摘要： The present disclosure is directed to preventing serious injury or death by electrocution due to contact with a power source, such as an alternating current (AC) voltage source. Methods and apparatus consistent with the present disclosure may controllably provide an electrical voltage to an electrical conductor for a period of time and then remove that voltage from the electrical conductor before providing the electrical voltage to the electrical conductor a second time. By initially connecting the electrical voltage to the conductor, then removing that electrical voltage from the conductor before re-connecting that electrical voltage to the conductor, methods and apparatus consistent with the present disclosure allow a person to let go of the electrical conductor before the person is seriously injured or killed by an electrical shock in an instance where the body of the person is in physical contact with the electrical conductor.

摘要： The present invention is a smart electrical system comprising a smart control panel connected to various electrical interfaces. Each electrical interface is inbuilt with at least one IC chip to identify it. The smart control panel comprises a processing unit to process information from various electrical interfaces and load connected to each electrical interface. The processed information is displayed on the display unit, as at least one menu list, that allows the user to select and control various electrical interfaces from panel itself. The smart control panel allows the user to reset the circuit breaker box in case if it is tripped due to overload. The panel monitors each electrical interface and alerts user when overload or marginal load condition occurs.

摘要： A circuit breaker having a housing with an accessory cover includes an accessory cover interlock assembly that trips the circuit breaker upon removal of the accessory cover. The accessory cover interlock assembly includes a plunger rotatable from an initial install position to an engaged position that moves a trip lever into a de-energize position (tripping the circuit breaker) upon removal of the accessory cover. The accessory cover interlock assembly prevents the circuit breaker from being reset while the access cover is removed. The accessory cover interlock assembly automatically resets upon re-attachment of the accessory cover to the circuit breaker housing. Methods of forced safety tripping in a circuit breaker are also provided, as are other aspects.

摘要： Plug-on neutral circuit breakers include a housing, a plug-on neutral clip with legs extending out from the housing and a mechanical coupler of a lockout latch assembly in the housing coupled to a latch link and the plug-on neutral clip to move the mechanical coupler in response to a change in position of the plug-on neutral clip between first and second positions associated with partially and fully installed orientations to thereby provide a lockout state when not in the second position.

摘要： Thermally conductive assemblies that provide a heat conduction path include at least one thermally conductive inner member with longitudinally opposing first and second ends and an open center channel and an outer member surrounding the at least one thermally conductive inner member. The outer member is sufficiently flexible to expand outward in response to an outward force applied by the at least one thermally conductive inner member. The at least one inner member can be a plurality of cooperating inner members that have inner surfaces that align to form an inner perimeter surrounding the open center channel.

摘要： A load center includes an arc fault circuit interrupter comprising a plurality of contacts, an operating mechanism for separating the contacts, and an arc fault trip mechanism to generate a trip signal in the event of an arc fault detection. The load center also includes a neutral link electrically connected to the arc fault trip mechanism and the plurality of contacts. The load center further includes a mounting rail operatively coupled to the arc fault circuit interrupter, the arc fault circuit interrupter directly supported by the mounting rail. The load center yet further includes a neutral busbar and a plug-in neutral conductor electrically connecting the mounting rail to the neutral busbar.

摘要： A plastic-shell-encased circuit breaker having an automatic locking function comprises a plastic-shell-encased circuit breaker body, a user input unit for inputting a lock code or an unlock code; an authentication processing unit for receiving the lock code or the unlock code from the user input unit, and for outputting a control signal after authentication; a locking action unit for receiving the control signal from the authentication processing unit, and for enabling the plastic-shell-encased circuit breaker body to produce a self-locking or unlocking action. Utilization of the plastic-shell-encased circuit breaker having the automatic locking function is capable of preventing the circuit breaker from being switched on without careful consideration, so as to ensure security of operators.
