I am trying to figure out which fuses to get to fuse all my power injection lines. I use this 18awg wire for my power injection runs. I have both 5v and 12v lights so I'll break it down by type: This is the 5v strip: 30 leds/meter, each strip is 3 meters long. At 7.2w/meter(1.4a) that's ~4.3amps/strip I am looking at these fuses, they are 250v 5a. I am confused about the 250v part, is that a max voltage? Would these fuses be fine for this? Next is my 12v: Strips: 3.2amps/5 meter, but on some runs I power 2 strips. I could use the same fuses about (5a) on the single strip runs and these 10a fuses on the double strip runs. Rectangle modules: .72w/module. The most I have is 30 in 1 run (21.6w) = 1.8amps. Probably would use the same 5a fuses above. Does this all check out? I've never dealt with this before. Thanks for your time and any help/input you can give.
