fuses are NOT brick walls. A 1 amp fuse doens't pop at 1.01 amps instandtly.
You'll have to look at the time / current charts on the LITTLEFUSE website.

Also? As near as I can figure, you have 3 types of fuse.
Standard.....in MOST equipement regardles of current
Slo-Blow....Maybe the next most common, and will withstand higher current / time before fusing
And
FAST blo, used in some delicate electronics. Thsese pop as nearly instantly as they can engineer.

NEVER over curren the fuse. A POSSIBLE but not recommended exception? Gear requries a 2 amp slo-blo. I dont' know, but you MAY get away with a slightly larger, standard type-fuse.....But I have never heard of anyone actually DOING SO......You may want to write to an applications guy at one of the big fuse companies.
Too much is never enough
