I would take those charts with a pinch of salt for our applications, since we are normally using silicone cables and only running for very short lengths of time. Best bet is to try running at full tilt for a realistic amount of time and check how hot everything gets.

For example Triforce runs 6AWG silicone cable at about 400A (2x 150cc rotomax), but since it only pulls that for less than 10s it is fine, we use 2x 200A Mega fuses in parallel to protect from battery shorts.

Yes I completely agree take them with a pinch of salt! With silicone insulation you've just moved the tolerable cable temperatures from about 80deg C to about 160deg C. Temperature of all components is as you say the important aspect.

My point was that you're protecting more than just the battery and the fuse should match the lowest performing thing, unless it's expendable
