7.8.4.39.3 Properties
| Name | Property Type | Data Type | Description | |
|---|---|---|---|---|
| RatedCurrent | IfcPropertyBoundedValue | IfcElectricCurrentMeasure |
The current that a device is designed to handle. |
|
| RatedVoltage | IfcPropertyBoundedValue | IfcElectricVoltageMeasure |
The range of allowed voltage that a device is certified to handle. The upper bound of this value is the maximum. |
|
| InsulationVoltage | IfcPropertySingleValue | IfcElectricVoltageMeasure |
The insulation voltage. The max voltage for normal insulation operation. |
|
| BreakdownVoltageTolerance | IfcPropertySingleValue | IfcElectricVoltageMeasure |
Nominal value of the spark gap breakdown voltage tolerance. |

The temperature range in which the device operates normally. |
|
| CreepageDistance | IfcPropertySingleValue | IfcPositiveLengthMeasure |
Shortest distance or the sum of the shortest distances along the surface on an insulator between two conductive parts which normally have the operating voltage between them. (IEV ref 471-01-04) |
|
| InstallationMethod | IfcPropertySingleValue | IfcLabel |
Method of installation of cable/conductor. Installation methods are typically defined by reference in standards such as IEC 60364-5-52, table 52A-1 or BS7671 Appendix 4 Table 4A1 etc. Selection of the value to be used should be determined from such a standard according to local usage. |
