Wire/cable for Engine bay

Would like some suggestion on the best type of wire ( 2 - 2/0 gauge ) to use in the engine bay.

I go by how much current is going to be running through any particular wire and kick it up a notch to the next higher rated gauge if needed.

 

What are you using it for? #2 and 2/0 is huge. My guess is anything you are going to run will need nothing more than #12 and possibly/probably smaller.

 

Yeah, my freakin main winch cables are 0. ^^^^^

 

I am asking the type of cable. Would welding cable be better or wiring that can handle heat and grease? Just asking for suggestions on what people had the best experience with. There is a lot of information on the web but still, want real user input.

Kurt, what is the application for? Sounds like you are more interested in the wire jacket than the size of conductor.

 

Yes, my concern is about the jacketing but the size will be at least 2 gauge wiring which will run from the engine bay to the bed of the truck. I know welding cable is very flexible (at the larger gauge wiring) and can handle high volts/amps but can it take the heat and grease of the engine bay and road. I know I can run the cable through wire looms to add additional protection. Just looking for Tundra owners input on their experience with running large wires from the battery to other parts of their truck.

At my shop we use welding wire. 100% copper strand with a oil / uv resistant silicone jacket. Gauge size is dependent on voltage needed and length of run. Welding wire seems to be the easiest to bend and maneuver. Regardless of the jacket, I always loom the wire and wrap with cloth electrical tape for abrasion and weather resistance. And if I absolutely can't avoid a high heat area I use heat reflective tape. Hope that helps.

 

Yes, that does help. @duece292 who do you use for your supplier.

We use Del City. They're a WD / jobber supplier for pretty much anything aotomtive electrical.
