Diesel Generator Key Terms
Learn about diesel generators and keep the lights on when power goes outWhether you need portable power at a job site, need to ensure an uninterrupted supply of power at a manufacturing plant or just want backup for when the lights go out at home or at work, learning diesel generator key terms will help you choose your generator wisely.

Watts or kilowatts
Run timeRun time is how long the generator's fuel will last at capacity. To increase your run time, choose a generator with a larger fuel tank or a smaller generator with the same-sized fuel tank.
Utility or mains frequencyThe utility or mains frequency is the frequency in Hertz (Hz) at which power is supplied from power plants to consumers. Although the frequency in most of the world is 50 Hertz, the frequency in the U.S. is 60 Hertz. Unless your equipment is designed to run at both 50 and 60 Hertz, make sure you buy a generator that matches the utility frequency in your part of the world.
Standby generatorIf you can't afford a second of downtime, you can buy a diesel generator that automatically kicks in when the main power goes out. These standby generators are usually larger than portable generators because they're intended to power entire buildings or critical systems such as elevators.
Trailer-mounted or towableTrailer-mounted, or towable, diesel generators are designed to be towed by a truck to a worksite. They are commonly used in construction and are popular rentals.
Emergency or portableEmergency, or portable diesel generators, are used most often by homeowners or small businesses in the event of an unexpected power outage. Portable generators are usually small enough to be moved by one person and have wheels for added convenience.
