12 gauge speaker wire diameter

Speed,

Maybe you need to do some research.

I’d last a week on a manufacturing floor using your “right” AWG tables as you would fail UL444 max DCR in stranded and processed cables. There is ONLY one RIGHT and that is UL444! Don’t pass that and you can’t label your product. Yes, UL444 is structured after the AWG tables but the DO NOT spec “exact” wire sizes, ever.

AWG tables are a STARTING point for UL444, and UL knows processing will vary the SIZE per twisted pair lay stranding length and other processes, so an average size range is devised to account for this. A DCR max spec is the final judge where multiple pairs are tested using automated test equipment that measures DCR. A laser mic or table never touches the product.

Please be helpful, your tone is not helpful. You general information is, but it isn’t “all” right as the AWG tables are just a starting point reference. No more. I grabbed a generic size to go through the math (use your own values if you will, makes no difference). The PROCESS is what is shown.

What we also know, is 0.0808" as right as it is on paper, is useless in real manufacture.

Best,
Galen Gareis
