no 2/0 for a good reason?

so far as i can tell nobody uses 2/0 (or bigger) for power wires, is their a reason behind this other than their is no terminals for it? or is it completely unnecessary? although i have seen some vehicles that use multiple 1/0 (i think) runs, why not run less of something bigger?

not that my system may need 2/0 but i figure why not when its cheap, just arc welder cable.

for reference i am running a zapco 1100.1, 350.2 and 360.4 i am defiantly getting 1/0 but i am seriously considering 2/0, im just stuck on how to terminate it, i can always drill distro blocks bigger i guess.

Terminals for wire that size you can pick up at any speciaty autoparts store (autopac/Tichborne) or even at Princess Auto and any welding shop

Changing the size of your power wire doesn't change your class in any of the major orgs. (except for IASCA .. but they're weird)...

btw.. I run 4/0 power and ground in my competition vehicle. It's just that the wire is a lot harder to find than 1/0 or 2/0 so most people don't bother. (plus it's a bitch to work with)

well, i have ended up going with 2/0, i found a local welding supply place in markham, it was $50 for 15ft which i think was a pretty good deal. he said he could get up to 4/0. now after doing the big 3 i shall see if my lights still dim.

I'm currently using 2/0, but I'll probably go bigger this season (however I may not need to).

I bleieve I got 30 feet for 85 dollars, so I'd say you got a pretty good deal.

moving onto another question that has come into my mind, the zapco specs for the 1100.1 don't seem to line up properly, it says to use 3 30A fuses (90 total) and then it goes on saying that max current requirements is 135A at 900W. so how the heck is it ever supposed to draw 135A when the fuses will blow at 90A?

and to get the 1100W (rms?) at 2Ohm it had to be something like 85% efficient at 14.4 volt.

You can get 1 ought and bigger at most electrical supply stores cut to the length you want. I get pretty good discounts on that stuff, say I wanted to run a length for power and ground in 1 ought, would it make a difference to use the stranded stuff from my supplier?
