Pump Station Mcc Cable Protection Package

Calculates deterministic SSC-05 pump station MCC metrics from a task-owned synthetic source pack. The template combines pump motor current, starting current, cable ampacity derating, voltage drop, overload margin, short-circuit margin, 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-05 pump station MCC package
medium:: All source-pack values given for the SSC-05 pump station MCC package
hard:: All source-pack values given for the SSC-05 pump station MCC package
