A. 1\0 guage wire is the same thing as 0 guage wire. wire thickness goes from higher numbers (like 32awg) down to 0000 guage (ie; 4ott wire, 4\0 guage). its pretty much like saying -4 guage wire. lol //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif
and usually the people using 4\0 have custom distroblocks that are made with slabs of brass with bolts on them. and they dont use fuses because they are in competition and frying 4\0 wire is extremly hard heh.
