Under hood fuse holder

[Babs]

What size wire ( 2 awg )?

Everything battery-side of the distribution block is 1/0.. That's what I had.
I recently re-ran the car wiring and re-did the under-hood setup, replacing 4awg with the 1/0.
The short runs (power and ground) from the distribution block to amps is 4awg.
Don't believe I've ever messed with 2awg.. Would have likely been fine as well.

1/0 is excellent & more expensive than some systems ! HaHa
