For pad-mounted transformers, how are fuses operated?

Explanation:
Fuses in pad-mounted transformers are operated externally. The primary fuse links are housed in a switch-fuse assembly mounted on the outside of the transformer cabinet, so a line crew can open or replace the fuses from ground level without opening the enclosure. The fuses will automatically interrupt current if a fault occurs, but the act of switching or isolating the circuit for maintenance is done from outside the unit. This external-access design is what distinguishes pad-mounted transformers.
