 Ender fuse cut out barrel. Now what can you tell me about this one? All right, this is the wire that carries the current when it sees too much current it burns through and just melts it and drops You come in you see this thing hanging down Hanging down like this, you know, you've got a problem This wire has seen a fault and has opened up to protect the rest of the system further upstream This little wire burns through so that you don't have a transformer blow up or the conductor burns through It's just another safety measure Now if you open up, this is your fuse barrel pack bottom here You have a little rating for what size fuse it is. Can you see that one? 10 that's 10 amp fuse You have different ones. You have quick action. You have slow action advantages of the quick action is it'll go right out right away when it sees a fault Problem with that is you get more nuisance faults more things just like a branch fall in across that happen to trip it out That for transient fault that probably would have cleared itself in a second anyways But you have slower action fuses too that take more time You can throw this in hop in your truck think that you have the problem fixed about the time you start that truck up Bam you hear that cannon go off and that fuse barrel drop back down
