Much appreciated AVGeek. ::008::AVGeek said:For the PC-8 feed itself, I'd say stick with the 30a fuse. That way you haven't limited the capacity of the fuse block itself.
If you really want to see what your full draw is, the formula is the same. Just add up the wattage of all the accessories you plan on running, then divide that number by the (nominal) 12 volts of the system.
@creggur, if you used 13.8v, your overall amperage will go down (owing to the inverse relationship between voltage and current), so if you do drop below 13.8, your fuses might be closer to the edge. Using 12v gives you some more "headroom" when calculating draw...
