This might be an easy question but I can't seem to find an answer.

I added an aux fuse box and currently have running board lights in one slot and bed lights in another. They each have a separate relay and fuse. I'm planning on adding interior lights that will also have it's own relay.

My question is should they each have an individual fuse the way I have it wired now or can they all be attached to the same slot with only fuse for all 3? Each slot in the fuse box is rated up to 30 amps and the combination of all 3 will be about 5 amps. I was thinking of using a 7.5 amp fuse if I put them in the same slot.

Direct to Constant wires should be fused individually. You can share a fuse for powering relays only as the only draw 250ma each.
