A maintenance-free electrical bus assembly is provided for a switchgear cabinet. The maintenance-free electrical bus assembly is coupled to a switchgear device in the cabinet, and includes electrical bus members, at least one bus joint comprising an electrical connection of two or more electrical bus members, and a fastener assembly fastening the bus joint and maintaining the electrical connection between the electrical bus members thereof. The fastener assembly includes at least one first fastening element having a plurality of first threads, and at least one second fastening element having a plurality of second threads. The second threads threadably engage the first threads of a corresponding first fastening element, in order to perpetually secure the first threads and the corresponding first fastening element, and to resist undesirable loosening of the bus joint once the fastener assembly has been fastened. Thus, inaccessible bus joints within the cabinet do not need to be inspected.

A circuit interruption apparatus for a power circuit having a power source and a load includes a termination mechanism for interconnection with the power source and the load; a circuit interrupter having a line terminal and a load terminal for interrupting the power circuit between the power source and the load; and a pivot mechanism for pivoting the circuit interrupter between a first position wherein the line terminal and the load terminal are interconnected with the termination mechanism, and a second position wherein one of the line terminal and the load terminal is disconnected from the termination mechanism. Alternatively, a circuit interruption apparatus for the power circuit may include a line termination mechanism for interconnection with the power source; a circuit interrupter having a line terminal and a load termination mechanism for interconnection with the load; and a pivot mechanism for pivoting the circuit interrupter between the first position and the second position. Alternatively, a circuit interruption apparatus for a power circuit may include a circuit interrupter having a trip lever mechanism for tripping open the power circuit and for interrupting the power circuit between the power source and the load; and a fuse in series with the circuit interrupter between the power source and the load for interrupting the power circuit therebetween and having a striker pin for engaging the trip lever mechanism and tripping open the power circuit whenever the fuse interrupts the power circuit.

An energy storage and release control mechanism is provided for a stored energy assembly of an electrical switching apparatus. The stored energy assembly includes a shaft, a stored energy mechanism, and a charging mechanism, such as a charging cam. The charging cam is movable to pivot upon the shaft, thereby charging the stored energy mechanism. The energy storage and release control mechanism includes a ratchet coupled to the charging cam and including a plurality of teeth, a mounting assembly, and a plurality of pawl assemblies. Each pawl assembly includes a pawl pivoting between an engaged position corresponding to the pawl engaging the teeth of the ratchet to resist inappropriate movement of the charging handle, and a disengaged position corresponding to the pawl not engaging the teeth of the ratchet. Preferably, first and second pawl assemblies include first and second pawls, respectively, wherein only one of the first and second pawls engages the teeth of the ratchet at a time.

A shutter assembly is provided for an electrical system including at least one electrical switching apparatus, such as a circuit breaker, and a plurality of electrical bus members, and a plurality of electrical cable members, and a ground member with a plurality of contacts. Each of the conductors of the circuit breaker is removably coupled to a corresponding primary contact to electrically connect the circuit breaker to the electrical bus members and to electrically connect the circuit breaker to the electrical cable members and to electrically connect the circuit breaker to the ground members. The shutter assembly includes a flexible insulating member movably disposed between the conductors and the primary contacts. The flexible insulating member moves between a first position in which it provides access for the conductors to be coupled to the primary contacts, and a second position in which the flexible insulating member isolates and electrically insulates the bus member conductors from the primary contacts and the cable member conductors (“disconnected”) or isolates and electrically insulates the cable member conductors from the primary contacts and the ground member (“withdrawn”). An electrical switching apparatus and an electrical system employing the shutter assembly are also disclosed.

A dampening apparatus has a housing with a plurality of first guide members and a plurality of second guide members coupled together. A first biasing member is located in an area proximate to the first guide members and within the housing. A first planar member is provided having a plurality of first apertures with the first guide members or the second guide members passing through the first apertures. A plurality of second planar members is provided having a plurality of second apertures with the second guide members passing through the second apertures. A plurality of second biasing members is located in an area proximate to the second guide members. An elongated shaft is coupled to the first planar member. The dampening apparatus could be included in a circuit interrupter.

A drawout switchgear apparatus is characterized by a cell having a front opening through which a circuit breaker is movable on tracks into and out of the cell for engagement and disengagement with electrical terminals within the cell. A cell frame includes formed columns at outside corners members, cross-strut members, and formed horizontal members which members are of similar cross-section of a substantially U-shape with U-legs and a bight and with a laterally extending flange. Each member converges to form junction corners where they are fastened together. A track extension and interlock cooperate to facilitate removal and retention of the unit into and out of the cell.
