Always order big!
I needed a minimum of 2 AWG wire to create interconnects between batteries in a large bank. If you note, these say 1/0 Gauge, not AWG. What is 1/0 Gauge? Who knows, it's fake. Meaningless, because it is not standardized so you have no clue what you are getting.
What did I get for my 1/0 Gauge wire? Something that was in between 1 and 2 AWG (closer to 1). This was perfect for my needs because I knew darn well how big to order when they say gauge instead of AWG.
As a rule of thumb: If they as gauge, order 3 - 4 sizes larger than you need in AWG. This will always net you larger wire than you need but I have never had it net me wire smaller than I needed.
At the price I got it for during prime days, it was a steal for 2 AWG wire, so I win!
I hope you found this helpful!
