Question

Yesterday I couldn't find connectors for 2AWG cable at my local stereo shop, so I checked out an Electrozad shop (supplies for industry)....

The connectors that fit 2AWG were marked 3/0.... [img]graemlins/dunno.gif[/img]

Aaargh...I hate how some companies rate their wires. A friend bought 2 ga on Ebay and it was smaller than my 4 ga. Uber gay. Sorry, rant over.

It's possible that the wires were rated using the diameter of the wire including insulation ...

^ that would seem pretty fing stupid to me... lol...

I don't know what kind of 2awg would have insulation thick enough to make it compairable to some other 3/0 wire ether.... maybe stuff that's rated for 50,000V.... [img]graemlins/freak.gif[/img]

Anyway, I'll also mention the day I noticed my 8ga lighning audio wire was substanitally smaller then some crank'n cable 8ga wire...

further investigation showed that only the 2" ground wire included in my '8AWG wiring kit' was actually 8AWG... [img]graemlins/puke.gif[/img]

I use industrial or welding cable.. since THOSE industries are standardized.


there can be a huge difference between "8 guage" and "8 awg" AWG stands for American Wire Guage, which is an international standard for wire size measurement. "guage" means precisely jack ****e.

The reason your #2 wire fit into a 3/0 lug, is because the 3/0 lug is made for 19 strand industrial wire, not flexible or superflexible wire, which has many more strands and much more wasted space in it. We actually ran into this at work today... the 1/0 welding cable leading ot a transformer wouldn't fit into tyhe 1/0 lugs on the transformer, so the lugs had to be switched out to 250 kCmil lugs to get the wire to fit.
