Entity definition

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.

RuleDescription
CorrectPredefinedTypeEither the PredefinedType attribute is unset (e.g. because an IfcElectricDistributionBoardType is associated), or the inherited attribute ObjectType shall be provided, if the PredefinedType is set to USERDEFINED.
CorrectTypeAssignedEither there is no electric distribution board type object associated, i.e. the IsTypedBy inverse relationship is not provided, or the associated type object has to be of type IfcElectricDistributionBoardType.
