Abstract: An arc fault circuit interrupter (AFCI) module includes a plug portion, a probe receiving portion and an AFCI test actuator for initiating a test of an AFCI protected circuit. More specifically, the plug portion includes a plurality of prongs configured to matingly engage with a standard three-prong receptacle. With this construction, upon engaging the plug portion with a AFCI protected receptacle, manipulation of the AFCI test actuator will cause a properly operating AFCI device to trip, i.e., terminate power to the AFCI protected receptacle. The module can also be provided with an AFCI circuit. The module can then be employed to protect an electrical device that is plugged into an unprotected circuit. The probe receiving portion is adapted to interconnect and expand the testing capabilities of a standard receptacle tester or, alternatively, be interconnected with various test probes associated with standard voltage testers.

Abstract: An automated energy saving system dispenses HVAC energy from a common energy source to a set of utility zones, typically rooms in a house or commercial building which are dispersed at different locations remote from the energy source, typically a roof top unit. Each utility zone selects locally established operating conditions as operating parameters serviced at a control center, typically located at the energy source site, to distribute available HVAC energy to the independent utility zones of the set in an energy saving mode of operation. The remote utility zones communicate with the common controller by wiring or wireless communication links. At the energy source energy is distributed by off-on control of individual energy conduits to the individual utility sites.
