30 kW Emergency Standby Power Generator

About

An electric dynamo that generates, especially a machine that converts mechanical energy into electrical energy.[1]

Monthly testing

1. To meet federal certification and state licensure requirements, healthcare facilities must exercise their emergency generators under load at least monthly [see NFPA 110(99), Sec. 6-4.1; NFPA 110(02), Sec. 8.4.1]. There are a number of ways to comply with this requirement:

a. The base requirement is that generators be exercised for a minimum of 30 minutes* using one of the following methods [see NFPA 110(99), Sec. 6-4.2; NFPA 110(02), Sec. 8.4.2]:

i. Under operating temperature conditions and at not less than 30 percent of the generator’s nameplate kW rating. A 100 kW generator, for example, would need to be exercised under a load of at least 30 kW to meet this requirement.

• Normal operating temperatures are set by the manufacturer. Something to consider when scheduling your monthly tests is that your particular generator may not reach operating temperature in 30 minutes* and that running the generator for short periods of time may be harmful to the engine. You also want to make sure that the generator runs long enough to ensure that all engine parts are properly lubricated.

ii. Loading that maintains the minimum exhaust gas temperatures recommended by the manufacturer (it is unlikely that minimum exhaust gas temperatures will be reached if the generator isn’t carrying a load equivalent to at least 30 percent of the generator’s nameplate kW rating). [2]

*Note: Warm-up and cool-down times do not count toward the required 30 minutes
