Worked Example
Verified calculation
Given:
- Life Safety Egress Lighting Load = 12.5
- Fire Alarm System Load = 1.8
- Emergency Communication System Load = 0.9
- Critical Branch Receptacle Load (Patient Care Areas) = 8.2
- NEC-Compliant Diversity Factor for Simultaneous Life Safety Loads = 1
Expected Result:
- Minimum Required Emergency Generator Capacity = 23.4
Engineering Interpretation:
Under the given input conditions, the calculated result is: Minimum Required Emergency Generator Capacity = 23.4 kW.
The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from deterministically validated test cases.
Formula / Method
minimum required emergency generator capacity = (life safety egress lighting load + fire alarm system load + emergency communication system load + Patient Care Areas) * nec-compliant diversity factor for simultaneous life safety loadsMinimum Required Emergency Generator Capacity.
