The present disclosure envisages a heat-absorbing-and-dissipating jacket (80) for a terminal (100) of an electrical device (1000). The jacket has a body (81) configured to at least partially contour walls of the housing (10) of the terminal (100) and the jacket is made of a heat-absorbing-and-dissipating material. The body (81) of the jacket has a lower portion (86) extending operatively below the housing (10) of the terminal (100). The body (81) of the jacket also has an upper portion (88) extending operatively above the housing (10) of the terminal (100). The jacket (80) of the present disclosure is a cost-effective means which allows maximum heat absorption and dissipation from an enclosed electrical device and can be incorporated in an existing design of an electrical device.

A residential circuit breaker is provided with means for showing proper installation of a panel wire to ensure that an installer/a contractor is aware that the panel wire has been fully inserted into a circuit breaker lug. The residential circuit breaker comprises a circuit breaker lug having a lug body and a lug body screw. The residential circuit breaker further comprises a panel wire install indicator to indicate proper insertion of a panel wire in the lug body by providing a visual indication to an installer/contractor that the panel wire has been fully inserted in the circuit breaker lug during and after installation. The panel wire install indicator includes a panel wire indicator lever wherein the panel wire indicator lever can indicate if the panel wire has been installed properly and wherein there is a visual indication if the panel wire is no longer present in the lug body.

A terminal for an electrical device having a feature to receive an auxiliary connection, the terminal including a cavity including an opening for receiving a first wire, and a terminal device positioned at least partially in the cavity, the terminal device including a distal portion extending external to the cavity, wherein the distal portion of the terminal device is configured to receive a connector of a second wire.

An inverter and a direct-current switch assembly are provided. The direct-current switch assembly comprises a direct-current switch and a connecting terminal unit, the direct-current switch and the connecting terminal unit being integrated on a mounting main body, the connecting terminal unit can realize connection and disconnection of a first terminal and a second terminal by means of the direct-current switch, and the direct-current switch is directly connected to a direct-current cable by means of the first terminal. The direct-current switch and the connecting terminal unit of the present invention are integrally mounted, not requiring a cable connection.

An electrical device includes a case defining an interior space. The case includes a sidewall and a cover. The sidewall defines an opening therethrough to provide access to the interior space. The electrical device also includes a power connector coupled to the case and disposed at least partially within the interior space. The power connector is coupleable to a cable extending through the opening into the interior space of the case. The electrical device further includes a shield removably coupleable to the case. The shield includes an engagement feature and a wall. The engagement feature is arranged to engage the case. The wall is arranged to at least partially cover the opening when the shield is coupled to the case such that the wall and the cable are spaced apart a distance that is less than a width of the opening when the cable is coupled to the power connector.
