[QUOTE="wevie, post: 5205932, member: 603871"] Interesting question. #8=16484mcm (mil circular mils) #7=20770mcm #6=26170mcm #5=32974mcm #4=41548mcm #3=52350mcm #2=65961mcm #1=83111mcm #0=104720mcm So, 2x#4 would give you 83096 mcm which is darn near #1. And, #4 has a rated* current flow of 131 amps. #1 has a rated current flow of......262 amps (surprise!!). *the amount of current flow which will cause a 1/2 volt drop in a 15 foot run of cable Recommended fuse size: #4 = 125, #1 = 250, and 0 = 325 So, no, two runs of 4AWG is NOT equivalent to one run of 0. Edit: and another calculation: 70% efficient Class D amp at 13.8 volts with 1AWG wire, 15 ft. long comes out to a maximum of 2529 amplifier watts. If you are running nothing except the Herc at 1 ohm, you might be OK. [/QUOTE]
