On distribution systems, in areas of higher fault current, or higher system voltages, especially on heavily loaded UG laterals, construction crews would rather disconnect the load using a link break disconnect, as opposed to opening the cutout door. The question which has come up is whether this should be implemented on OH laterals as well. Using a link break disconnect is obviously more expensive. Would you have any input on your practices and the reasons why?

b. Periodic inspection of fuse links in distribution cutouts. These fuse links may require periodic inspections,
since corrosion of the lower terminal of the fuse link (generally a flexible cable) at the lower open-end of the fuse holder may cause breakage or melting at this point, rather than in the currentresponsive element. Link-break cutouts are particularly susceptible since their link-break mechanisms impose a mechanical strain on fuses.
