Communication enabled circuit breakers are described. Methods associated with secure communication between communication enabled circuit breakers and a panel system are described. Additionally, methods for commissioning and decommissioning such communication enabled circuit breakers in the panel system are described. The communication enabled circuit breakers may be paired with a controller and information regarding such breakers can be added to a database.

Secure communication for commissioning and decommissioning circuit breakers and panel system

Wireless communication enabled circuit breakers are described. Methods associated with such wireless communication enabled circuit breakers are also described. The wireless communication enabled circuit breakers may controlled by a remote entity. The remote entity may wirelessly case the wireless communication enabled circuit breakers to trip.

Communication enabled circuit breakers

A zero-crossing detection method, and devices incorporating the method, enable a selectively enabled bias to pull-up a zero-crossing signal, thereby enabling monitoring of the zero-crossing of both half-cycles of the alternating current (AC). This improves synchronization of the device in noisy environments and enables the detection of dimming problems during either half-cycle. Aspects can detect improper dimmer firing events on either polarity of the power cycle and restore normal dimmer operations when needed.

Dimmer with improved noise immunity

A dimmer is provided for controlling power to a load, the dimmer having a ground leakage power supply deriving power from a connection of the dimmer to ground. The power supply may be a switching-mode power supply that can be the sole or primary power supply to power operation of the dimmer, including operation of the controller.

Ground leakage power supply for dimming applications

There is set forth herein a dimmer circuit for controlling delivery of input line voltage to a load. The dimmer circuit can include a switch coupling an input line voltage terminal to a load terminal. The dimmer circuit can be operative to provide one or more switch firing control scheme for latching the switch.
