Maxi fuse

[ronald s]

Could a 60 amp maxi fuse be used to protect 80 pound thrust minn-kota terrova trolling motor wiring rather than a marine grade 60 amp breaker.Any pros or cons to either one other than having to carry extra fuses.

It could. No real cons to a fuse, except like you noted, that you should carry extras.

I recently changed over to the ATU blade fuses simply because their easy to find.

If you haven't seen one of those or their holder in person you may be shocked by how much bigger they are than the standard blade fuses.

Re: Maxi fuse

fuses are diffrent than breakers.
a fuse is nothing more than a wire that is designed to heat up at a certain ampage until it fails. they are designated as instant, time delayed and current limiting amoung other things
a breaker is either thermal or magnetic or both. they work by either winding a wire around a pin to make a magnet that will unlatch the breaker or they have a wire that will heat a soldered connection or metal strip to unlatch the breaker.

a trolling motor may cause a surge when starting that will overload a fuse for point something of a second that may cause the fuse to blow unless it is a time delayed fuse. a breaker generally is slower to respond so it rides out this surge better.

will it matter on your boat....proberly not but i would surgest the largest fuse the trolling motor and wiring on the boat allows.

Thanks for all the replies. Gives me a second option to think about. Cheaper to.

No doubt about it - a manual reset breaker is the way to go.
