Axiom type
LLM classification basis: function-based → ≡
Switchboard identity is fundamentally defined by its function to control, connect, and disconnect electrical circuits through switches and control apparatus. While it has structural aspects (panels, switches), the core identity is the electrical circuit management function it performs.

Identity-Giving Function
✓ done
⚠ not anchored
ElectricalCircuitControlFunction → ElectricalCircuitControlProcess
▼
COPI-Core operation
⚠ Process parent
PlannedProcess reaches no COPI-Core operation, and no gap (out of scope / coverage gap) is recorded.
LLM rationale:
The identity-giving function is the control, connection, and disconnection of various electrical circuits through switches and control apparatus. This distinguishes switchboards from other electrical equipment like transformers or motors.

Genus (genus proximum)
Most specific superclass — may be a domain class like "Valve" or an IOF-Core root.
BFO/IOF-Core Root
bfo:Object branch
bfo:ObjectAggregate branch
bfo:ImmaterialEntity branch
LLM rationale:
From the parent_candidates, ElectricalEquipment is the most specific and appropriate genus. While 'SWITCHING DEVICE' is mentioned in iso15926, ElectricalEquipment provides better taxonomic structure. Circuit breaker is already enriched under ElectricalEquipment, establishing precedent. Switchboards are assemblies of panels, switches, and control apparatus forming a causally unified unit.

Only what is not already entailed by the genus.
Differentia expression
Differentia (natural language)
LLM rationale:
The differentia requires panels (structural housing), electrical switches (control mechanisms), and the specific circuit control function. This distinguishes switchboards from other electrical equipment that may have switches but lack the panel-based multi-circuit control architecture.

Necessary Parts
✓ done
Panel, ElectricalSwitch, ControlIndicator
▼
Consider part-whole relations beyond subsumption:
hasComponentPartAtAllTimes (universal, structurally essential)
· hasComponentPartAtSomeTime (contingent, optional component)
LLM rationale:
These parts constitute the minimal necessary components for any switchboard - the panel provides housing and organization, switches enable circuit control, and indicators provide operational feedback.

Inputs (I)
Outputs (O)
Transformation (T)
LLM rationale:
Switchboards receive electrical power from a source and distribute it to multiple controlled circuits. The transformation is organizational/control rather than energetic - they route and control but do not convert electrical energy.
