Wherein the bellows assembly reciprocates a moveable contact of the vacuum interrupter to prevent arcing between a pair of contacts and biasing the pair of contacts apart from each other.
The present disclosure provides descriptions of configurations for wire connectors used to splice low voltage electrical conductors or to splice high voltage electrical conductors. The wire connectors may be coupled to form a wire connector assembly. Each wire connector includes a base, a cover, a first cover coupling assembly and a second first cover coupling assembly. The base has an upper wall and a lower wall and can be divided into a first end portion, a second end portion and a central portion between the first end portion and the second end portion. The cover has a main cover member, a first movable cover member movably connected to a first side of the main cover member and a second movable cover member movably connected to a second side of the main cover member. The main cover member includes a plurality of contact chambers, where each contact chamber includes at least one electrical contact positioned within a cavity of the contact chamber. The first cover coupling assembly is associated with the first end portion of the base and the first movable cover member of the cover. The second cover coupling assembly is associated with the second end portion of the base and the second movable cover member of the cover. The cover assemblies are used to releasably couple the movable cover members to the base.
An electrical box assembly and cable connector are provided. The cable connector includes a connector housing and a cable retaining member that releasably secures an electrical cable within the connector housing. The electrical box assembly includes an electrical box and a cable connector. The electrical box assembly may also include a box separator.
H02G 3/16 - Distribution boxes; Connection or junction boxes structurally associated with support for line-connecting terminals within the box
H02G 3/06 - Joints for connecting lengths of protective tubing to each other or to casings, e.g. to distribution box; Ensuring electrical continuity in the joint
H02G 3/08 - Distribution boxes; Connection or junction boxes

SYSTEM AND METHOD FOR MONITORING POWER CONSUMPTION OF AN APPLIANCE
A method for monitoring power consumption of an appliance within a space is provided. The method includes obtaining a first set of data indicative of power consumption of the appliance during an interval of time and determining a profile indicative of power consumption of the appliance based, at least in part, on the first set of data. The method includes obtaining a second set of data indicative of power consumption of the appliance subsequent to obtaining the first set of data. The method includes determining whether power consumption of the appliance deviates from the profile based, at least in part, on the second set of data. Furthermore, in response to determining power consumption of the appliance deviates from the profile, the method includes providing a notification indicative of power consumption of the appliance deviating from the profile.
