Systems, apparatus, methods, and techniques of assembly of discrete modules of a control panel are disclosed. The modules can be independently wired, tested, and installed into a control panel. Module definitions are defined specifying components to perform the electrical function, a mechanical arrangement of the components, electrical connections, and logical interactions of the module. A bill of materials can be generated based on a designation of a set of modules for a control panel and the module definitions. Modularly assembled control panels are disclosed. An assembly frame is described herein for temporarily mounting components of a module for independent assembly of a control module and for eventual removal and installation into a control panel frame. The assembly frame may include a faceplate frame and side frames and temporary mounting features.

Control panel assembly methods and techniques

Disclosed herein are various embodiments of devices and related methods for detecting an electrical arc event using a motor management relay and for suppressing the electrical arc event. The motor management relay may incorporate an optical arc-flash sensor configured to detect an optical event. Control logic may analyze the optical event and determine whether the optical event corresponds to an electrical arc event. When an electrical arc event is detected an instruction may be issued via a control port in communication with the control logic to implement a protective action. According to various embodiments, a plurality of sensors for monitoring electrical characteristics of a motor may also be in communication with the control logic. Input from the sensors may be analyzed in order to determine whether the optical event corresponds to an electrical arc event.

A connection system for electrically and mechanically connecting a DSX jack to a jack assembly, the system including a male connector with a plurality of elongated conductors electrically connected to the jack or the jack assembly, a dielectric shroud around the elongated conductors, the shroud having slits adjacent each of the elongated conductors, and a female connector with a female dielectric edge connector with an internal cavity with guides therein, a plurality of tuning fork contacts seated within the guides in the internal cavity and electrically connected to the other of the jack or the jack assembly, the tuning fork contacts including two prongs with a conductor aperture between the two prongs, the conductor aperture corresponding to the elongated conductors of the male connector, and the tuning fork contacts positioned to slidably mate with corresponding ones of the plurality of elongated conductors in the male connector. The male connector slides into the female connector and electrical contact is thereby made between the tuning fork contacts and the corresponding elongated conductors in the male connector.
