1G battery relocation fuse size

[drcolt]

I have searched and havent found a best recommended fuse size for when relocating battery to trunk. I have noticed post with members running anywhere from 80amp to 200amp fuses.
I am relocating to trunk just because I cannot physically fit the newly swapped 90 4g63t motor and all other plumbing in my colt.
Being an electrician, we protect the wire at the main with the wire size amp rating. We then fuse the load at smaller respective fuses. It seems guys are doing different things whenever i run searches.
So running #1/0 wire, It should be fuse at 150amp or less.kRunning #1 wire, it should be fused at 130amp or less.

Or am I looking at this totally wrong?
I will be trying at #1awg cable fused at 100.
So to those that have a relocated setup, what are your fuse sizes at the trunk?

Id buy a few different ones as each car is different. Also have a a few on hand, just in case. I believe I ran a 150 with my zero gauge. What amp is your alt?

I tried a few different ones as well, 100 and 120 kept popping. Stepped up to a 150 and haven't had anymore issues. I'm running 0 gauge from the trunk as well. 90 AMP alternator.

Curiouse is the fuse between the battery and the harness... My fuse is only between the alternator and battery..

I believe my alternator is an 80amp. I will definetely be having various fuse sizes on hand.

Well, I bought a party pack of 100's and 150's. The first 100 held, and has been in since day one. It looks like I will leave it like that, seeing as #3awg is rated for 100amps, and I am running #2awg. The kit I bought was supposed to be #1/0. I was ripped off, but heck, its working.
