An apparatus includes an enclosure, a power switch, an absence of voltage detector controller, and an absence of voltage detector. The power switch is mounted inside the enclosure and configured to switch electrical power from a line-side power line to a load-side power line. The load-side power line is configured to transfer the electrical power outside of the enclosure to an industrial control panel. The absence of voltage detector controller is configured to determine a presence and an absence of each of a plurality of phases of the electric power on the load-side power line inside the enclosure. The absence of voltage detector is visible from external to the enclosure, has a switch, and is configured to illuminate one or more lamps indicating the absence of the electrical power on a corresponding one or more of the plurality of phases in response to a pressing of the switch.

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.

A breaker panel cover extension can be installed above or below a breaker panel and can hide imperfections or openings in drywall immediately above or below the breaker panel. The cover extension can include a panel member having a top edge, a bottom edge, a left edge, and a right edge defining an area of the panel member. The panel member having a front face and a rear face. A thin and narrow bottom flange extends downwards from the bottom edge and away from the panel member. The thin and narrow flange can extend along the length of the bottom edge. On the rear face of the panel member, below the top edge, two or more brackets can be coupled to the rear face of the panel member. Each bracket can have a coupling member configured to engage the cover extension to the drywall.
