Gas and Gasoline Generators Key Terms

Learn about the size and specifics of gas and gasoline generators

Gas and gasoline generators are used as a backup power source for homes and businesses. A natural gas generator has the capacity to handle larger jobs while gasoline generators are a smaller, portable size good for short periods of use. Both types of generators work well to provide a low maintenance and cost efficient option for backup power sources. Gasoline generators are typically produce 7kW of power or less. Power produced by natural gas generators can range from 7kW to 15kW.

 

Transfer switch

A transfer switch is a switch that allows changing from the primary power sources to a secondary power source. Using a transfer switch with a generator helps to maintain safe switching from different power sources and keeps both sources isolated from each other.

Sizing

Sizing is an important concept for gas generators. Proper sizing prevents underproduction or overproduction of power for the needs of the space.
Try: US Carburetion provides a sizing chart and information on sizing for propane and gas generators.

Heat rise

Heat rise is a process where the amount of heat rising from a generator when in use is directly related to the longevity of the generator. Heat rise is also related to the amount of copper present in the generator's alternator.
Try: Jobsite Generators provides information on ratings on generator heat rise.

Voltage

Voltage is the rate that energy is taken from a source to produce an electric flow inside a circuit. Voltage is expressed in volts (V).
Try: Electricity Central provides an explanation of voltage and how to measure it.

Closed frame generator

Portable gasoline generators have the ability to produce lots of noise, so manufacturers produce open and closed frame generators. The closed frame generator offers noise reduction to the level of sound comparable to two people talking.
Try: Aurora Generators provides specs on a type of gasoline generator with a closed frame designed for quieter conditions.

Kilowatt (kW)

The kilowatt of an electrical product or appliance is the measure of power the product generates. One kilowatt is equal to 1,000 watts. Kilowatts are often used to size generators for an area.
Try: Gillette Generators provides a sizing chart for generators determined by the kilowatts that need to be produced in order to accommodate a certain amount of essential appliances.
