Hospitals and healthcare facilities have an emergency power supply in case of a grid outage, provided by an emergency generator. According to the Mexican Official Standard NOM-001-SEDE-2012, Article 700-3, load bank tests must be conducted to verify all emergency power and lighting systems under the maximum load conditions allowed for the generator. This is to prevent power outages in life-support and patient protection equipment: fire detectors, safety lights, elevators, etc. The best way to test the emergency generator without affecting service quality—such as shutting down sensitive equipment, issuing service notes, etc.—is to perform maintenance on the emergency generator using a load bank. The load bank should be capable of simulating the generator’s load increase, such as the startup of an elevator, surgical equipment, medical devices, etc., and confirming the emergency generator’s ability to take over in the event of a main grid outage.
