Size of fuse for 4/0 wire?

[Duke 10+ year member]

The wire guide says 700 amp. I can get 400, 500, 600, 675, and 750. This stuff I have says 2000 volts on the side if that matters. Its welding wire.

I hate to come off like an ***, but if you're dealing with a setup that draws 700A, shouldn't sizing a fuse be a pretty easy task?

I can get large amperage ANL fuses, and I bought some 4/0 tin plated copper ring lugs, so I'll probably just use my generic AUDIOPIPE bolt on fuse holder... unless I can find a decently priced fuse holder that would hold 4/0, or could be modified a bit to fit it.//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Well, I'm not going to be drawing 700 amps. The amp will draw 400 or more, but not sure exactly how much. I just want to get the right fuse for the wire.

Why are you looking into 4/0 gauge wire then?

What amp do you have...

I got the wire cheap. Cheaper than a run of 1/0 even. I have a MA HK4000D.

U should probably just use a 2/0 max

lol u think that amp is gonna draw 400+ amps?

its rated at 3600x 1 @2ohm at 14.4v. 3600/14.4 = 250amps max. and I doubt u'll be drawing more then 200 on regular use. Maybe 300amps cuse its probably only like 75% efficant, but either way. U wont need 400+ amps.....

U = the ****

I wanna see how you run 4/0 wire . That's gotta be hell trying to bend it . //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Its actually very flexible and there aren't going to be any tight turns. I already have the wire which is why I will be using it.

Well, according to scottiej it will. I bought it from him.

so if i sold u a capacitor and told u it generated power u would belive me?

I doubt MA made it 100% efficient, which is what your equation is saying //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
