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

Which is worse -misrepresenting a fact or embellishing your potential results?

"Perceptions determine value, and sometimes misconceptions cause prices to become utterly disconnected from the true underlying worth

Doubt I'll earn another gold star for this one

Probably get a poke in the eye with a sharp stick instead

>>>>>Whoa! I'm starting to get a bad feeling.

@almarg Thanks Al. Praise from you means a lot!

@teo Sorry if I was heavy-handed. Must be getting tetchey in my old age.
In physics as in all of science we have theories and we also have Laws. Laws cannot be broken except for Newton’s Laws of Motion in the extreme relativity case - they were broken more than 100 years ago. But there are many Laws of science like Boyles Law, electrical Laws like Ohm’s Law, that are more like facts, really, not theories. Black holes are 99% fact, 1% theory. There are many "facts" in science: the speed of light, the speed of sound, Avagadro’s number, the gas constant, Universal Constant, the equivalency of mass and energy (E=mc2). You don’t have to look too far to see a lot of facts.

Yes, but it always remains that they are conditionally facts and that in reality, facts don’t exist. That facts are a human construct, an idea, like ’chair’, or numbers/math.

All existence is from a human point of view, in all analysis that ’we’ are aware of. It is entirely subjective and logic itself is a construct, like fact, law, chair, number, and so on. All inescapably relative, inescapably theoretical and of a subjective construction. Objectivity only existing in the pressured opinion and projection of the non self-aware, for the most part (some are mildly self aware). Objectivity is a child branch and construct of a subjective mind and reality. Objectivity, as far as we can tell, exists no-where else.

Same thing for local reality, and forests and trees. All of existence is subjective theory with high predictability, but inescapably theory and outside of fact, as facts don’t exist. It’s just a moniker for a relatively predictable observation by a subjective reality self- reflection.

It would be good for some to remember - or understand that for the first time. That the only fact we know, is that facts don’t exist. Paradox, like the wave particle quantum quandary. Predictable en-masse, spooky action at a distance, in the quantum underpinnings of that en-masse grouping.


Engineers are 'allowed' to have 'facts', so they can build things without resorting to the reality of theory and possibly building things that kill people. They require maximum stability and quality in their theory and it must be unchanging to allow for as perfect a predictability as is possible. That kind of mindset that desires facts and perfect things, tends to be drawn to the field of engineering.

However....no trained scientist worth a damn ever uses or deals with facts. But they will if they have to deal with the public, who live in the 'factual' world, or the world of emotionalized logic projections.
saying "in reality, facts don’t exist" tells a lot about your products
