Health care facility electrical systems are complex, difficult to design, expensive to build, and subject to a plethora of codes and standards. They must be reliable and still operable in emergency situations.

This ASHE handbook, which includes numerous diagrams, provides updated information on distribution systems, overcurrent protection, essential electrical systems, patient care areas and electrical safety, power quality, lighting, and maintenance testing. New material in this volume covers selective coordination and arc flash and parallel operation of generators.
