Amperage: The intensity of an electric current that is measured in amperes (Amps).


Amps (A): Amount of electricity or current flowing through a wire  


dBA: A-weighted decibel that measures the sound level in the air as perceived by the human ear


Frequency: The uniform periodic change in amplitude or magnitude of an alternating current


Hertz (Hz): Unit of frequency measured in cycles per second


Inverter Generator: Typically a three phase generator that converts variable frequency AC into DC and then "inverts" it back to AC.


Kilowatts (kW): A measure of 1,000 watts of electrical power


Portable Generator: Power source to provide power at a location where there is no available primary power


Running Watts: The continuous power produced to keep items running


Single Phase: An alternating current that produces a single, continuous alternating voltage


Standby Generator: An automatic secondary source of power designed to automatically turn on when a primary source is lost


Starting Watts: The momentary electrical current the generator can provide to start electric motors, per Briggs & Stratton 628K. It does not represent the power required to continuously run electrical loads. It is the maximum current that can momentarily be supplied when starting a motor, multiplied by the generator's rated voltage.


Symphony® II Power Management System: Briggs & Stratton’s patented technology that allows a homeowner to utilize a smaller standby generator to provide whole house power


Three Phase: An alternating current that produces three separate alternating currents of the same voltage but is offset in time by a third of a period  


Transfer Switch: An electrical switch that can be either automatic or manual that switches a load between two sources. The sources are typically the utility and the generator.


Voltage: An electromotive force or potential difference expressed in volts


Watt: Corresponds to the power in an electric circuit in which the potential difference is one volt and the current one ampere
