Do I need to keep the fuse holder if the distribution block is AGU fused????

[middlemaniac]

I just got a distribution block, but was told I have to keep my fuse holder(is this true).... Can I just switch the fuse holder for the distribution block since the distribution block says it is AGU fused??? What does AGU mean???
I got the info here http://tsw-inc.amazonwebstore.com/VO...B0007TC9SU.htm

AGU is just the type of fuses. And no you shouldnt remove your other fuse, why would you do that in the first place? Having fuses on both ends of the power wire is safer, especially if you have a 2nd batt.
