IFC class for earthing rod

[namio.sousa]

Is there any IFC class to classify an earthing rod?

I’m not an expert on this, but think the closest generalisation of earthing rod would be the IfcCableSegment and you can apply the predefined type: CONDUCTORSEGMENT. Alternatively IfcProtectiveDevice.

IFC4.4 will likely introduce an IfcEarthingElement as a subtype of IfcFlowTerminal with several predefinedtypes including GROUNDINGROD.
