Model Electrical Distribution Board

Overview

This functional part describes the information required to describe an electrical distribution board type and occurrence. An electrical distribution board provides a housing for an aggregation of different types of instances of electrical distribution elements so that they can be viewed, operated or acted upon from a single place. Each item in the aggregation may have its own geometric representation and location by virtue of being a subtype of IfcProduct.
Electrical distribution board types are distinguished by type including:

Alarm panel
Consumer unit
Control panel
Distribution board
Gas detector panel
Mimic panel
Motor control centre
Switchboard
Users can also define other functions as necessary
The shape representation for an electrical distribution board may be defined (particularly so if contained within a casing); alternatively, the shape representation may be derived from the elements that are aggregated into the distribution point.
Only elements that are distinctly for the purposes of electrical power distribution may be aggregated into an occurrence of a distribution boar. This is identified within this functional part by specifying the range of type/occurrence elements that are specifically allowed within the aggregation.

Results

Model of electrical distribution board types and occurrences including shape representation and elements aggregated within the distribution point.

Description	Entity/Pset/Functional Part	MAN	REC	OPT
Set the type of the distribution board, represent and place
Set the type of the electrical distribution board The following are the allowed types: Alarm Panel Consumer Unit Control Panel Distribution Board Gas Detector Panel Motor Control Centre Switchboard User Defined Not Defined	IfcElectricDistributionBoardType.PredefinedType?IfcElectricDistributionBoardTypeEnum
If the value of the type is set to USERDEFINED, then establish the value that the user wishes to set.	IfcElectricDistributionBoardType.ObjectType::IfcLabel
The shape representation of the distribution board may be established using any of the forms identified with the representation functional parts or there may be no shape representation at all. Note that a distribution board type may have several representations.	IfcElectricDistributionBoardType.Representation::fp_represent_product
The object must be placed and oriented appropriately.	IfcElectricDistributionBoardType.ObjectPlacement::fp_place_object
Assert general attributes
Assert the owner history	IfcElectricDistributionBoardType.OwnerHistory::fp_apply_owner_history
Specify a name	IfcElectricDistributionBoardType.Name::IfcLabel
Specify a description	IfcElectricDistributionBoardType.Description::IfcText
Assert the occurrence of the distribution board and set its type
Define the type of distribution board to which the occurrence conforms. The type that is being defined is an IfcElectricDistributionBoardType and this is the relating type. The occurrence of a distribution board is an IfcFlowController. This is the related object.	fp_define_by_type
Define properties for the occurrence Values of properties within the property set Pset_FlowControllerElectricDistributionBoardType may be set as necessary.
Specify if the current instance is a main distribution point/topmost level in an electrical distribution hierarchy (= TRUE) or a sub-main distribution board (= FALSE).	Pset_FlowControllerElectricDistributionBoardType.IsMain::IfcPropertySingleValue::IfcBoolean
Specify if the current instance requires a skilled person or instructed person to perform operations on the distribution board (= TRUE) or whether operations may be performed by a person without appropriate skills or instruction (= FALSE).	Pset_FlowControllerElectricDistributionBoardType.NumberOfDoors ::IsSkilledOperator::IfcInteger
Assert general attributes for the occurrence
Assert the owner history of the equipment occurrence	IfcFlowController.OwnerHistory::fp_apply_owner_history
Set a name to the equipment occurrence	IfcFlowController.Name::IfcLabel
Provide a description of the equipment occurrence	IfcFlowController.Description::IfcText
Aggregate the elements into the electrical distribution board
Determine the elements that are to be aggregated into the distribution board. Elements that can be aggregated for this purpose include: IfcCableCarrierFittingType IfcCableCarrierSegmentType _IfcCableSegmentType IfcElectricFlowStorageDeviceType IfcElectricTimeControlType IfcEnergyConversionDevice IfcEnergyConversionDeviceType IfcFlowController IfcFlowControllerType IfcFlowFitting IfcFlowFittingType IfcFlowSegment IfcFlowSegmentType IfcFlowStorageDevice IfcFlowStorageDeviceType IfcFlowTerminal IfcFlowTerminalType IfcJunctionBoxType IfcLampType IfcOutletType IfcProtectiveDeviceType IfcProtectiveDeviceTrippingUnitType IfcSwitchingDeviceType IfcTransformerType
Aggregate the elemets	fp_aggregates (IcFlowController [of type = IfcElectricDistributionBoardType], [elements as listed above])
Extend occurrence information
Additional information may be asserted for the occurrence using general data as necessary (such as material, classification or quantity association etc.
