hi guys, just need your input..about this :

24 AWG 7/32 tinned copper drain wire

7/32 is for what is it the number of wires or what?

sorry if the question seems a bit odd, just need to know.. thanks...

It means that it's a bundle of 7 strands of 32 gauge wires; such a bundle has the same cross-sectional area as a single strand of 24 gauge.

thank you... is there any link you can recommend for information like this things...

Wire gauges are easy to check as to diameter and ampacity. The number of strands is up to the manufacturer, and their spec for that particular wire is the source of information.

> What was the advantage of this "unit"?

According to the chain mail people,


The AWG system was developed in America to be used for electrical applications, and is still used for non-ferrous wire. (Ferrous means iron-based.) The gauge numbers are based on electrical resistance, which increases as the wire gets thinner. (Picture the electrons flowing through the wire as a bunch of people running down a hallway. If the wire/hallway gets thinner, it slows them down since there's not as much room for them to get through. That's what resistance is.) When the gauge number increases by 3, the higher (thinner) wire will have twice the resistance of the lower (thicker) wire. A general rule of thumb says that when the gauge goes up by 6, the wire diameter is halved. (So, for example, 22g would be roughly half as thick as 16g.)

Interesting article but the big question is why? Advantage? I'll guess I never will have the answer here.
