Fuses fuses fuses


Ok, this is about fuses

1- a standard Bussman fuse is UL approved. Are any "high end" fuses UL approved?

2- do any component manufacturers supply their gear with any of the usual suspects of high end fuses as opposed to a standard Bussman?

3- let's say fuses do make a difference. Given incoming power is AC, why could fuses be directional? 

Not meaning to light any fires here- 

thanks in advance

That's one of the primary functions of those silver type contact enhancers to fill in any micro gaps and establish a better more uniform contact surface between Mr. fuse and the fuse holder. I also suspect the silver plated fuse holder might have a smoother surface than a generic fuse holder but not completely sure about that. Better safe than sorry, just use the contact enhancer with the silver plated fuse holder. Why take chances?

Let them accuse Al, and we can both be called "flat earthers"
This "Tech Talk" forum and is for technical talk, I see nothing here that resembles this.
Maybe it should be moved to a new forum heading for things like this, called "Things we can't explain"

Well, at least "Things you and Al can't explain," anyway.


Hello Bob.

There are fuses that are made to be soldered in, they look like resistors, and don't cost much. I use them on conservatively rated power supplies for exactly this reason. You can buy them from DigiKey - search for fuses, 'through hole' under the column 'mounting type'. I think the smallest they sell is 1/16 amp, the biggest is 20 or so.

If you don't blow fuses much, it's a good solution.

But you really need to make sure they are Cryo'ed and in the right way around. goo.gl/Y3ENpJ
