What size fuse do I need for a 800 watt amp?
An 80 would be the minimum you should be running. A good rule of thumb to start with is 10 amps/100watts. Sometimes it takes a little more, but that is a good starting point. I have an 80 on my sub amp which just happens to be 800watts and it has never blown a fuse.
What happens if you drop a fuse on a battery?
Like for instance dropping a tool or other metal object across the positive and negative battery lines. Without the fuse as protection, the wiring could overheat, melt and even lead to a fire.
Where does the fuse go on a car battery?
So, fuse has no sense. Some cars have “ battery disconnect explosive charge terminal “ connected with airbag sensor. It disconnects battery if you crash car to prevent sparking an fire after incident. It can make more sense to put the fuse on the side of the battery that goes to ground. That will often (but not always) be the negative terminal.
What does the fuse on the positive battery cable do?
So, fuse has no sense. Some cars have “ battery disconnect explosive charge terminal “ connected with airbag sensor. It disconnects battery if you crash car to prevent sparking an fire after incident. ServiceTitan® is built to grow your electrical business.
What does a catastrophic fuse on a battery mean?
I’ve installed fuses or breakers on each non-grounded wire run. A little while back I even added what is called a catastrophic fuse as a final failsafe device. My system had grown to include four large six-volt batteries packing a significant amount of capacity (464 Amp Hours).

Can a 6 volt battery be connected in series?
In theory a 6 volt 3 Ah battery and a 6 volt 5 Ah battery connected in series would give a supply of 12 volts 3 Ah (the capacity of the weaker battery always restricts the circuit) and if you did so it would work and nothing would explode (to start with).
How many amps are in a series of batteries?
As in the diagram above, two 6 volt 4.5 ah batteries wired in series are capable of providing 12 volts (6 volts + 6 volts) and 4.5 amp hours. This is where most tutorials end, but what happens if you wire batteries of different voltages and amp hour capacities together? Most people simply answer by telling you “Don’t do it!” … but why not?
