Abstract: A power distribution system includes a first intelligent circuit breaker; a plurality of second intelligent circuit breakers, the second intelligent circuit breaker is structured to transmit the circuit breaker information to the first intelligent circuit breaker; and an energy monitoring device coupled to the first and second intelligent circuit breakers and structured to receive the circuit breaker information, the energy monitoring device including a dynamic coordination system structured to: (i) determine whether an adjustment to configuration setting of an intelligent circuit breaker is required based at least in part on the circuit breaker information, (ii) identify the intelligent circuit breaker with the configuration setting required to be adjusted based on a determination that the adjustment is required, and (iii) transmit an alert to user, indicating that the adjustment to the configuration setting of the identified intelligent circuit breaker is required and device address of the identified intell

Abstract: A method for controlling an operating discharge pressure in a multi-purpose HVAC system including an outdoor unit, and an indoor unit, the HVAC system including a plurality of flow control valves configured to isolate the indoor unit from the multi-purpose HVAC system, a compressor and a controller, operably coupled to a water heater module, the water heater module including at least one valve, the controller executing a method including operating the multi-purpose HVAC system in a water heating mode, monitoring the operating discharge pressure from the compressor; and generating a signal commanding at least one of the plurality of control valves to isolate the indoor unit from the outdoor unit and water heating module and direct high pressure refrigerant to the indoor unit when the operating discharge pressure is greater than or equal to a predetermined pressure value.

Abstract: An apparatus includes a switch having alternately open and closed conditions, and a shunt trip mechanism configured to detect and respond to an electrical fault condition. The apparatus further includes an operating mechanism including a spring assembly. The operating mechanism is actuatable manually to deflect the spring assembly into a stressed condition, and is actuatable automatically in response to the shunt trip mechanism to shift the switch into the open condition upon return deflection of the spring assembly from the stressed condition. The spring assembly may include springs connected in parallel.
