The equation that is used to figure this out is known as OHM's Law. P=Watts : I=Current : E=Voltage. You are looking for Watts so the equation is..... (I)(E) or I times E. 12Volts X 80A=960Watts.

Here are the formulas used in Ohm's Law:

P divided by I = E

P divided by E = I

I multiplied by E = P

These are the basic formulas that are used to figure out what you wanted to know. There are many more in Ohm's Law.

Hope this helps.

eh even that is a kinda bad guide line to go by

you want your fuse to match what you are doing

if this is for power wire ,you want to match what your wire is rated for

same if its a max fuse for an amp

if it takes an 80amp but the amp states 1200rms dont replace the 80 amp with a larger fuse

Ohm's Law is not a guide line. It defines the relationships between (P) power, (E) voltage, (I) current, and ® resistance.

I do agree that the fuse should be matched or rated below the capacity of the wire that it protects.

Common sense would hopefully prevail when replacing the fuse on/in an amplifier. The manufacturer's specs should be referenced whenever the fuse is replaced.

it saddens me how few people try to search before asking simple questions... //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

I ran 1100 rms on an 80 amp fuse for years.

Looks like someone forgot about efficiency

yea man i for got. i searched but nothing came up about what it could hold.

i think the better question is "How much current will an 80amp fuse really take?" because fuses don't hold watts, they allow current flow

really? you tried google?

i know....i really need to stop this crap

If a fuse that is rated 80 amps allows more than 80 amps for any extended duration, well, ya might have to use that pretty fire extinguisher.

Umm, in a sense, yes they do allow current to flow. But they also stop the current too! I think the term "Overcurrent protection device" explains what I mean.
