use 4 gauge spade crimp connectors
4 gauge
250 amps maximum.
2 or 4
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.
Far as I know it's just size of wire, smaller the gauge the thicker the wire. which means the 4 is going to be thicker than the 8.
at least 4ga wire but it would be best to get 4awg or 0awg. 4 gauge is smaller than 4 American gauge wire
the answer is gauge its a measurement of thickness in wire the 4 gauge (ga) wire ran from my car battery to power my audio amp. the smaller the number the bigger the wire usually from 24 gauge to 1/0 gauge which is about a inch thick
AWG # 4 copper.
That is not home wiring. I would use 4/00 gauge. <<>> A 750MCM wire with an insulation factor of 90 degrees C is rated at 500 amps. A parallel run of two 500MCM will give you 1000 amp capacity.
8 gauge is very common and really all youll need but i prefer 4 gauge its alittle more spendy but its good. make sure the amp wire holders will fit 4 gauge if you go with that.
minimum gauge is 6 and the best is 4
