4/0 fuse holder

[vickman08 10+ year member]

im so frustrated that i cant find anything that fits 4/0 welding wire...what are u guys that have 4/0 doing for fuse holder?the highest reducer i have seen is 3/0 to 0....but even then would that defeat the purpose of having a big power wire? NEED HELP bad as this is the only barrier that i cant get around...all the pieces to my system are in place....just this bullshiiit assss problem

I wold recommend making your own. ANL is an easy holder to make, though the thought of it being made by someone give you a feeling of assurance? xD There are ANL dimension datasheets on the internet. Do some googling and have some fun. The next choice is: Plated copper, or aluminum. xD

appreciate that do you have a link?

you can use this:

and just modify the plastic, by cutting a bigger opening...

thats what i would do...

better yet make your own out of copper

That's what I design mine off of.

Heres the one I use for my 4/0 with 500 amp fuses.

thx man, so nothing bad could come of trimming the plastic?

You can use a reducer it wont defeat the purpose. Due to the fact that a reducer is solid and can transfer much much more current that wire or rather wire strands.

If you don't believe me look at an anl fuse how do think it transfers all that current thats coming through a big *** cable that connects to your fuse holder through that little bridge of material connecting both sides of the fuse. ( Solid ) is the key word. Trust me!!!

Voltage drop is the key concept of the whole idea.

You wont loose voltage either though. Current and voltage are hand in hand.

I had to make my own distro block for 2/0

Just bought a piece of aluminum and drilled/tapped it

I'll see if i can find a pic, any local machine shop should be able to help you out for about an hours worth of labour if you cant do it yourself.

Not always the case. Voltage drop determines dissipation based on current. xD Have you had experience with this outside of car audio LVHC systems? //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif

Well, if you're saying resistance limits voltage and current at the same time, look into something called a resistive ballast. Another thing to say so, that if you limit current, you limit voltage, look into something called an inductive ballast.

xD I'm just trolling about your statement, not the application of the fuse. The fuse is not a form of resistive limiting. It starts to melt when current density is too high.

Yah I know a lil about that, but im just saying a reducer that is pobably no more than an inch long and made of a solid material, more than likely solid brass with platinum plating or gold plating, will carry in upwards of 600 amps or more especially one that is a 3/0 to 1/0. Thats big. You will get very very little resistance out of that. Maybe a half of a mV at that. That's nothing to worry about in a 12 volt system.
