Abstract: A mechanism for removably mounting instruments with a cylindrical outer case to a flat panel over an opening with a peripheral wall extending perpendicularly from the rear side of the panel and two or more gripping assemblies mounted adjacent to the wall. Outwardly extending flange members mounted on the outer case at one end of the instrument are cooperatively and removably engaged within the gripping assemblies. The gripping assemblies in an alternate embodiment are removably mounted through slots in the panel. A user can mount and unmount the instruments from the rear without requiring the use of any tools.

Abstract: A watthour meter socket adapter electrically connects an external sealing ring and/or a metal cover ring on a watthour meter to ground. A surge ground conductor is mounted on an end mounting flange of the socket adapter housing and extends within and is joined to the housing by a first metal fastener. One end of the first metal fastener extends exteriorly of the housing and supports a first metal tab which is engaged by the metal sealing ring. A second metal fastener extends through the surge ground conductor and supports a second external tab engagable with a grounded meter socket cover. Alternately, a tab extends integrally from an upper end of the surge ground conductor for engagement with the sealing ring. In another embodiment, an annular surge ground conductor is mounted within an annular sidewall of a watthour meter socket adapter housing.

Abstract: A panelboard apparatus includes an enclosure; a first plurality of circuit breakers including a remotely controllable solenoid for actuating the circuit breaker and switching a circuit from a power line through a load; a holder for holding in the enclosure up to a second plurality of circuit breakers including the first plurality of circuit breakers; a controller for controlling up to the second plurality of circuit breakers; a printed circuit connection mechanism for connecting up to the second plurality of circuit breakers to the controller in one of a plurality of configurations, including printed circuit boards having a plurality of interfaces for up to the second plurality of circuit breakers; and a switch selection circuit for selecting one of the configurations in order to determine a location in the enclosure of a first one of the second plurality of circuit breakers.

Abstract: A front removable gauge assembly including a case gauge housing for locking the assembly to an instrument panel. A printed circuit board is mounted within the case gauge housing in electrical contact with conductors of a connector shell which extends from the case gauge housing for electrically connecting elements on the printed circuit board to an instrument signal source. A front removable gauge unit is removably mounted within the case gauge housing and contains an instrument assembly which can be mounted for 90-degree or 255-degree pointer sweep. From the bottom of the front removable gauge unit, a connector stud and wiper contacts extend. The connector stud has a protruding key which engages the bottom surface of the printed circuit board upon clockwise rotation of the front removable gauge unit to thereby removably lock it to the printed circuit boards.

Abstract: An instrument panel with meters/indicating lamps and their drive circuits implemented therein, a centralized control circuit board provided with control circuits for vehicle-mounted electric equipment including the meters/indicating lamps, and an electric junction box for distributing power sources and input/output signals for the vehicle-mounted electric equipment and for integrating ground wires, are gathered and integrally united. Electric wiring and installation of electric instruments such as an instrument panel in the dashboard portion of an automobile are facilitated.

Abstract: An apparatus is provided for enclosing and protecting an electric meter for storage or transport purposes. The apparatus is comprised of a base unit and a cover unit of rigid plastic that provide both shock and thermal protection to the meter. An inwardly extending ring on both the base and cover encloses the meter's flange, thus centering and immobilizing the meter in the case. Both the cover and base unit also have protruding lips of slightly different sizes so that the cover lip accepts the base lip within it. In addition, each lip is threaded, so as to attachably engage with the other and, when rotated, lock the cover, the base and the meter together.

Abstract: A preconstruction utility meter pedestal for the purpose of providing underground electrical and communication service to a building construction site after a foundation has been constructed but before a building has been erected upon the foundation. The pedestal comprises an elongated, vertical electrical service rigid steel conduit for conducting electrical service from an underground electrical service system to a utility meter box mounted on the upper end of the conduit and having an electric meter mounted therein. The rigid steel conduit is adapted to be fastened by an upper and a lower mounting plate, respectively, to the front face of the foundation. A communication cable plastic conduit, and a temporary electrical power box are carried by the electrical service rigid steel conduit. The electrical service rigid steel conduit supports a telephone interface box mounting bracket for the reception of an interface telephone box.

Abstract: A modular power source monitoring and control system is mounted within a common power panel enclosure and includes a main lug assembly and a metering, relaying and control assembly. The main lug assembly includes a mounting and power connecting arrangement and a connector lug arrangement. The metering, relaying and control assembly includes a mounting and power connecting means and an electrical circuit for metering and controlling a power source. For both assemblies, the mounting and power connecting arrangement is in the form of a base member having a pair of mounting brackets on either side and conductor stabs extending from the bottom.

Abstract: A watthour meter socket adapter includes at least one additional jaw terminal for receiving one blade terminal of a plurality of blade terminals of a watthour meter, which blade terminals are provided in a greater number than the available jaw terminals in a watthour meter socket which normally receive the line and load blade terminals of the watthour meter. The additional blade terminal extends through and outward from the watthour meter socket adapter housing. An electrical connector is mounted on the additional blade terminal externally of the watthour meter socket adapter housing for electrically receiving an electrical conductor in the socket adapter not normally connected to the line and load jaw and blade terminals in the socket adapter. A jumper is disposed within the watthour meter socket adapter housing and extends between selected additional jaw and blade terminals in the watthour meter socket adapter.

Abstract: An improved electrical service pedestal is provided, which has a lower portion and an upper portion, the latter of which features a pivotally mounted first section to permit easy access to a meter disposed there within. A second section disposed forward of the front of the first section is independently openable to permit a clear viewing of a meter disposed within the apparatus. The lower portion includes an openable front door, spaced from an openable interior door as well as a stepped and swept or other raceway for the wiring from the utility to the user's meter. Access to the raceway is gained through a removable side door.

Abstract: A base for an electric utility watt-hour meter made from a polycarbonate material preferably reinforced with glass fiber and ultraviolet light stabilized. The molded base receives current terminals that have outwardly directed lugs engaging one face of the base and there are locking arms on the other side of the base resiliently biased against the lug to engage a locking formation thereon. The base has a knife-edge rib extending about its periphery to sealingly engage a front edge face of a cup shaped transparent cover for the meter. A metal ring joins the cover to the base the metal ring being a band with a first series of lugs struck out and directed inwardly to engage the flange on the cover and a second group of tabs struck outwardly and bent inwardly to engage the bayonet ramp surfaces on the base.
