1/0 welding cable cheap

^ And the Canadian Electrical Code is to be used in conjunction with the Canadian BUILDING Code.
It does not carry over to a vehicle. As mentioned - car audio equipment does not carry CSA labelling.
Hardwrkr - welding cable often has a neoprene jacket on it. Neoprene has poor resistance to diesel and gasoline - they will cause the neoprene to swell and weaken. Unless you soak the cable with either I would not worry about it. Simple plastic split loom would eliminate all but the most bizarre problems.
[img]graemlins/freak.gif[/img] First off, solid wire would be best but most people would not be able to manage working with it. After that, the more strands the better. The more strands, the closer they pack together and the less free area that is not copper. Take a 1/0 cable and consider round cross section strands. Would you rather have say, 4 strands in there or 7. 7 as they nest together better and have less free area in between the stands. Now, would you rather have 7 or 4700? The answer is obvious. The 4700 strands pack together closer and mimick a solid cable.
To relate the same to the corrosion issue. in the 4strand per cable wire the contact area between the strands is minimal. The rest of the strands' surface is free to corrode but the areas that the strands touch each other will not. Similarly, the 4700 strands if tightly bundled which most polymer jacketed cables are will exhibit corrosion around the outer perimiter with some minor penetration arount the perimiter, and some capilliary corrosion near the open end across the cross section of the cable. If you take a shooter glass and look at the cross section of it, that is the corrosion pattern a stranded cable takes on.
This is easily avoided by heatshrinking connections and, if using open end terminals, soldering the end strands or packing them with grease.
Crappy cables (re: factory ones) have loosely bundled strands with poor end treatments, and fragile jackets that break down over time so they invite corrosion.

More strands means more DC resistance... it should be obvious why... and no skin effect dosent have anything to do with it....
Now we arnt talking a huge difference here... however as strand count increases so does surface to area ratio of the wire which makes it more prone to corrosion.... its not uncommon to take old wire from under the hood of a vehicle and find not only corrosion through the strands at the connection, but up under the jaket as well... sometimes several inches up!

ACtaully, the Canadian electrical code covers ALL elctrical installations in canada, with the exception of ships, mines and a couple other small exceptions. technically, vehicles are covered.
More strands do have less ESR.
Corrosion can be lessened by using a cable that is tinned. Many cables now are are 'tinned' for cosmetic reasons and the other benefit is that they do not corrode like bare copper.
Dukk, good post!

I will get some big 3 phase power cable and you can try and run it through a car [img]graemlins/thumb.gif[/img]

I have used welding cable in my vehicle before and let me tell you it sucked. The rubber jacket does not do a good job of resisting moisture. The copper wire turned green and frayed. Don't cheap out because you will just end up paying more in the long run.

try haveing 10 runs for positive and 10 runs of ground wire from front to back of your car! [img]smile.gif[/img] now that's alot of 1/0 welding cable... about 150lbs worth! [img]graemlins/freak.gif[/img]
