Most standby generators run less than 50 hours each year. This means they only require a preventative maintenance level 2 (PM2) once per year. A PM2 will consist of an inspection on the overall condition of the generator. Click here to learn more.
An automatic transfer switch is a piece of equipment designed to manage electrical power between two sources by continuously monitoring utility power and, in the event of a power outage, automatically starts the standby generator. Learn more about our ATS services here.

The basic rule of thumb is that a diesel generator will burn 7-gallons of diesel fuel for every 100 kW of output (load).
Example: a 300-kW generator will burn 21-gallons per hour at 100% load
The ATS has many time settings programmed into it. Once utility returns, there is a time setting that waits for a certain amount of time (usually 20-30 minutes) of clean power before it transfers back from generator power to utility power. If utility returns for 10 minutes and there is another small brownout, that 20–30-minute timer resets, causing the generator to run longer. This time setting is in place to prevent the generator from starting and stopping numerous times as that is not good for the engine. After 20-30 minutes of clean, uninterrupted power, it will transfer back to utility and the generator will shut off after a 5-minute cool down.
