Fuselink acts as a protective, sacrificial conductor at the entrance, so it must carry less current than the main entrance cable. That’s achieved by using a conductor gauge finer than the entrance cable. Requiring a minimum length of 2 feet ensures there is enough physical length for proper termination, heat dissipation, and safe installation, so the fuselink will open before the larger feeder if a fault occurs. Together, two gauges finer than the entrance cable and a minimum length of 2 feet meet the protective intent and installation practicality described in the standard. Options that omit the finer-gauge relationship or specify an incompatible length don’t provide the same level of protection or fit the requirement as stated.
