In utility-intertie systems, the circuit between the inverter and the ac-load center may be considered a feeder or possibly a branch circuit. Fuses used to protect dc or ac branch (load) and feeder circuits must be listed for that use. They must also be of different sizes and markings for each amperage and voltage group to prevent unintentional interchange [240 VI].
