Alternator wiring upgrade

I am pretty new here so this is my first thread. I was reading up on some older threads but have not found what I was looking for. I wanted to see if anyone else had an alternator putting out more than 200 amps and what new wiring is required to run such a beefy alternator.

You can look into this one. I believe there's quite a few but you can reference the info on here

 

Here you go. I don't know if you need to upgrade the wiring coming off of it. Doesn't mention it in the description so I would assume no.

I heard some people say that the wires could melt and burn if the alternator output was too high but thank you @EatSleepTacos & @Jimmy92870

 

Since you have the OR it should have the 130A alternator and as I recall a 140A fuse. Obviously, don't try to draw that extra current through the OEM fuse. Lots of good info in the aforementioned thread (and many others) regarding power distribution mods.

There's a voltage drop across the cable going from the alternator, it's linear with current so everything else being constant, it shouldn't be too bad.

(Addendum) Power is proportional to the square of current, so the power dissipated by the cable will be 2.37x with a 200A alternator vs. 130A, assuming that full amount of power is being drawn. The cable probably has a reasonable safety margin but you might decide that's enough of an increase to warrant switching to a beefier cable.

I find it very interesting to read about the realities of power distribution in a vehicle. I had always assumed that the frame/chassis provides low-resistance ground everywhere but it's not always the case.

Just stumbled across this and thought I'd share with you.
