6.2.3.3 IfcDistributionCircuit
6.2.3.3.1 Semantic definition
A distribution circuit is a partition of a distribution system that is conditionally switched such as an electrical circuit.
*Composition Use Definition*
An IfcDistributionCircuit may aggregate an IfcDistributionSystem using the IfcRelAggregates relationship where RelatingObject refers to the IfcDistributionSystem and RelatedObjects includes one or more IfcDistributionCircuit groups.
An IfcDistributionCircuit may be aggregated into sub-circuits using the IfcRelAggregates relationship where RelatingObject refers to the parent IfcDistributionCircuit and RelatedObjects refers to one or more IfcDistributionCircuit sub-circuits.
*Assignment Use Definition*
An IfcDistributionCircuit should be assigned to an IfcDistributionPort on an IfcFlowController element indicating the host or origination of the system using the IfcRelAssignsToProduct relationship.
Each device whose operation is conditional based upon the state of the circuit is assigned to the IfcDistributionCircuit via the IfcRelAssignsToGroup relationship. An IfcDistributionElement may belong to multiple systems or circuits, however only one IfcDistributionSystem or IfcDistributionCircuit of a particular PredefinedType.
