The switch-closing member includes a switch-closing energy-storage rod, a switch-closing energy-storage ring, a switch-closing spring, a switch-closing positioning pin, a switch-closing release ring, and an inner sleeve pipe. The switch-opening member includes a small shaft, a switch-opening spring, a stopping block, a switch-opening energy-storage shaft, a connection rod, a switch-opening energy-storage pressing head, a switch-opening positioning pin, and a switch-opening release ring.

A load break tool for opening a high load electrical switch having a first switch contact and a second switch contact. The load break tool includes a main body extending along a longitudinal axis between a first end and a second end. The main body is movable between an extended configuration and a retracted configuration. A first contact is coupled to the first end and configured to selectively couple with the first switch contact. A second contact is coupled to the second end and configured to selectively couple with the second switch contact. In the retracted configuration the first contact is in electrical communication with the second contact. A spring assembly is mounted in the main body for biasing the main body to the retracted configuration, the spring assembly including a compression spring.

A utility probe is disclosed. The utility probed includes a body having an upper portion with first and second opposing ends and a lower portion extending from the upper portion; a shaft extending outwardly from the first end of the upper portion, the shaft including a plurality of holes therein; and an array of resilient fingers extending from the shaft, wherein each of the plurality of holes is configured to receive a respective one of the array of resilient fingers therein.

A load break cutout refuser includes an actuator configured to couple to a fuse cutout. A receiver is communicatively coupled to the actuator. The receiver is configured to receive a signal from a transmitter remote from the receiver. The actuator is configured to close the fuse cutout in response to the signal received by the receiver. A system includes the refuser and a transmitter remote from the fuse cutout, receiver, and actuator to send a signal to the receiver to cause the actuator to close the fuse cutout. A method of closing a fuse cutout using the load break cutout refuser system is also disclosed.

A load break tool includes a main body extending along a longitudinal axis between a first end and a second end. The main body is movable between an extended configuration and a retracted configuration. The main body includes an indicator housing having a window. A trigger assembly is positioned in the main body. The trigger assembly is moveable between a first position in the retracted configuration and a second position in the extended configuration. The trigger assembly includes an indicator viewable by a user through the window when the main body is in the retracted position.

An in-line power disconnect assembly for electrical power distribution systems is provided. The in-line power disconnect assembly includes a first end section, a second end section, at least one insulator positioned between the first end section and the second end section, and a switch assembly positioned between the first end section and the second end section. Each of the first and second end sections include a conductor clamp that can be rotated or twisted relative to a longitudinal axis of the first or second end section between a clamping position and an open position.
