As per NBC 2016, which of the following is considered an essential load that must be connected to an emergency power system?
Answer & step-by-step solution
Fire pumps and fire alarm systems are life-safety loads and must remain available during loss of normal power, so they are connected to emergency/standby power arrangements as required by building fire-safety design. General office loads and decorative lighting are not comparable essential loads.
Concept & Reasoning
Emergency electrical systems prioritize functions needed for evacuation, fire detection, firefighting and critical safety. Fire pumps maintain hydrant/sprinkler pressure and fire alarms detect/annunciate emergencies. Their supply architecture typically includes dedicated feeders, automatic transfer and backup source provisions appropriate to the applicable code.
How to Solve It in the Exam
Fire detection + firefighting equipment = essential emergency loads.
Important Exam Point
Code details vary by occupancy/building height; keep the life-safety principle central.
Quick Trick
Fire detection + firefighting equipment = essential emergency loads.
Common Mistake
Treating convenience loads such as office workstations as equal to fire-protection loads.
