In discussing troubleshooting on another post I made, I mentioned using a number of circuit breakers I had on hand, then got a couple of PMs asking about them, so....
Ever burn through a 5-pack of fuses all too quickly while chasing down a trouble spot? Ever burn your last one after the local stores are closed? Ever go to the store only to discover the size you need is apparently the one oddball they do not carry or is out of stock (of course!)? Ever suffer the first-world anguish of a game down for days while you wait for "just a fuse" to be shipped?
Yeah, it sucks. And this, incidentally, is how games get overfused with whatever is on hand, which is even worse!
So stop it because circuit breakers are amazing! For just a buck or two more than a 5-pack of fuses you can plow through in a hurry, you can get an infinitely re-usable breaker that will keep you from literally burning that money the next time something goes wiggedy whack wrong.
Mouser has a whole range of them:
Simply search for the amperage you need, and choose a push-to-reset model. Here are the common sizes I have found handy:
There are lots of other sizes available....
To use them you need to save your blown fuses. Solder the breaker lugs to a bad fuse. The simply insert the fuse breaker as required, and troubleshoot away. (I will post a photo of mine later on).
The first time you reset one three times, it will have paid for itself in spared fuses, saved time and fuel, convenience, and peace of mind. The assortment of breakers I listed above cost me maybe $40 and has been one of the most valuable bits of kit in my toolbox.
