Sergeant_Skyrim Posted April 4, 2012 Author Report Share Posted April 4, 2012 Alrighty then, guess I'll be ordering up 50 feet of 1/0 welding cable! Thanks for the input everybody =) Quote Build in progress Link to comment Share on other sites More sharing options...
HunterJohnson Posted April 4, 2012 Report Share Posted April 4, 2012 Came across what looks to be some good priced welding cable...does this seem like a good substitute for 0 gauge? https://weldingsuppl...OR:terms::PA#A2 Welding cable is great stuff as long as its ofc. its gonna be a little less flexible but still I'd use it. If youre short on cash get knukonceptz CCA 50ft spool for less than 100. Its cheaper than welding cable Wouldn't the OFC welding cable be better than CCA? YUP!

Amart88 Posted April 4, 2012 Report Share Posted April 4, 2012 I have 25 feet of that Cadence 0 ga. its really flexable and is a good size but I heard its CCA not OFC even though it says OFC, I like the Knu OFC. Quality welding cable would be good too. as long as its ofc Quote My 2005 s10 blazer build. 4 zcon 18's walled. Link to comment Share on other sites More sharing options...

If youre short on cash get knukonceptz CCA 50ft spool for less than 100. Its cheaper than welding cable Wouldn't the OFC welding cable be better than CCA? If they are the same size, yes. Copper is about 1.5 times as conductive as aluminum So OFC figure OFC is around 1.4 times as conductive as CCA But, consider that KNU is oversized. According to the AWG spec, KNU 1/0 has a .45 inch conductor diameter, which puts it at just below 4/0 wire I will round down to 3/0 for this though 1/0 has 53.5sqmm of cross sectional area, and 3/0 has 85.0sqmm of area. This gives the KNU KCA wire around 55% more area than 1/0. ~50% more surface area, ~50% less conductive. So KNU KCA should be just as conductive as OFC welding cable. You decide if you want to deal with trying to fit 3/0 in 1/0 terminals. There should be no difference between the conductivity of KNU CCA and OFC welding cable.

The only thing I don't like about the cca is it does get hotter than OFC which means there's resistance, but technically it should be the same resistance so????

Sergeant_Skyrim Posted April 4, 2012 Author Report Share Posted April 4, 2012 Pretty informative stuff here definitely a great read. Sending in a order for 50 feet of the welding cable as we speak! Quote Build in progress Link to comment Share on other sites More sharing options...
Autruche Posted April 4, 2012 Report Share Posted April 4, 2012 SnowDrifter pretty much hit the nail on the head. CCA is about 66% as conductive as the same sized OFC wire would be. Knu may oversize their wire, but if it fits into a 2/0 lug, that's only proof that it still isn't good enough. OFC > CCA any day, every day Oh, and Knu doesn't have any OFC wire. Their "OFC" is tinned. Last time I checked, tin isn't copper and therefore it isn't OFC wire. Quote Need Test Tones/Sine Waves?

So that's why it was such a pain in the ass to get it into the 1/0 connectors I had lol. I agree with the Knu CCA if your on a budget. I used it for my big three and have had no problems. Still noticed a solid 1~2/10ths of a volt higher. The rubber jacket does seem kind of thin in my opinion tho... Just ordered 36' of xscorpion 0ga from darvex. Ill let you know how it is when it gets here tomorrow!
