Life Safety Vertical Movement Emergency Power Package
Calculates source-bound emergency-power metrics from a deterministic SSC-08 task-owned source pack. The template combines critical connected load, diversified emergency load, generator margin, battery bridge, feeder current and voltage drop, load shedding, and an overall synthetic pass score.
with-tool: The model is given an executable Python calculator script.

Difficulty
Each template is sampled at three tiers. Harder tiers may hide inputs, forcing the model to infer them from the scenario description.
All inputs remain visible at every tier
For this template, difficulty scales through parameter and scenario ranges rather than hidden information.
- easy:
- All source-pack values given for the SSC-08 emergency-power package
- medium:
- All source-pack values given for the SSC-08 emergency-power package
- hard:
- All source-pack values given for the SSC-08 emergency-power package
