distribution blocks

could someone give me a 101 on them (fuse ones/none fuse ones?)

what do u want to use them for? if u have an application share it. if not come up with a hypothetical situation so that u understand it better.Quad L Handyman services

ahh, sorry. i'm actually checking out a few amp install kits, and there are some decent bargains on ebay, but some of the kits do not include the distribution block. i'm planning on running a 4 gauge into a dis. block and 2 8 gauges out. will use one for a sub later. and i noticed some of those distribution blocks have fuses, and some don't.

as long as the 8 guage is short enough to carry the current of the fuse next to the battery is rated for you do not need a fused distribution block. go to this page on this site to determine it. https://www.the12volt.com/info/recwirsz.aspPioneer PEH-9660mp

yea, i'm not planning on going over 600, more like around 400, or even 250's...looking at some mtx's.

you should be fine without a fused one thenPioneer PEH-9660mp

thank you.

My dist blocks came with places to install fuses, so I will do it just for extra safety I guess.  I got the blocks as part of one of those Ebay deals.  I figured since it was a good deal then I should go with overkill on the wiring instead of using wire that could not properly transfer the power.  And if I upgrade my gear in the future, I'll already have wiring that can handle it.  I paid about $150 for 3 dist. blocks, tons of remote wire, and tons of 2 gauge power and ground wire.  Now I just need to pick up an inline fuse and battery clamp for under the hood and some 4 or 8 gauge wire to run from the dist. block to the amps. Plan, Research, Do

The ones with fuses are power distribution, and the ones without fuses are GROUND ditstribution. Do not try to interchange them. You should never fuse a ground wire. If the fuse in the ground wire should happen to blow, the amplifier instantly looks for a new ground path, and if the chassis of the amp is not connected electrically to the chassis of the car, usually the ground becomes the shield of the RCA, which will likely cause INSTATANEOUS damage to the deck - not the RCAs. This being said, buy the 4 gauge kit (even though you may never need that current capability) use a fused distro block for the power, and use a NOT fused distro for the ground. Just make certain all of you cables are equal and opposite... i.e. if you have a number 4 from the battery to the block, use a number 4 from the ground block to the chassis. Likewise if you are running a number 8 to the amp from the fused block, run a number 8 to the ground block.It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
