For healthcare facilities, certain functions must be restored within 10 seconds of loss of normal power, including those dedicated to life safety functions as well as critical equipment, such as fixed equipment in surgical/operating rooms.

To meet the 10-second power requirement, emergency sources of power are supplied to satisfy the required loads through automatic or manual transfer switches. The transfer switches vary from non-delayed automatic, delayed automatic or manual transfer depending on the requirements of the specific brand of the essential electrical system they are feeding.

Routine maintenance must be conducted to ensure the emergency power can meet the 10-second power restoration. Monthly testing of the emergency power source is required under load for 30 minutes. It is recommended at least 12 times per year, at intervals between 20-40 days. At a minimum, the entire emergency power supply system must be tested once every three years continuously for four hours.

As healthcare facilities rely on advanced technology for state-of-the-art patient care, partners like RTM Engineering Consultants will continue to bring their expertise to bear for healthcare clients like ProHealth Care.
