  • Patent number: 6520798
    Abstract: A housing carries an electrical disconnect switch having movable contacts. A cover is mounted on the housing and has an opening allowing access to a control lever of the disconnect switch. Electrical conductors are connected to the disconnect switch within the housing and have a blade terminal portion extending exteriorly of the housing for connection to jaws carried on an electrical component mountable in an electrical watthour meter socket. Degassing ports are formed between the cover and the sidewall of the housing to allow any arcing gasses generated within the interior of the housing to escape from the housing. A handle is mounted centrally on the cover. An ejector handle is movably mounted on the cover and carries an ejector arm to separate the housing from an attached electrical component. A method of removing and remounting a watthour meter in a meter socket is provided, including sequence steps printed on the face of the housing.

  • Patent number: 6478589
    Abstract: A safety shield for an electrical service apparatus is in the form of an enclosure surrounding in the apparatus jaw contacts. Latch members formed on the shield releasibly engage apertures in the apparatus housing to mount the shield in the housing. The latch members are configured to fill the apertures in the housing to prevent disengagement of the shield from the housing during removal of a watthour meter from the housing. In one aspect, the shield is provided with wire wrap members for winding up lengths of excess cables and conductors extending from a watthour meter. The wire wrap members include a pair of arms arranged about the periphery of the shield or spaced flanges on opposite sides of the shield. The wire wrap members also include a flange having an end extending over an aperture in the shield which acts as a strain relief for a conductor extending through the shield.

  • Publication number: 20020075622
    Abstract: An electrical service apparatus housing carries a plurality of line and load blade terminals and jaw contacts. Surge suppression elements are carried on a circuit board mountable within the housing and are connected to certain blade terminals and jaw contacts for conducting electrical surges to ground. Insulating barriers surround the jaw contacts and, also, fixedly position the circuit board in the housing. A switch element is energized when one of the surge suppression elements changes state and provides an externally transmittable signal indicative of the change in state of one of the surge suppression elements. An insulating safety shield surrounds the jaw contacts. A light transmissive guide carried on the shield has a first end disposed adjacent to a light source on the circuit board and an opposed second end visible exteriorly through the housing to provide an exteriorly visible indication of the state of the light source.

  • Patent number: 6152764
    Abstract: A watthour meter socket adapter has a housing formed of a base and unitary annular sidewall projecting from the base. Jaw blades are mounted in apertures in the base. In one embodiment, a spring clip is movably disposable in an aperture formed in each jaw blade to define a meter blade terminal receiving slot therebetween. In another embodiment, the spring clip is fixed to the jaw blade by a single mechanical fastener. Complimentary locator members are formed on the jaw portion and the spring clip for non-movably locating the spring clip relative to the jaw blade. A tab projects from the jaw blade for non-movably fixing the jaw blade relative to the base of the socket adapter. Flanges formed on the base fixedly engage the tab. The jaw blade may be formed of a single unitary jaw contact and blade terminal or a discrete jaw member and blade member. U-shaped support members are formed on the base for engaging opposite side edges of the blade members for non-movably fixing the blade terminal relative to the base.

  • Patent number: 6104586
    Abstract: A circuit breaker switch apparatus pluggable into a watthour meter socket includes at least one set of line and load contact terminals and a power disconnect for completing an electrical circuit between at least one line terminal and one load terminal. The power disconnect switch is responsive to a trigger signal to switch switchable contacts to an open position and maintains the switchable contacts in the open position as long as the trigger signal is present. The power disconnect switch is mountable in the socket adapter housing by a snap-in connection. Load jaw contacts are mounted on rigid bus bars which are connectable to the power disconnect switch by a snap-in connection. An insulating shield surrounds the line and load jaw contacts and conductors while providing apertures to allow the insertion of watthour meter blade terminals therethrough into contact with the jaw contacts.

  • Patent number: 6059605
    Abstract: A watthour meter socket adapter has front and rear housings which encompassingly surround jaw contacts, electrical conductors and terminals. Apertures in the front housing allow insertion of a meter blade terminal into the jaw contacts. The jaw contacts include a spring clip having a recess sized for slidably receiving one side of a conductor to dispose the conductor for direct contact with a meter blade terminal. At least two conductors overlay each other and are separated by an insulating pad. The terminals include a collar having a recess for partially receiving one side of a circular conductor or in the case of a rectangular bus bar conductor, a bore is offset to one side edge of the terminal collar for receiving a lower portion of the bus bar. The upper portion of the end of the conductor is folded over to form a flange overlaying a bottom portion of a first bore in the terminal collar and engages an external conductor.

  • Patent number: 5997347
    Abstract: A jaw blade contact for a watthour meter socket adapter includes a terminal with a blade end and an opposed jaw contact end. A spring clip is fixedly mounted on the terminal and has a jaw contact end opposed from the jaw contact end of the terminal for receiving a blade terminal of a meter there-between. Angled arms carried on the spring clip releasibly engage the base of the socket adapter housing to mount the jaw blade contact on the housing in a snap-on connection. In another embodiment, a spring clip engages apertures in a jaw contact formed of two folded over portions to mount the jaw contact in the housing. The housing has a mounting flange with a frangible portion conformable to different sized socket cover openings. An arcuate surge ground conductor is mounted on the housing sidewall by an integral bendable member which is movable from an in-line position to a mounting position extendable through an aperture in the housing.
