@Steve - you must be living under a rock if you have never heard of AWG, and really isn't anything implied by calling it so, other than it is the standard the US. LOL- leave it to the pompus Brits to think yours the "Standard Wire Gauge"!
@Steve: SWG means Standard Wire Gauge which defines the wire's diameter.
As you know, I'm from the UK, so I didn't even think about your reference to SWG in your blog -- but in the past I have run into the fact that no one here in the USA seems to know what it means. Over here, the little scamps use AWG (American Wire Gauge) -- it's so cute when they try to re-invent something and stick the word "American" in front of it as though to imply that their wire gauge is better than anyone elses LOL
