Abstract: A system for isolating a power conductor includes a power conductor that extends between first and second flanking support structures. First and second collars are connected respectively to the first and second flanking support structures. The first and second collars each at least partially surround the power conductor and including respective first and second open tracks that cooperate with each other to define a sheet-receiving slot. An electrically insulating/insulative sheet is located in the sheet-receiving slot and extends continuously between the first and second collars. The sheet is secured in covering relation with the power conductor.

Abstract: An improved electrical system may be provided by electrically isolating horizontal power distribution bus bars of differing phases, disposed along a preconfigured isolated bus support molding, from one another by covering each bus bar with an electrically insulating molded assembly. The electrically insulating molded assembly has contours configured to cover a particular bus bar (with respect to another bus bar or live fastener), arranged within the constraints of the preconfigured isolated bus support molding in the electrical system (such as along the back of the isolated bus support, between the isolated bus support and a wall of the electrical system).

Abstract: An improved electrical system may be provided by electrically isolating exposed live fasteners and bus clamps in power distribution systems by attaching electrically insulating snap-based cover assemblies to the live fasteners and bus clamps. A cover assembly may include a plate element and an electrically insulating cap element. The plate element may have a plate opening and a beveled edge, and the electrically insulating cap element may have a cap edge followed by an interior recess. The cap element and the plate element may be held together by snapping the cap element over the plate element such that the beveled edge fits into the interior recess and the cap edge fits below the beveled edge. The cover assembly may be attached to a fastener or bus clamp via the plate opening.

Abstract: An improved electrical system may be provided by electrically isolating complex bus geometries by using one or more substantially flat and electrically insulating sheets. The sheet may have one or more fold lines which allow the sheet to fold in multiple directions and ways over varying configurations of power conductors. The sheet may fit within the constraints of preconfigured electrical system components without the need for redesigning such components. The sheet may have a dielectric strength per mil effective to isolate power conductors based on maximum charge and proximity of the power conductors.

Abstract: The invention relates to a reciprocating saw that includes a reciprocatable spindle for supporting a saw blade for reciprocating sawing movement. A body houses a motor and a drive mechanism driven by the motor. The drive mechanism selectively drives the spindle and the body supports the spindle. A grip extends outwardly from the body adjacent a center of gravity of the saw so as to allow an operator to operate the reciprocating saw with a first hand and support a workpiece being cut with a second hand.

Abstract: A power-generating apparatus includes a frame, an engine supported by the frame, an alternator coupled to the engine and operable to convert mechanical energy from the engine into electrical energy, and a battery charger supported by the frame and electrically coupled to the alternator. The battery charger is operable to charge a battery pack with the electrical energy from the alternator.

Abstract: A battery pack for powering a cordless power tool. The battery pack includes at least one battery cell operable to supply a discharge current, a switch operable to control the discharge current and a protection device to protect the switch. The protection device is positioned such that the device absorbs a current traveling in a direction opposite to that of the discharge current supplied from the battery cell.
