500 mcm
Look i have a 5500 watt power acustic amp and its saids not to use nothing under 0 gauge. So use that thicker wirer mean better performance. Try it!!
No, a pencil is not a size 0 gauge size but a 4 gauge.
If you want to go from a 14st gauge to a 12st gauge, you need larger sizes needles.
You should use a 4 guage wire. There is a handy chart located at http://www.the12volt.com/info/recwirsz.asp which lists the proper wire size for differing wattages.
20 amp
Need to know the year and engine size.
You need a 60 amp breaker.
The size gauge that can be compared to tat of a pencil is a 4 gauge.
The maximum amperage it can carry for power transmission is .92 amps.
a lot if u want to get size 10 gauge u should get the normal ear piercing size which is a size 20 or 18 gauge and slowly gauge it to a size 10 gauge
