Interestingly, based on the code wording, the wire from the panel to the disco is a feeder ad from the dico to the a/c is a branch circuit. Now, make the disco a nofused disco (no OCPR) and the entire circuit is a branch circuit. Webbranch circuits and feeders that serve less than 100 percent of the total dwelling unit load. Feeder circuits that serve 100 per-cent of the dwelling unit load shall be sized in accordance with the procedures in Chapter 35. E3601.2 Branch-circuit and feeder ampacity. Branch-cir-cuit and feeder conductors shall have ampacities not less than WebTypically, the branch circuit overcurrent protective device (BOPD) will be either a listed molded-case circuit breaker or fuse. Supplementary protectors, such as Eaton FAZ, can therefore be added to any of these branch circuits to “supplement” the branch circuit protection.
