In larger projects where you are going to have to split a large supply into several separated runs you'll want to fuse each run independently. If you ar going to run 40A from a 60A power supply for instance, like others have suggested below it's best to run a few wires at for instance 10A.

Although it's not 100% accurate, power will take the way of the least resistance so if you lay down several wires next to your LED strip, the higher amount of copper and lower amount of resistance on those wires to the specific spots will automatically "distribute" the power among the available paths.

Always fuse below the rating of the wire (and if possible the end device), so if the wire is rated up to 15A for instance, fusing for 10A is a good idea that way, whatever happens it can never go up in smoke and cause a fire.

Since we are talking low voltage, car parts are easily available and cheap. For just a few links you could use one of these blocks: https://www.amazon.com/Support-Truck-Circuit-Standard-Holder/dp/B012CQEPN2 but if the project is a bit more complex or high amount of wires and Amps are used, these distribution blocks make your life a whole lot easier!: https://www.amazon.com/Kohree-Automotive-Waterproof-Negative-Indicator/dp/B07S99H25W Those are really excellent to work with, you can get them in 6 or 12 way variants and they take cheap car fuses which are available in lots of different values.
