Abstract:
A cutout is used in an electrical distribution network to electrically connect a first electric cable with a second electrical cable, The cutout includes an electrically non-conductive insulator having first and second end. A first terminal assembly is secured to the first insulator end. A second terminal assembly is secured to the second insulator end. A failsafe fuse assembly is pivotally secured to the second terminal and is movable between an engaged position and a lockout position. A reclosing mechanism is secured to the first terminal and monitors electrical current through the fuse assembly. If a fault condition exists, the reclosing mechanism opens and then closes the electrical link between the first and second electrical cable. If, after a predetermined number of closes, the fault condition still exists, the reclosing mechanism disconnects from the fuse assembly, allowing the fuse assembly to fall to the lockout position.
