class Ifc4::IfcElectricDistributionBoard : public Ifc4::IfcFlowController

A distribution board is a flow controller in which instances of electrical devices are brought together at a single place for a particular purpose. A distribution provides a housing for connected electrical distribution elements so that they can be viewed, operated or acted upon from a single place. Each connected item may have its own geometric representation and location.

HISTORY New entity in IFC2x4

Type Use Definition IfcElectricDistributionBoard defines the occurrence of any electric distribution board; common information about electric distribution board types is handled by IfcElectricDistributionBoardType. The IfcElectricDistributionBoardType (if present) may establish the common type name, usage (predefined type), properties, materials, ports, composition, assignments, and representations. The IfcElectricDistributionBoardType is attached using the IfcRelDefinesByType objectified relationship and is accessible by the IsTypedBy inverse attribute. If the IfcElectricDistributionBoardType has ports or aggregated elements, such objects are reflected at the IfcElectricDistributionBoard occurrence using the IfcRelDefinesByObject relationship. Figure 198 illustrates electric distribution board type use. Figure 198 — Electric distribution board type use

Property Use Definition The property sets relating to this entity are defined by IfcPropertySet and attached by the IfcRelDefinesByProperties relationship. They are accessible by the IsDefinedBy inverse attribute. Property sets may also be specified at the IfcElectricDistributionBoardType, defining the common property data for all occurrences of the same type. They are then accessible by the IsTypedBy inverse attribute pointing to IfcElectricDistributionBoardType.HasPropertySets. If both are given, then the properties directly defined at IfcElectricDistributionBoard override the properties defined at IfcElectricDistributionBoardType. Refer to the documentation at the supertype IfcFlowController and ancestors for inherited property set definitions. The following property set definitions are applicable to this entity: Pset_ElectricDistributionBoardTypeCommon (PSET_TYPEDRIVENOVERRIDE)

Quantity Use Definition The quantities relating to this entity are defined by IfcElementQuantity and attached by the IfcRelDefinesByProperties relationship. They are accessible by the IsDefinedBy inverse attribute. The following base quantities are defined and shall be exchanged with the IfcElementQuantity.Name = ‘BaseQuantities’. Other quantities, being subjected to local standard of measurement, may be defined with another string value assigned to Name. In this case a valid value for MethodOfMeasurement shall be provided.

Qto_ElectricDistributionBoardBaseQuantities

Material Use Definition The material of the IfcElectricDistributionBoard is defined by IfcMaterialConstituentSet or as a fallback by IfcMaterial, and attached by the RelatingMaterial attribute on the IfcRelAssociatesMaterial relationship. It is accessible by the HasAssociations inverse attribute. Material information can also be given at the IfcElectricDistributionBoardType, defining the common attribute data for all occurrences of the same type. The following keywords for IfcMaterialConstituentSet.MaterialConstituents[n].Name shall be used:

Casing: Material from which the casing is constructed.

Port Use Definition The distribution ports relating to the IfcElectricDistributionBoard are defined by IfcDistributionPort and attached by the IfcRelConnectsPortToElement relationship. If the electric distribution board occurrence is defined by IfcElectricDistributionBoardType, then the port occurrences must reflect those defined at the IfcElectricDistributionBoardType using the IfcRelDefinesByObject relationship. Ports are specific to the IfcElectricDistributionBoard PredefinedType as follows indicated by the IfcDistributionPort Name, PredefinedType, and FlowDirection:

CONSUMERUNIT

Line (ELECTRICAL, SINK): Incoming power, such as a cable connecting from the electrical utility or another distribution board. Ground (EARTHING, SOURCE): Grounding connection, such as a cable connecting to a cable fitting connected to a cold water pipe segment coming from the ground. Circuit#1 (ELECTRICAL, SOURCE): A downstream circuit, typically a circuit breaker protective device. Circuit#2 (ELECTRICAL, SOURCE): A downstream circuit, typically a circuit breaker protective device. Circuit#3 (ELECTRICAL, SOURCE): A downstream circuit, typically a circuit breaker protective device. Circuit#4 (ELECTRICAL, SOURCE): A downstream circuit, typically a circuit breaker protective device. Circuit#5 (ELECTRICAL, SOURCE): A downstream circuit, typically a circuit breaker protective device. Circuit#6 (ELECTRICAL, SOURCE): A downstream circuit, typically a circuit breaker protective device. Circuit#7 (ELECTRICAL, SOURCE): A downstream circuit, typically a circuit breaker protective device. Circuit#8 (ELECTRICAL, SOURCE): A downstream circuit, typically a circuit breaker protective device.
