Abstract: An electrical watthour meter socket includes a first sub-enclosure receiving high voltage components and a second sub-enclosure receiving lower voltage components. The first and second sub-enclosures are electrically isolated from each other access control components to allow independent access to lower voltage components in the second sub-enclosure without the use of personal protective equipment required for exposure to components carrying high voltage.

Abstract: A primary enclosure for electric power meters includes at least one shelf for supporting an instrument transformer. Slide mounts are mounted to the interior of the enclosure and to the shelf for slidably supporting the shelf for movement between a first use position in which the shelf and the transformer carried by the shelf are contained entirely within the interior of the enclosure and a second extended position wherein the shelf extends at least partially through an opening in a wall of the enclosure for servicing of the transformer The shelf can include shelf brackets attachable to the slide mounts and a transformer adapter plate to which the transformer is mounted prior to attaching the adapter plate to the adapter shelf to the shelf brackets.

Abstract: A modular meter socket is releasably mountable in a housing. Support clips are disposed in the housing by fixing a mounting plate carrying the clips in the enclosure. A mounting panel fixedly carries the meter socket and is attached to the clips without the use of tools operative fasteners or additional fasteners. Alternately, a meter socket and a bypass device are unitarily mounted on a mounting panel for attachment to the clips in the housing. The meter socket and the bypass device may be mounted on separate panels, each attached to the clips in the housing without additional fasteners.

Abstract: A test switch apparatus for an electrical device includes identical modules each carrying at least one switch thereon and terminals coupled to the switch and receiving electrical conductors. Complimentary interconnecting members are formed on each base and opposed barrier walls of each module for releasably interconnecting two modules in a side-by-side arrangement. Lock elements are optionally formed on each module for locking two adjacent switch modules together, preferably after the two modules are substantially joined by the interconnected members. End pieces are interconnected by interconnecting members to endmost modules. A cover is releaseably attachable to the end pieces.

Abstract: The portable live line tool tester of the present invention allows high voltage to be applied to discrete segments of a live-line tool. If the tool has become conductive due to damage or contamination, a leakage meter will detect the flow of current. The tool can then be tested in increments to locate the damaged section. The invention further includes electrical safely interlock circuitry so that the tester is rendered inoperable unless it is correctly rigged and safety shielding is in place. The tester can be folded into an easily portable unit, making it unnecessary to ship tools to a laboratory for testing.

Abstract: This invention relates to a safety cover assembly for a meter socket having a plurality of electrically-energizable contacts adapted to receive the rearwardly-projecting contact blades or terminals of various types of electrical meters including those used for measuring both commerical and residential power consumption. The socket normally has a substantial number of electrical contact elements in suitable spaced-apart alignment to receive the projecting contact terminals of various types of meters to energize one or more electrical circuits within the meter to determine both the accuracy and efficiency of the meter. The cover assembly is preferably formed of transparent plastic insulating material having high dielectric constant including an outer apertured cover plate to provide an essentially dead front to the meter socket when energized, both when a meter is mounted in and demounted from the meter socket.
