I was reading my code book and caught the section on over-current protection for A/C units. The interpretation I got is that if a unit calls for a "Max. Fuse Size" that this indicates the unit is only UL approved for fuses and that fuses must be inserted in that feed somewhere. They go on to discuss the nomenclature for units approved for both fuses and breakers. ( Can't remember the section where I found it )
I am going to be installing the wiring for a couple of mini-split A/C systems and the specs call for the "Max. Fuse Size" or 15 Amps. The A/C guy looked at me like I was crazy and told me other electricians he's worked with say they have not used fuses in years. So what's up with this? Is it something new, or something old that nobody enforces any longer?
Thank for any input.
