Axiomatization Decision Log
1
Identity-Giving Function
Function class
ElectricalCircuitControlFunction
⊑ DesignedFunction
Realized in
ElectricalCircuitControlProcess
⊑ PlannedProcess
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.
2
Genus Determination
Assembly
bfo:Object (BFO_0000030)
Causally unified material artefact composed of physically connected,
separable MaterialComponent parts. Satisfies
Assembly ⊑ MaterialArtifact ⊑ bfo:Object.
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.
3
Necessary Parts
| Part class | Parent | Relation |
|---|---|---|
| Panel | MaterialArtifact | hasComponentPartAtAllTimes |
| ElectricalSwitch | MaterialArtifact | hasComponentPartAtAllTimes |
| ControlIndicator | MaterialArtifact | hasComponentPartAtAllTimes |
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.
4
Process Participation Signature ⟨I, O, T⟩
Inputs (I)
—
Outputs (O)
—
Transformation (T)
electrical circuit switching and control - no power conversion, pure routing control
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.
5
Axiom Mode Decision
Necessary + Sufficient
— modelled as a defined class
(≡, EquivalentClass). Automatic classification is
appropriate for this concept.
Disjointness Axioms
Transformer
ElectricMotor
C2: Transformer. C4: ElectricMotor. Transformers perform voltage/current conversion (incompatible with pure switching), motors convert electrical to mechanical energy (incompatible with circuit control distribution)
Cross-Standard Observations
All three sources (ISO 15926, CFIHOS, POSC Caesar) provide highly consistent definitions focusing on panels, switches, and circuit control. ISO 15926 adds 'indicators and other apparatus' while others mention 'controlgear'. The functional core (connecting/disconnecting circuits) is unanimous across sources.
