fuse differences??

[95Prober 10+ year member]

hi, im gonna buy a distribution block for my amps from (1) 0/1 guage to 4 guage wires. now i see there are 2 types of fuses i can choose from :

ANL fuses OR AGU

the ANL fuses are more expensive at around 5$ a piece but the AGU's are 1$ a piece. i alwasy though a fuse is a fuse, so why the big price gap ??

also in the BLOCK itself price, there is big difference in price too. now the ANL block looks of better quality and had the digital read-out so that why its higher in price i imagine, and i seen was 30$ with the L.E.D read-out

. but i can buy a cheap "gold plated" look with the cheap AGU fuses for like 15$.

i know there is a quality difference, BUT what about performance ?? especially where the fuses cost 4 x more. does that mean those fuses are harder to blow as well??

thx

Heres a nice chunk of info about power wire-

2.3 What is the best power wire to use? [JSC]

================================================

There is much debate over the benefit of certain wiring schemes

(oxygen-free, multistranded, braided, twisted, air core, you name it).

However, most people do agree that the most important factor in

selecting power wire is to use the proper size. Wire is generally

rated in size by American Wire Gauge, abbreviated AWG, or commonly just

"gauge". To determine the correct wire size for your application, you

should first determine the maximum current flow through the cable

(looking at the amplifier's fuse is a relatively simple and conservative

way to do this). Then determine the length of the cable that your will

use, and consult the following chart, taken from the IASCA handbook

(see Section 6.1),

Length of run (in feet)

Current 0-4 4-7 7-10 10-13 13-16 16-19 19-22 22-28

0-20A 14 12 12 10 10 8 8 8

20-35A 12 10 8 8 6 6 6 4

35-50A 10 8 8 6 6 4 4 4

50-65A 8 8 6 4 4 4 4 2

65-85A 6 6 4 4 2 2 2 0

85-105A 6 6 4 2 2 2 2 0

105-125A 4 4 4 2 2 0 0 0

125-150A 2 2 2 2 0 0 0 00

If aluminum wire is used instead of copper wire, the next larger size

(smaller number) should be used. You should also consider the

installation demands: will you need to run the wire around corners or

through doors or into the engine compartment? These sorts of problems

in the car audio application require some special care in cable

selection. You will want to have cable that is flexible; it should

have thick insulation as well, and not melt at low temperatures. You

don't want to install wire that is rigid and prone to cracks and cuts,

or else the results could literally be explosive.

As for which distro and fuse to use, they will all perform the same, some are just fancyier then others, the cheap stuff will work fine.

typically ANL are rated a lot higher, they can go up to 300amps and up there. I dont believe AGU go anywhere near that high.

ANL

I have had problems with AGU fuses just snapping or falling apart.

Agu = 20-80a

Afs/kf = 80-150a

Anl = 100-500a

Maxi = 10-60a

Maxi go up to 150.
