A power adapter configured to apply power to a device is disclosed. The power adapter comprises a contact element configured to receive power; a first outlet configured to receive the power and adapted to provide the power to the device; a recess for receiving a module that is removably coupled to the power adapter, wherein the module is adapted to generate control signals; and a control circuit coupled to the recess; wherein the control circuit controls the application of the power to the first outlet in response to the control signals.

A panelboard assembly for a harsh and/or hazardous environment is provided. The panelboard assembly includes a main breaker assembly, a first subpanel assembly, and a second subpanel assembly. The first subpanel assembly includes a first contactor assembly, and a first branch breaker assembly electrically connected to the first contactor assembly and configured to be electrically connected to a first group of loads. The first contactor assembly is configured to switch the first group of loads on and off all at once. The second subpanel assembly is electrically connected in parallel to the first subpanel assembly, and includes a second contactor assembly and a second branch breaker assembly electrically connected to the second contactor assembly and configured to be electrically connected to a second group of loads. The second contactor assembly is configured to switch the second group of loads on and off all at once.

A plug-in power adapter is described. The plug-in power adapter may comprise a plug having a plurality of prongs, wherein a first prong of the plurality of prongs is adapted to receive power; a transformer coupled to receive the power by way of the first prong of the plurality of prongs, wherein the transformer is adapted to generate a power signal on a power signal line coupled to the transformer; an input portion comprising a control button, wherein the control button is accessible by a user of the plug-in power adapter; and a plurality of contact elements on a surface of the plug-in power adapter and accessible by the user of the plug-in power adapter; wherein a contact element of the plurality of contact elements is adapted to receive a control signal.

A electrical distribution system has been developed to provide a remote central control point for individual circuits, and methods have been developed for retrofitting it to existing service panels or installing it into new service panels. This system provides a power circuit monitoring and control system that fits inside standard residential service panels, both new and retrofitted panels. The entire system can be retrofitted into existing breaker panel systems without the need of removing any permanent structure such as a wall. During this retrofit process, the panel cover on the existing distribution panel is first removed after the power to it is disconnected. The old breaker assembly is removed from the panel, and a circuit controller is then installed in the now available space within the panel. A new service panel enclosure with a circuit breaker assembly is installed directly over top of the enclosure.

A meter hub safety isolation service entrance disconnect switch includes an enclosure configured to mount outside a building and protect contents of the enclosure from ingress of solid foreign objects or the ingress of rain, sleet, or snow and that will be undamaged by the external formation of ice on the enclosure. The enclosure has a dead front cover and removable outside cover in which the outside cover is marked to inform a first responder that the enclosure contains a disconnect switch. The disconnect switch is operable upon removal of the outside cover while the dead front cover remains in place and includes a multi-pole switch having poles sufficient to convey power, neutral and ground as may be required by an electrical power source for a load center serving the premises, the switch opening poles for power and neutral upon actuation, while maintaining the ground of the premises wiring.

A plug-in power adapter is described. The plug-in power adapter may comprise a plug having a plurality of prongs, wherein a first prong of the plurality of prongs is adapted to receive power; a transformer coupled to receive the power from the first prong of the plurality of prongs, wherein the transformer generates a power signal on a power signal line coupled to the transformer; a plurality of contact elements accessible on the plug-in power adapter by a user of the plug-in power adapter; and a wireless communication circuit adapted to receive signals using a wireless communication protocol; wherein a contact element of the plurality of contact elements is adapted to receive a control signal.
