#### 7.2.3.9 IfcElectricAppliance

| Appareil électrique
| Elektrisches Gerät

An electric appliance is a device intended for consumer usage that is powered by electricity.

Electric appliances may be fixed in place or may be able to be moved from one space to another. Electric appliances require an electrical supply that may be supplied either by an electrical circuit or provided from a local battery source.

Body Geometry

The Body Geometry concept applies to this entity as shown in Table 87.

RepresentationType | Geometry | Description
--- | --- | ---
Brep | IfcFacetedBrep | All fixtures (all non distribution flow elements, i.e. everything which is not a duct, a pipe, a cable, or a cable carrier) should be defined by an b-rep geometry. This includes also the complex flow fitting elements (e.g. Y branch or T branch) or distribution flow elements with size changes (e.g. reducer).
SurfaceModel | IfcFaceBasedSurfaceModel | If the geometric model consistency of a b-rep shape representation can not be guaranteed (arcwise connected volume bounded by faces, each being connected, oriented, finite, closed 2-manifold), a surface representation based on open shells should be used.
SweptSolid | IfcExtrudedAreaSolid | All "simple" distribution flow elements (general ducts and pipes) are defined by sweep geometry.
SectionedSpine | IfcSectionedSpine | If only the analytical shape is required for which the exact interpolation between the cross sections is not required, a sectioned spine can be used.
CSG | IfcCsgSolid |
Tessellation | IfcTriangulatedFaceSet |
MappedRepresentation | IfcMappedItem | All occurrences of IfcDistributionElement (and its subtypes) should (whenever possible) share a representation map established by the assigned type. The geometric representation of the occurrence is then an IfcMappedItem.
