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

Thank you for putting the word belief in there. Truths and facts exist for engineers and engineers alone. Well, for them and the religious, anyway.

No scientist would ever use facts, they have only theories. Go ahead, ask someone with a doctorate in any of the fields of physics, whether there are any laws and facts in science.

You will get a strong no from all of them. If you get a yes, then be assured, you are talking with an extreme minority. If you talk with a university professor in the realm of physics, you will also find out that they don’t teach facts or laws, they teach theory, and theory alone. For all the right reasons. When talking to the average person they might go for facts and laws, but when dealing with the new or exploring the new, everything reverts to the theory aspect.

When you start to play with the edges of proof and conceptual aspects, like with this subject of fuses and whatnot, things get complex and facts and laws have a long history of getting in the way (when we play in the rarefied reaches of the known). Thus, they revert to theory, which is what they really are.

I’m trying to make it abundantly clear that only theories exist, and there are no facts and laws. And that -- is the underlying force behind reason and exploration in science. It is absolutely critical that exploration go forward under such a mindset, a mindset that is not kneecapped by facts and laws before it even takes a step. All of science in it’s exploration agrees with this, even if you rarely hear them say it.
Teo, why pick me to become unhinged on? I don’t get it. If you want to get into some weird pseudo philosophical argument with me you’re barking up the wrong tree. Fortunately the world is not as complex, unfathomable, opaque, impenetrable, mysterious, theoretical or uncertain as you portray it to be.

why pick me to become unhinged on?

I believe because it’s oh so easy to do.
Can you give some other technical forums you visit so we can see what they think of you there also?

All you have to do is mention the word unhinged and George magically shows up. It's uncanny.
