If there are two feeds, I would use two smaller fuses instead of one bigger one. Then you reduce the chance of drawing too much current through one smaller feed wire and not blowing the fuse because it’s sized to handle the current for both feed wires and all 8 switch circuits.
It’s also a little more granular, where if you blow one fuse then the other four switch circuits continue to work. Since this appears to be a panel of circuit breakers, I would assume each circuit itself is protected by tripping it’s own breaker.

Thanks @TailLights. I do like the point about the granularity. Correct, each circuit is protected by its own breaker. I dug up some photos of various installations and it looks like it's common to place a positive bus right beside the switch panel and then run the short feeds from the panel directly to the bus with no fuse - presumably the main feed to the bus is on a breaker in that case...
