2/0 + gauge wire ?


Recommended Posts

And while I'm on a roll here: keep in mind that lots of car audio wire is oversized. For example, KnuKonceptz Kolossus Fleks is made up of 5145 strands of 36 gauge. Which gives it a cross sectional area of 65.3sqmm - making it roughly equivalent to 2/0.

ah ok sounds good. also as I've been looking I've noticed that the charts that say the amp capacity for a particular wire most of them don't match... and all of them put 1/0 gauge at under 250 and most put it under 150 but I've been told that a single run of 1/0 was fine on up to I think they said 300 something... anyone have a chart that accurately says the amp capacity of different gauges?

IMO amp capacity is all based on how long your runs are

You can look at this. That's the most amount the wire can carry safely, regardless of length. Look under the "chassis wiring" column

Here is what I use. Ideally, try and keep your voltage drop below 5. 2-3% being preferable

ok thank you. so going by that my 270A+ alt (haven't bought it yet but 270 is the biggest I've found so far, currently looking for bigger if I can find one) actually should probably ideally have more than a single 1/0 gauge wire correct?

EDIT - and probably smaller than a 320A fuse

Thanks I was pretty excited about the alt myself. kind of like a school girl, in a dress, on a swing. lol

It's warming up enough that the donut-punching cyclist douchenozzles are getting their two wheeled fagmobiles out.

Correct. I have 2 for my alt. A third one going in too

technically speaking though copper is copper. :)

Except you have different kinds of copper, hard or soft copper as a example.

Multiple runs should be easier to do then a huge wire.

In reference to current flow. Not copper density.

Ok thanks I'll keep that in mind when i do my upgrade
