About Voltage Definitions

The Voltage Definitions table defines the ranges of voltages that can be assigned to the Distribution Systems available in your project.

Each voltage definition is specified as a range of voltages to allow for differing voltage ratings on devices from various manufacturers. For example, devices used on a 120V distribution system may carry ratings of anywhere from 110V to 130V.

You can create Voltage Definitions and you can delete definitions that are not currently in use with any distribution system.

• Name - This identifies a voltage definition.
• Value - This is the actual voltage for the voltage definition.
• Minimum - This is the lowest voltage rating for electrical devices and equipment that can be used with the voltage definition.
• Maximum - This is the highest voltage rating for electrical devices and equipment that can be used with the voltage definition.

Note: Revit does not prevent you from specifying unfeasible voltage values. For example, you could configure a distribution system with a L-L Voltage value of 120 and an L-G Voltage value of 480, even though this is physically impossible.
