Hook Stick is first attached to a universal pole at least six feet long. It is then positioned across the front of the Type FSC Cutout, with the Hook Stick anchor hung on the attachment hook on the far side of the cutout. The pull ring of the fuse tube or disconnect blade is engaged with Hook Stick's pull-ring hook and held fast with Hook Stick's pull-ring of the fuse tube or disconnect blade is engaged with Hook Stick's pull-ring hook and held fast Hook Stick's pull-ring lacth. As the universal pole is pulled downward with a firm, steady stroke, and as Hook Stick is extended to its maximum length, the cutout is opened and the current si diverted through Hook Stick - at the same time Hook Stick's opening stroke, its internal trigger trips, the charged operating spring is released, the internal contact are separated,and the circuit is positively interrupted. The only sound is that of Hook Stick tripping.
Circuit interrupting is independent of the speed at which the Hook Stick tool is operated. All that is required is a smooth operating stroke without hesitation, wihtout jerking, until released to reset Hook Stick for its next operation.
And resetting Hook Stick is easy too merely release the resetting latch and firmly close the extended tool to its fully telescoped position,it's that simple.For detailed information on Hook Stick, FRT'S portable load break tppl, see FRT Descriptive Bulletin 811-30.
Reach across the front of the cutout and attach Hook Stick's anchor to the attachment hook on the far side of the cutout and then engage its pull ring with Hook Stick's pull-ring hook.
Hook Stick's pull-ring latch prevents disengagement of the cutout pull ring and Hook Stick's pulling hook.
A firm, steady downward pull on Hook Stick's - to its maximum extended length-opens the cutout in the normal manner as the current is diverted through Hook Stick. At a prederermined point in the opening stroke, Hook Stick trips, beraking the circuit positively.
Hook Stick is disengaged by first removing its anchor from the cutout attachment hook. Then, with the blade in the open position,Hook Stick is removed from the pulling with a simple "roll-off" motion.
