Axiomatization Decision LogRegistro de Decisões
1 Identity-Giving FunctionFunção Identitária
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 DeterminationDeterminação do Gênero
Assemblybfo:Object (BFO_0000030)
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 Differentia SpecificaDiferença Específica
∃hasComponentPartAtAllTimes.Panel ⊓ ∃hasComponentPartAtAllTimes.ElectricalSwitch ⊓ ∃bearerOf.ElectricalCircuitControlFunctionA switchboard is electrical equipment that bears panels accommodating switches and control apparatus for managing electrical circuits.
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.
4 Necessary PartsPartes Necessárias
| 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.

TransformationTransformação
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.
Disjoint WithDisjunto com
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)
