For protecting wildlife from high voltage conductors proximate to a utility pole, dielectric covers are used to cover fuse cutouts, bushings, solid-blade disconnects, lightning arrestors, or other connections to insulators. Such covers include a vertical slot for receiving an energized wire so the cover can be installed using a hot-stick while the wire is energized. The vertical slot substantially faces the utility pole. To prevent squirrels storing nuts in the cover via the vertical slot, a squirrel guard is fitted over the top of the cover to block access to the vertical slot in the cover. The guard has a second vertical slot for receiving the wire so can be installed while the wire is energized. The guard may be customized for the particular cover used with it. Retaining pins secure the guard and cover in place.

A switch mounting device comprises: a resin seat having an upper surface and a lower surface; a switch mounted on the upper surface of the seat; and terminal members fixed to the lower surface. The seat has claw parts on the lower surface thereof. The switch has a main body part, which is operated by pressing in the X direction, and connection terminals extending downward from this main body part. With connection terminals led out to the lower surface of the seat, the connection terminals are electrically connected to the terminal members. The terminal members are fixed to the seat by the claw parts by way of being slid along the lower surface of the seat.

Solid state and hybrid circuit protection devices include improved chemical, static discharge and impact resistant housing construction, arc-free switching operation, secure terminal assemblies and thermal management features. The solid state and hybrid circuit protection devices are ignition protected and avoid possible explosions and therefore obviate a need for conventional explosion-proof enclosures to ensure safe operation of an electrical power system in a potentially explosive environment.

A guard member is for an electrical switching apparatus of an electrical system. The electrical system includes at least one electrical conductor. The electrical switching apparatus is structured to move from a CLOSED position to an OPEN position in response to a trip condition. The electrical switching apparatus has a terminal end coupled to the electrical conductor. The guard member includes a body having a receiving portion structured to receive the electrical conductor, and a coupling portion extending from the receiving portion and being structured to be coupled to the terminal end. The coupling portion has a number of thru holes in order to dissipate heat generated by the electrical switching apparatus moving from the CLOSED position to the OPEN position.

Modular circuit protection devices and configurable panelboard systems include arc-free operation, thermal management features providing safe operation in hazardous environments at lower cost and without requiring conventional explosion-proof enclosures and without entailing series connected separately provided packages such as circuit breaker devices and starter motor contactors and controls.

A switch assembly includes a body including a plurality of pressable switches, and a controller configured to control a connected device according to inputs received from the plurality of pressable switches, wherein the body further includes a pin extending from a surface thereof; a switch cover including a recess formed in an interior surface for receiving the pin such that is pivotable about the pin, wherein the plurality of pressable switches are each disposed to be pressable by pivoting the switch cover about the pin.

A building device with a front accessible address programming interface is provided. The building device includes a mounting base having front and rear surfaces. The front surface defines two connector channels extending towards the rear surface. The connector channels are spaced apart and sized to each receive a respective prong of a programming device connector plug. The building device further includes external terminals disposed on the rear surface, internal terminals, a group of normally closed switches having a common control input, and an actuator. Each switch connects an external terminal to a respective internal terminal when the common control input is deactivated to provide a network connection. The actuator is connected to the common control input and disposed such that the connector plug engages the actuator to activate the common control input of the switches when each of the connector channels receive a respective prong of the connector plug.

An electrical device such as, for example, a battery-powered electrical switch is disclosed. The battery-powered wireless switch includes one or more mechanisms arranged and configured to provide simplified access for servicing (e.g., replacing) the batteries located within the wireless switch. In one embodiment, the wireless switch is arranged and configured so that the batteries may be accessed by reconfiguring the wireless switch from a first closed position to a second opened position to access the batteries. Thus arranged, removal of the wireless switch from a wall-box or a surface of a wall is not required, the user may only need to remove the wall-plate in order to reconfigure the wireless switch. In one embodiment, at least a portion of the wireless switch is pivoted from the first position to the second position to provide access to the batteries.

A housing includes a first wall and a second wall. The first wall and the second wall face each other in a first direction. A printed circuit board is accommodated in the housing with one surface of a substrate facing the first wall. The housing has a through hole. The through hole extends from an outer surface through an inner surface of the housing. The through hole is open in the inner surface of the housing along a second direction. The second direction is orthogonal to the first direction.
