Abstract: Devices, systems and methods are provided to improve communication of switch sensor and status signals between a medium voltage overheard switchgear and an intelligent electronic device (IED). A switchgear interface device is deployed proximally to a switchgear and/or junction box situated at a distal end of a utility pole. The switchgear interface device (SID) receives, processes and combines sensor signals and status signals from switches in the switchgear with metadata for transport as digital signals to an IED mounted at the other end of the utility pole. The cabling for sensor and status signals between the SID and the IED can be fiber or Ethernet. The digital signals can be formatted using the IEC61850 standard. The SID can have drive electronics and send open and close command signals to the switches to eliminate the need for a multi-pin connector cable for transport of switch power signals from the IED.

Abstract: A battery management system may include a battery. The battery management system may further include a central charging station configured to: provide power to charge the battery, and output an alert to a user of the battery in response to the battery not being returned to the central charging station within a predetermined time after being removed.

Abstract: A cover plate that is connectable to an electrical box includes a body configured to mount to a stud, a brace assembly, or in a gang application on opposite sides of the stud. A method of attaching a cover plate to a stud includes positioning a stud tab extending from a body on a first side of the stud and moving the body to position a projection extending from the body on a second side of a stud so that the body snaps on over the stud allowing for insertion of one or more fasteners.

Abstract: An electrical box assembly having an electrical box and a cable connector is provided. The cable connector includes a mounting bracket cable retaining member and a cable stop. The mounting bracket is secured to or integral with a side wall of the electrical box. The cable retaining member is secured to the mounting bracket and has a cable gripping portion extending into a cable receiving zone of the box. The cable stop extends from a bottom wall of the electrical box into the cable receiving zone. The cable stop permits one or more electrical wires from an electrical cable to pass through the cable stop while blocking sheathing of the electrical cable from passing through the cable stop.

Abstract: A bracket for mounting an electrical box to a brace includes a body portion with a first end, a second end, and a channel disposed between the first end and the second end that extends along a channel axis. A first foot extends from the first end in a direction substantially perpendicular to the channel axis. A second foot extends from the second end in a direction substantially perpendicular to the channel axis. A first tab extends from the channel in a first tab direction substantially perpendicular to the channel axis. The first foot and the second foot can be received within the electrical box and support a weight of the electrical box without any additional fasteners. The first tab is bendable to a second tab direction that is substantially perpendicular to the first tab direction and to the channel axis.
