Fuse Amperage Question Help Fast

[kicker06 10+ year member]

Well my mini-anl 120amp fuse and holder melted today and I need another one, this time not the mini. I am trying to decide if I should go with 150amp or 200amp fuse for the fuse holder.

My amps are connected through the same power cable to the battery. One amp has 3 40amp fuses (120amps) and my other amp has a 40amp fuse.

So 120amps + 40amps = 160amps.

Should I go with the 200 instead of the 150, since the fuses on the amps add up to 160amps?

200amps will be fine if my amps have 160amp fuses all together, correct?

BTW I am getting knukonceptz.

fuses(on wire) are to protect the wire from catching fire. so use the biggest fuse capable for that certain gauge of wire/cable.

4 Gauge is the wire size.
