They put additional fuses in Xmas tree lights now with tiny wires, they used to draw more but also had larger wires for fault, there was no fuse on them. In the case of the AC unit as was mentioned by others must read the tag and use the breaker on the label and ideally the correct wire size. What they are essentially doint is leaving it up to the installer to provide the cord and plug,,, so to speak that would be provided on a welding machine.
The reason for the breaker size correct is that the rest of the machine is designed to be connected to a current limited circuit for fault protection. This is why we simply dont hook all the 220 stuff to 100A service, could if a heavier cord was used and additional breakers. Some equipment wired that way and a service is essentially that. Lots of service entrance based on calcs/
