Is 90A worth of fuses on a 90A alt. okay?

As the title states: The total fuse rating from my amps = 90A. I have a 90A alternator.

Am I gonna need the big 3 or an alt. upgrade?

What size is that amp? Around 1000 watts?

You'll be fine, I have the capability to pull well over twice what my alt is capable of, and I'm fine. Batts in the back ftw

Fuse what the WIRE is rated at.

^ that's the best solution, imo.

Fuse rating has no relation to actual current draw.

The amps are in my sig, so ~800 watts

Sorry for the ignorance. But I thought I saw a formula w/ the fuse ratings as the determining factor as to if it would be able to handle such a draw //content.invisioncic.com/y282845/emoticons/blush.gif.99bc659ee2012b7d826165e26fb5eebe.gif//content.invisioncic.com/y282845/emoticons/*******.gif.a649d21efc0d1fd4890a6428166586c1.gif

Any formula for current draw is going to be nothing more than a WAG (wild a$$ guess if you aren't familiar with the acronym). You can get an idea of the max current draw but that is largely irrelevant for daily usage.
