What is an AC Generator (Components also)? - Answer-A device that converts mechanical energy to electrical energy. Consists of magnets, an armature, slip rings, brushes, and some type of resistive load. What is Siemens AG? - Answer-A parents company of Siemens Industry Inc. and a leading supplier of electrical and electronic equipment. How much power is needed for a residential user? - Answer-240 volts and single-phase power What are inverters/microinverters? - Answer-Converts AC to DC What is a meter? - Answer-Determines how much electricity is used for billing. What is a load center? What does it consist of? - Answer-An industry term used to identify a type of panelboard used in residential or light-commercial applications. It consists of an enclosure, interior, and a trim. What is a circuit breaker? - Answer-Manually energizes and de-energizes a circuit and overcurrent protection for the connected circuits. What are arc faults and ground faults? - Answer-Arc Fault: Electrical faults which result when current flows in unintended ways. Ground fault: A condition where current takes an undesirable path to ground. What are the types of panels available from Siemens? - Answer-Riser Panels (high-rise applications), Spa Panels (Outdoor Applications w/ GFCI), Temporary Power Outlet Panels (Temporary service equipment during construction) What type of disconnects does Siemens manufacture? - Answer-Fused, non-fused, and molded switch disconnectsWhat are the ways to produce electricity? - Answer-Turbines (Coal, Oil, and Uranium which heats water into steam and turns a turbine) and Renewable Energy Sources (Hydroelectric, solar, wind, etc.) How is power transferred residentially? - Answer-Through a trunk and drop cable which goes through a meter and eventually goes through a load center.
