?

2/0 133,100 cm
#6 26,600 cm
#4 42,000 cm
#2 66,500 cm

#6 + #4 looks more like #2 than 2/0.

OK how is this?

Inches. MM
#4 0.2043 5.189
#6 0.1620 4.115

0.3663 9.304

#00
2/0 0.3648 9.266


Hmmm not the same is it?

One thing is sure I would NEVER buy sub size wire from the URL you listed. Yet another source
