new fusebox but on amp.

I fabbed up new fuse box for my camaro car Ls2 carbed without controlled programs (PCM) I forget, how figure to how much ampere fuse each on these 6 slots Slots:  Slots: 1) 12 ga. (12V hot) / 12 ga. = ? amp.       4) 16ga. (12V hot) / 16 ga. = ? amp 2) 12 ga. (12V hot)/ 10 ga. = ? amp.      5) 12 ga. (12V hot) / 10 ga. = ? amp 3) 10 ga. (12V hot) / 10 ga. = ? amp        6) 12 ga. (12V hot) / 12 ga. = ? amp Appreciate for help/advice.

Give me the calculator/formula to figure out how much the amp from volt and cable length? For example: 1) 12 ga. (12V hot)/ 12 ga. = should be 25 amp. @ 3 feet length. Is it correct? It goes to alternator (100AMP) from fuse box.

Look at the chart labeled Power and Ground Cable Specs. It gives you the current rating of each Gauge of wire. 12 Ga wire should be fused at no more than 40 amps. 16 Gauge a maximum of 15 amps.

My method is by formula: I decide what maximum voltage drop I desire. (Few cable rating tables state that. And if 3V is considered a tolerable voltage drop for a 12V system...) It's then Ohm's Law (V=IR) where R is the cable resistance per length times the length.

The chart I sent you to is just to show you the maximum safe current of each of the wire sizes. Just do not fuse at a greater current than on that chart.

Slots:  Slots: 1) 12 ga. (12V hot) / 12 ga. = ? amp.       4) 16ga. (12V hot) / 16 ga. = ? amp 2) 12 ga. (12V hot)/ 10 ga. = ? amp.        5) 12 ga. (12V hot) / 10 ga. = ? amp 3) 10 ga. (12V hot) / 10 ga. = ? amp        6) 12 ga. (12V hot) / 12 ga. = ? amp I figured those amps.. 1. 25 amp.> goes to ign. switch bat.+ 2. 25 amp.> headlight 3. 25 amp.> goes to Alternator 4. 15 amp.> alternator exciter 5. 20 amp.> ign. switch acc. 6. 25 amp.> cool dual fans?

1) at least 50 amps to cover all the ign starter and ACC wires. 2) 20 3)? 4)? 5) see no. 1. 6) Try about 60 for rad fans.

Easier to work out the load on what you're fusing then use the relevant wire gauge.
