when i think of gauge size, that would be the tube space the pencils and toothpicks fit inside of
This is all I'm saying....
I work for an electric utility. If strand count was what was important, then tell me, enlighten me, why do our 1/0 cables, which carry 23,000 volts, only have 7 strands?
I see your theory, and thus debunk it.
Higher strand count is only good for flexibility. Thats it and thats all.
7 strands of 8 gauge wire
scroll to Stranded v.s Solid wire, then scroll down to Duration of Usage
Even Wikipedia (under Forms of Wire) says Higher Stranded wire conducts better than a Solid wire because of the Surface Area. It further states Solid wire is cheaper to manufacture and has more ruggedness, .....so why wouldn't they be used in voltage lines to save $$$ and be durable to weather and be less corossive because of LESS surface area.
Believe what we have here is a misunderstanding between
a " Better Conductor" v.s. "Duration of Usage",
So we have established Higher Stranded wire is in fact a Better conductor and it is more Flexible for precise placement applications.

Rock on @madmike1157
I think I can appropriately use now?!
So it's you, and the guy that drives the German Chevrolet with the hard heads?
You're using a cable that when bent, stays bent as the end all "proof" of your claim to posses the Golden Child of Conductivity award?
Your electrical utility company is somehow the end all authority based on their usage of a certain cable then?
Your utility company uses 7 conductor cable because it's cheaper to make.
( And now that I think of it, aren't electrical utility companies the same guys that used aluminum wire for however many years as a safe alternative to copper before it was banned)
Just because you can push a bazillion volts through a conductor doesn't take into account how many amps it took to push it through.
And for the record, expert utility company worker, we're not talking about 23,000 volts, we're talking about 12. and at the same time, were not talking about AC either,..were talking DC. However, I'm not sure the last even matters.
The whole crux of the argument is whether or not the advance cable has more strands than a welding cable rated at the same size.
Whether or not you accept that more copper strands in a jacket are more efficient at moving more current at less amperage while maintaining flexibility and durability required for an automotive application is your perogative,...... but please don't cite some bogus example as your "proof" and claim it as a debunk to what I'm saying.
Actually I was pointing out that flexibility is the only benefit to the higher strand wires. Conductivity is negligible when you compare a 7 strand to a 19, 37, 49 or eleventy billion strand.
And I'm sorry, but I have a big problem with this statement.
Amperage IS current. You can't move more CURRENT with less AMPS, they are the same thing.
All this being said, for automotive use, stranded wire is the best. If you need it to be super flexible, use a higher strand count.
Also, I'm not sure where this comes from:
I'm going to assume you are refering to Al wire being used in home wiring. If so, there is no electric utility that I am aware of in the USA that does internal home wiring. So in short, no, they are not the same guys.
Pass the popcorn please
Extra butter movie style of kettle corn? @madspeed maybe pass the wild mountain gourmet popcorn???
Its common knowledge that welding cable of the same gauge of battery cable has a higher strand count thus why its more flexible than standard battery cable
Thus contradicting your very first statement
"It's all about strand count when you are buying a cable intended for an automotive application versus a ground cable for a stick welder. The more and finer strands the better in this case"
This is also why welding cable of the same gauge as battery cable has a larger diameter
As to your theory on conductivity that only applies to high frequency ie. radio frequency or microwave and isn't a factor with 12v DC
Now the only thing that truly matters is using the proper size for the distance your going.
Since we're quoting here, when I read this^^^^, I take it when he says "versus" it's meaning "compared too" which means compared to welding ground cable and it's the darn close or near the same or same (because it does have a high strand count) with BETTER resistance to oil, dirt etc as stated before. He even states the principle of higher strands being better for the application of conductivity. And when looking for an Advanced Auto store that sells it "OFF a ROLL" and "NOT the pre-made ground cable" that certain ones keep referring too. Tells me it's WAY more convenient to find a store and it has ALL the benefits of welding wire, because it's a HIGH strand wire. So WHO would know this piece of nugget, someone with experience that's been there done that and got a t-shirt. Clearly his advice was WAY more helpful to anyone trying to better a project from the begining
I personally have never had a problem with flexibility with any battery cable. Good grief, are we trying to tie figure 8 knots with battery cable? Where in an automotive application does a battery cable make a 180 degree turn virtually upon itself? None that I know of, and I have worked on virtually every kind of car ever built for the last 30 plus years, from 6 volt positive ground to 24 volt diesel applications. I have yet to see where a battery cable off of any parts house shelf could not make the proper routing because of lack of flexibility, given the correct gauge for the application. The current argument is a matter of semantics, just buy the right gauge for the proper distance and amps usage and strand count will mean nothing.
enough strands here?
