A junction box is an enclosure within which cables are connected.

History: New in IFC4

7.4.4.37.2 Applicable entities

7.4.4.37.3 Properties

Name Property Type Data Type Description
Reference IfcPropertySingleValue IfcIdentifier

Reference ID for this specified type in this project (e.g. type 'A-1'), Also referred to as "construction type". It should be provided as an alternative to the name of the "object type", if the software does not support object types and no classification reference to a recognized classification system used.

Status IfcPropertyEnumeratedValue PEnum_ElementStatus

Status of the element, predominately used in renovation or retrofitting projects. The status can be assigned to as "New" - element designed as new addition, "Existing" - element exists and remains, "Demolish" - element existed but is to be demolished, "Temporary" - element will exists only temporary (like a temporary support structure).

NumberOfGangs IfcPropertySingleValue IfcCountMeasure

Number of gangs in the object.

Number of slots available for switches/outlets (most commonly 1, 2, 3, or 4).

ClearDepth IfcPropertySingleValue IfcPositiveLengthMeasure

The clear depth.

It indicates the unobstructed depth available for cable inclusion within the junction box.

ShapeType IfcPropertyEnumeratedValue PEnum_JunctionBoxShapeType

Shape of the junction box.

PlacingType IfcPropertyEnumeratedValue PEnum_JunctionBoxPlacingType

Location at which the type of junction box can be located.

JunctionBoxMountingType IfcPropertyEnumeratedValue PEnum_JunctionBoxMountingType

Method of mounting to be adopted for the type of junction box.

IsExternal IfcPropertySingleValue IfcBoolean

Indication whether the element is designed for use in the exterior (TRUE) or not (FALSE). If (TRUE) it is an external element and faces the outside of the building.

IP_Code IfcPropertySingleValue IfcLabel

IP Code, the International Protection Marking, IEC 60529), classifies and rates the degree of protection provided against intrusion.

NominalLength IfcPropertySingleValue IfcNonNegativeLengthMeasure

The nominal overall length of the object. The size information is provided in addition to the shape representation and the geometric parameters used within. In case of inconsistency between the geometric parameters and the size properties, provided in the attached property set, the geometric parameters take precedence.

NominalWidth IfcPropertySingleValue IfcNonNegativeLengthMeasure

The nominal overall width of the object. The size information is provided in addition to the shape representation and the geometric parameters used within. In cases of inconsistency between the geometric parameters and the size properties, provided in the attached property set, the geometric parameters take precedence.

NominalHeight IfcPropertySingleValue IfcNonNegativeLengthMeasure

The nominal height of the object. The size information is provided in addition to the shape representation and the geometric parameters used within. In cases of inconsistency between the geometric parameters and the size properties, provided in the attached property set, the geometric parameters take precedence.
