2 or 4
on a 4000 watt amp the best gauge wire woul be between 2 and 0
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.
For a 30 amp breaker, you will need a wire that is at least 10 gauge in size.
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.
For a dryer installation, you typically need a 10-gauge wire.
The gauge of wire you need for your project depends on the amount of current it will carry. Thicker wire has a lower gauge number and can carry more current. Consult a wire gauge chart to determine the appropriate size for your specific project.
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
For a 50 amp breaker, you will need a wire that is at least 6 gauge in size to safely handle the electrical load.
