摘要： A punch set for use with a punch tool to punch material from a wall of an electrical box. The punch set has a punch with a cutting section, and a die defining a cavity that is configured to receive the cutting section. The cutting section may have an annular or circular portion and a plurality of keyway forming portions each extending radially from the annular or circular portion. The cutting section of the punch may be insertable into the cavity of the die in a single orientation. The die may have a protrusion receivable within a recess of the punch when the cutting section is received in the cavity. One of the die or punch may have an extension that is receivable in a single orientation within an opening in the other of the die or punch.

摘要： A plumb adjuster configured to plumb an electrical enclosure mounted to a vertical or nearly vertical surface. The plumb adjuster includes a side wall with a threaded outer surface that is configured to engage a threaded surface of the electrical enclosure. The side wall defines a cavity accessible through a first opening at a first end that is configured to receive the head of a fastener for mounting the electrical enclosure to the surface. An end wall coupled to a second end of the side wall has an outer surface configured to engage the surface to which the electrical enclosure is mounted. The end wall has an inner surface configured to engage the head of the fastener. The end wall defines a second opening that extends through the end wall, and the second opening is configured to receive a shank of the fastener.

摘要： An electrical box having an enclosure and a conduit hub adapter that is configured to engage a portion of the enclosure. The enclosure defines an opening that is configured to receive an electrical power conductor. The conduit hub adapter is movable with respect to the enclosure from a disengaged position to an engaged position. A retainer may be positioned adjacent the opening to engage the conduit hub adapter when in the engaged position and secure the conduit hub adapter to the enclosure. The conduit hub adapter may be configured for engagement with the enclosure in a single orientation. The retainer may be configured so that it may only be disengaged from the conduit hub adapter from within an interior space of the enclosure. The enclosure may have a second opening with a second conduit hub adapter configured to engage the enclosure adjacent the second opening.

摘要： Aspects of the present disclosure involve systems, methods, and the like, for an automatic transfer switch (ATS) of a power system. The ATS allows for switching between two or more power systems while preventing back-feeding of the power systems. To provide the safety features of the ATS, a safety circuit and control board may be implemented with the magnetic latching relays to control the actions of the latching relays and provide the switching function of the ATS. In one particular embodiment, the safety board comprises one or more electromechanical relays positioned between the controlling electronics of the control board and the magnetic latching relays. The safety board design contains measures to ensure it still functions if one of the disconnect switches is not connected, if one of the connections to a first load phase, a second load phase or neutral is lost and if the main control board is not connected.

摘要： Aspects of the present disclosure involve systems, devices, methods, and the like, for a transfer switch of a power system incorporating a self-powered electronic meter that provides a learn function to determine the maximum amount of power an attached generator can provide, and adjust a power meter display associated with the switch accordingly so that the indicator of the display may be used for any size generator and display the full range of the generator. The learning function is activated and a user turn on devices and loads in the load center until the generator stalls. A microcontroller records the max generator power that was measured before the generator stalled and save it to non-volatile memory as the new 100% setting for that particular generator connected to the transfer switch.

摘要： A meter box with insulation-piercing wire termination connectors is disclosed. Each connector includes a conductor receiver having an inner surface that defines a channel sized to receive an electrical power conductor comprised of a conductive wire encased within insulation. At least one protrusion projects from the inner surface of the conductor receiver into the channel and has a continuous edge spaced apart from the inner surface that is positioned to pierce the insulation and electrically contact the conductive wire when the electrical power conductor is clamped within the conductor receiver. Each connector may also include a meter jaw configured to receive a connector blade of an electric meter, wherein the meter jaw is mechanically and electrically connected to the conductor receiver.

摘要： An insulating block configured for attachment to an electrical structure without the use of a tool. The insulating block is formed from an electrical insulator. One of the electrical structure and the insulating block may have a clip that is configured to engage a catch surface on the other of the electrical structure and the insulating block without the use of a tool. An opening or recess of the electrical structure may be configured to receive a portion of the insulating block having the clip or catch surface, and the portion of the insulating block may move within the opening or recess from a disengaged position to an engaged position, in which the clip engages the catch surface to securely attach the insulating block to the electrical structure. The electrical structure may be a meter socket enclosure. The combination of the insulating block with the electrical structure.
