# Fuse and load-curve comparison
# Scope: Operating current versus supplied derated fuse current; no trip-curve coordination solve.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

check continuous-current screen: operatingCurrent <= continuousBudget

scenario alternative: operatingCurrent = 4 A
