An improved viewing window construction for an electrical disconnect switch 10. The improved construction of the viewing window 70 permits easier installation of the viewing window 70 while at the same time reducing the complexity of the switch cover manufacturing process, eliminating the need for a window retainer 46 and increasing the resistance to the ingress of water when subjected to a stream of water under pressure.

A dual power source retrofit kit for a single power source service entrance panel. The retrofit kit is a field installable kit for retrofitting a single power source service entrance panel to a dual power source service entrance panel. The kit includes a power source selection assembly and a mounting bracket for attaching to the service entrance panel. A deadfront trim plate having a cut-out to accept the power source selection assembly is also supplied to replace the old trim plate of the service entrance panel. The power source selection assembly permits only the selected one of the primary or auxiliary power sources to provide power to the service entrance panel at any one time. The power source selection assembly is also designed such that overload protection devices/disconnect switches for both the primary power source and the auxiliary power source must be in the OFF position before switching from one power source to the other is permitted.

The present invention provides an interior assembly for an electrical distribution device having a fuse for each phase in a circuit. The interior assembly includes a plurality of modules having an operating mechanism for opening and closing a switch contact. The switch contact is connected to each fuse and phase of the circuit. Each module has a housing and means for demountably securing one of the modules to at least one adjacent module. The securing means is manually operated and integrally formed with the housing of each module. The present invention also provides a method of assembling the interior assembly of an electrical distribution device having a fuse for each phase in a circuit. The step of the method includes manually and demountably affixing a plurality of modules to one another without discrete fasteners. The plurality of modules have an operating mechanism for opening and closing a switch contact. The switch contact is connected to each fuse and phase of the circuit.

Switch having stackable fuses

The present invention provides a handle for controlling a switch mechanism of an interior assembly of an electrical distribution device having a plurality of modules. The electrical distribution device has an enclosure for housing the interior assembly. The handle includes a first piece having an elongated shape with two ends. The first end is adapted to be manually controlled by an operator and has a mating surface. The opposite end is secures the handle to the switch mechanism. A second piece has a complimentary shape for abutting the mating surface of the first piece at least near the first end. The first and second pieces are fastened without discrete fasteners.

The present invention provides a neutral base module for an interior assembly of an electrical distribution device having a plurality of modules. The neutral base module connects the electrical distribution device to a circuit having at least one phase and includes a generally rectangular body having a mounting surface. The body demountably secures to at least one adjacent module of the interior assembly with a manually operated securement which is integrally formed with the modular housing. A terminal for making an electrical connection abuts the mounting surface of the body. An electrically insulating shield having sufficient size to substantially isolate the body from the adjacent module of the interior assembly abuts the body and terminal. The terminal is releasably retained to abut the mounting surface and the shield between the body and the adjacent module.

The present invention provides a terminal and base for connecting a circuit through a fusible switch. The base has a plurality of undercut prongs upstanding therefrom and an interlock snap resiliently attached thereto. The prongs are positioned on the base to prevent movement vertically and in at least one direction horizontally. The snap is positioned on the base to prevent movement in the remaining horizontal directions. The terminal includes a generally planar body made of conductive material. The body has a plurality of edges adapted to insert into the undercut prongs. The terminal positions an opposing edge on the body opposite the plurality of edges. The opposing edge is adapted to abut one end of the interlock snap. The terminal includes a first and second means for electrically and mechanically connecting the terminal to the circuit.

Snap-fit terminal assembly

This invention provides for a tilt adjuster for a speaker support frame to adjust the tilt or position of a speaker which has been recessed mounted in a wall or the like. The tilt adjuster includes a wedge-shaped, one-piece adaptor frame body which attaches to a speaker on the front side and attaches to a speaker support frame structure on the back side. The frame structure is mounted on the wall. The tilt adjuster is preferably assembled with a speaker cover.

A wire protection device and system that can operate in combination with non-metallic and metallic enclosures to help prevent damage to branch wiring during drywall installation. In some instances, the device serves to prevent the branch wires from being dislodged from the enclosure. The wire protection device may also be made to fit into a wire clamping system that is molded integrally with non-metallic enclosure.
