Overkill for what i need, Rocket industries are pricey.
Thats because your into car audio, they all use AWG. So much trend for following Americans. Standard building wire, either in solid or stranded core as an Australian standard not in the Automotive industry is done in mm2. Why am i using mm2 wire? Because its what i use everyday, i know what each size cable is rated too and i get it for free. Why would i use AWG?
Not entirely true. The very cheap cable becomes brittle and deteriorates quickly. You shouldn't be running wiring in an area of the engine bay where its stupidly hot anyway.
Ok, umm this is stupid quote of the day, AC and DC have different electrical characteristics yes. If you think for one second that DC won't kill you, you a dead wrong buddy. DC is more dangerous than AC in the fact that DC Causes your muscles to contract and will not let you un-contract. Your muscles overheat very quickly and begin to burn up. You then begin to spasm. DC will give you a friggen boot so painful you won't know what the hell happened.
Ahh but you say i can touch a 12V battery, both terminals no problem. Thats because you need approximately 50V DC or AC to penetrate your high resistive skin. 50 - 100mA of current (AC OR DC) passing directly over your heart is enough to kill you. At around 40mA your heart begins to fibrillate (makes your heart go out of time) causing very bad chest pain. After this, most people's heart fail and they die. This is electrocution.
AC current goes from peak high, back through zero to peak low 50 times a second here in Australia (50Hz), this causes the muscles to contract - un contract and so on. A person is usually able to let go or move away from the source that is giving them the electric shock.
At the end of the day, it doesn't matter if its AC or DC or even what voltage it is. It is the CURRENT that kills you. Although, the higher the voltage, the MUCH easier it is for you to receive an electric shock or die. The higher the voltage, the easier it is for current to pass through you. In voltages that in the high kV area, if your on the ground and you get close to one of the conductors, you dont even need to touch it, the high voltage will jump the gap, travel through you down to earth, killing and vaporising you at the same time.
And you said your an electronics engineer? I would have thought you should know a lot about this...

This is a man in India, that dies from his body coming into contact with the overhead DC conductor. Yes, DC is dangerous and not to be treated lightly.
When i am working around a battery bank that is above 48VDC it worries me more than working around 400VAC three phase.
This one is a no brainer....
Maybe viable.
