Fuse block: What are they for?

I don't think so...no..he's just talking the regular old fuse block. with his description all clues lend toward you guys overthinking it rather than me underthinking
when's the last time anyone saw that rule in print?

if he is he is asking this then I digress but you guys have a way of only asking a quarter question at a time.

Words can be your friends.

Underthinking != not thinking. He clearly stated it and I understood it the first time.

Anyways I am also curious. If you run 10 30amp fuses is that the same as 1 300amp fuse?

in a series or parallel connections would be appropriate for electrical conversations. Glue is combined...what exactly does that mean?

All-right, all-right, my bad. I typed it real quick without enough thought.

I just hate un-combined glue ... barely works!

I gotta ask for that at like Wal-Mart sometime ... HAHAHA!

great so you've matched the abilities of the inarticulate. great minds think alike.

agu fuses :/ audiopipe ones i'm sure... it's hard enough to find the agu clips for them to make them so good luck if that's your plan.

That's a lie. They sell them by the boat load at the local radioshack...

The same ... except higher resistance!

How much higher, I do not know.

When that series of 18 fuses blows, might be kinda cool to watch!

thank god your local radioshack serves the entire nation as mine doesn't have any?

Please, continue.... //content.invisioncic.com/y282845/emoticons/boink.gif.91933e72f927f2cefc79aff02573090c.gif

well you get my point, its obvious I misunderstood. so a bolded statement acting like I'm a jackass rather than clarifying is just a waste of time. what is the point in that considering an obvious concession that I may have misunderstood your discription? so yeah. good talk.

You're right again, I bolded too quick without thinking ... Sorry 'bout that.

Unless I am just off today the resistance would be lower, resistance in parallyl is lower.

I believe the small wires in the many separate fuses would be equal to say stranded wire of the same size and number of wires.

So, I guess until someone points out something else, I disagree with the notion that many fuses have a higher resistance.

Anybody?

 

[aworldcollision 10+ year member]

If they are high quality fuses and high quality wires, the resistence should be mnimal and is not componded with the same impedence theoris you are uing.

All I can think is that 60 amp fuses can be cheater fuses to hide dangerous electrical faults. Would not a 10 amp fuse, still pop at 30 amps, regardless of how many of them pop? So, perhaps, its to comply with the 60 amp fuse rule yet still protect for massive voltage.

I base this off of absolutly nothing Just a theory. I dunno my DC nearly well enough and its what my amps are in the most need of at the moment, hence my fuse block entry. I'm upgrading my alternator and terminals and blah blah soon. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

These extreme multiple fuseblocks are no longer allowed in MECA competitions due to the fact that you could pass way more than the rated current thru the assemblies.

for example, 20 5 amp fuses would logically yield 100 amps of fusing. However, you could pass almost 3 times that much current thru that using some AGU fuse brands. The point of it all was a deliberate attempt to circumvent the rules in order to get a higher burp score on the Termlab meter.

As of this year's new rules, you can only have so many fuses in each specific class. For example, I compete in MX2 (Modified Extreme 2) and am allowed only 3 fuses.

Some of this doesn't seem to add up.

Fuses are simply to protect against heat, of course damage from heat. For example, if your power supply wire gets too hot (maybe it's too small), instead of your wire melting or catching on fire, the fuse blows.

So, I'm not clear on why the number of fuses matters ...

... Because, to also answer aworldcollision's question "Would not a 10 amp fuse, still pop at 30 amps, regardless of how many of them pop?" ... No: If you apply 11 amps to a 10A fuse, it will blow (assuming it works properly); But if you apply 11 amps to two 10A fuses connected in parallel, which are equal to one 20A fuse, they should not blow. The two 10A fuses can withstand more heat (since half the total heat runs through each fuse of the two fuses), so they wouldn't blow.

I don't see how a scenario where "you could pass almost 3 times that much current thru that using some AGU fuse brands." What's the deal??
